The gasification temperature of mercury is much lower than the melting and boiling point of gold. Distillation is most commonly used method for separating mercury and gold from amalgam. The solid mercury ointment in gold separator enrichment plant can be distilled periodically. Working Principle: As a kind of gold separator, the purpose of mercury ointment distillation tank is to separate the gold from the mercury components of the gold amalgam. By applying heat to the amalgam, the mercury is burnt off as a gas, which passes along the pipe to re-condense as a liquid. The gold remains in the distilling chamber of the tank, while the mercury is collected at the discharge end in liquid form. Features: 1. Small machine body, easy to carry and move. 2. High distillation efficiency, simple operation. 3. Compact structure with special cooling installations for water which ensures mercury liquefaction completely. 4. Special emptying device avoids mercury harm to users. More about Gold Separator: There are many ways to increase the concentration of the wanted minerals: the method chosen will depend on the relative physical and surface chemical properties of the mineral and the ore. Forui gold separator is a gold enrichment plant which includes Amalgamation Barrel and Mercury Ointment Distillation Tank and other gold separator like gravity separator, jig machine, etc. We give you on-site operation of our gold separator with your gold mineral sample.

I.e. gravity separation is the only rough separation method for alluvial tin and alluvial gold mine. That is because tin and gold content is low comparing with other minerals, and kind of high-efficient and energy-saving extraction method and equipment shall be needed to enrich tin and gold from the alluvial mines. And here gravity separation is, obviously, kind of an ideal beneficiation method to get high grade tin and gold concentrate. A great enrichment efficiency can be seen from the picture. Actually, a complex processing of screening-ore washing-jigging upgrading is needed to get high grade tin concentrate in the picture. 1. Alluvial tin ore washing plant There are many stones or gravels without any tin element in the raw alluvial tin ore, and this will lower the following gravity separation. So the first step is to remove the stone blocks from the raw ore to improve the handling capacity and guarantee the enrichment efficiency. The common screen for alluvial tin ore is rotary screen like the picture above shows. 2. Alluvial tin ore washing equipment For alluvial tin ore with a lot of sticky clay, ore washing will be needed to break the clay blocks besides screening. This will lower the possibility of tin coated by clay and improve the recovery rate and concentrating efficiency as well. The ore washing machine for alluvial tin ore is usually rotary washing machine, ore log washer. 3. Tin processing machine-gravity jig separator There are still a lot of impurities after screening and washing and gravity separation will be needed as further enrichment. And here the gravity separators are required of large handling capacity and high recovery rate. The low efficient gravity separator of small capacity like shaking table and spiral chute will be out of consideration here. And jigger is usually adopted as gravity separator and can be chosen as tin processing machine. The main jigger for tin extraction is trapezoidal jig separator and down-driven jig concentrator. Generally, high grade tin concentrate can be gained after jig gravity separation for alluvial tin of high single separation degree. For alluvial ore of low single separation degree, further milling will be needed to gain ideal beneficiation efficiency. Here gravity separation as rough separation not only lower the floatation cost and the plant investment, but also gain final concentrate for ore of high single separation degree. Therefore, as a tin processing machine, gravity separation and gravity processing machine is essential to alluvial tin extraction. ]]> http://www.wisecounty.com/Classifieds/a,39420,Tin-Extraction-Jig-Gravity-Equipment.htm Fri, 17 May 2013 03:05:16 +0000 All <![CDATA[Gold Extraction Equipment-gold extraction machine]]> http://www.wisecounty.com/Classifieds/a,39409,Gold-Extraction-Equipment-gold-extraction-machine.htm Gold Extraction Equipment-gold extraction machine http://www.frjigmachine.com http://www.frmining.com Generally speaking, the most commonly used extraction method for gold is gravity separation. And the gravity separator-jig separator is a good gold extraction equipment for gold extraction. Gold of elemental substance is the main existence pattern for placer gold with its density over 16t/m3 and this leads to a big density difference between gold and the impurities, so gravity separation can be the most efficient, most economical way to beneficiate alluvial gold. For alluvial gold gravity extraction, there are a certain percentage of gravels, and a rotary screen or vibration screen will be needed to remove these gravels. Gold in placer gold is usually liberated from impurities, and the fine sand can be fed to the gravity separator for enrichment directly. With the development and research of gravity extraction plants, chutes, jiggers, table concentrators and gold centrifugal separators have ever turned up, and jiggers prove to be the ideal gold extraction equipment plant for the first rough separation to gain high grade gold concentrate with its high recovery rate while centrifugal separators and table concentrators work as secondary further enrichment plant. So the whole processing can be screening--gravity separation--shaking table or centrifugal separator. Forui jiggers have been used to beneficiate alluvial gold in Mongolia, Zimbabwe, Congo and many provinces in China. Jiggers of JT series, LTA series and trapezoidal 2LTC6109/8T is mainly used as alluvial gold extraction equipment or tin extraction equipment. (PS: Trapezoidal 2LTC6109/8T jiggers have begun to work to recover tin from tin sand in Russian since Oct. 2012. ) Also for rock gold ore, most needs floatation separation to extract. And only quartz gold of coarse gold granules carried by pyrite can be enriched by jigger. This kind of quartz gold extraction is usually bounded to work together with rod milling and classifying as a whole beneficiation process. So the general processing flow sheet can be crushing--rod milling--jigging separation--centrifugal separation or amalgamation. Free gold extraction test can be done with our gold extraction machine if samples about 20kg can be available, and detailed flow sheet can be designed with enough details about gold ore known. ]]> http://www.wisecounty.com/Classifieds/a,39409,Gold-Extraction-Equipment-gold-extraction-machine.htm Fri, 17 May 2013 01:46:59 +0000 All <![CDATA[Flotation Separation Machine]]> http://www.wisecounty.com/Classifieds/a,39407,Flotation-Separation-Machine.htm Application of Flotation Separation Machine: http://www.frjigmachine.com http://www.frmining.com Floatation separation is involved to beneficiate gold, copper, graphite, sulfur, talc, molybdenite, nickel, lead, zinc, and some other fine inlay ore. This is a general flow sheet of floatation separation and further details will be needed for an exact flow sheet. Introduction of Flotation Separation Machine: Floatation separation is kind of mineral beneficiation method on basic of mineral physical and chemical difference. Surface of mineral granules can be of hydrophobicity, olepphylic,or hydrophobicity can be activated by a certain chemical. After a processing line, the mineral granules can be combined with the bubbles and floated to the surface of the pulp, and the concentrate will be collected from bubbles. Before floatation separation, the mineral granules shall be made liberated from the gangue, so crushing and milling will be needed to make the mineral size ok for floatation separation. Chemicals needed will be added to the milled pulp and agitator will be used to mix the pulp evenly and make the chemical and mineral granules engaged fully. And this will make the floatability difference bigger. The agitated pulp will be put into the floatation slots stirred and air inflated. Mineral granules with good floatability will attach to the bubble and go up to the pulp surface as mineralized foaming, and it will be overflowed or mechanically scraped to the concentrate slot. Concentrate can be gained after dewatering and drying. Sometimes the useful mineral will be left in the pulp while the unuseful materials with good floatability flow as output, and this is called reverse floatation. Eg.: floating the quartz from iron ore. During the floatation separation, crushers, ball mill, classifier, agitator, floatation separation machine and assistant device will be involved to finish the whole floatation process. Chemicals involved: Collecting agent, foaming agent, regulators can be involved during floatation separation. However, different chemicals as collecting agent, foaming agent, regulators will be needed for different ores. Any needed, you are welcome to Forui.

The color of pure scheelite is orange with big double cone crystal shape, and the tip is transparent with dark orange color. It symbiosis with calcite muscovite and black cassiterite, and the scheelite and calcite are fluorescent. Heated or under ultraviolet radiation, it shows purple. The scheelite ore is the main raw material for tungsten refining. However, the natural scheelite ore is low grade ore which can not be used for industrial production. So the beneficiation is necessary for its usage in industrial production. Here is some picture about the scheelite ore dressing site: The flotation process is the main beneficiation method for scheelite ore. Forui flotation machine can be used as scheelite ore beneficiation equipment beneficiationbeneficiat to extract the low-grade, disseminated scheelite with good recovery and beneficiation effect. But for the coarse disseminated, uneven distributed scheelite ore dressing, flotation method is not a good choice. The following shows why. The following picture is the trial in Forui lab, and much can be seen from it. The coarse-grained disseminated or uneven distributed scheelite ore can be pre-enrichment by gravity separator jigger, even some high-quality scheelite ore dressing also can be done by gravity separator jigger. So we need to break conventional thoughts(flotation process), which requires huge investment and higher operating costs, besides the scheelite is fragile crystals, once over-crushed, the powdered scheelite is very hard to recovery. so the flotation beneficiation equipment is not the best choice for coarse-grained disseminated scheelite ore. Gravity separation is a good substitute way, because it just breake the ore and recover the scheelite crystals, and less over crush happens. Compared with flotation separation, gravity separation need less investment and operation costs. In fact, different ores have different features, especially for some bonanza ores in Africa, so the beneficiation method should in accordance with specific circumstances. The appropriate ore dressing process and beneficiation equipment can help a lot with compared lower investment and more cost-effective. In a word, choose the right beneficiation method before purchasing beneficiation equipment.

If not deal with it appropriately, it will greatly do harm to the environment and human health. Therefore, it is necessary to have concentration plant to deal with the smelting slag. According to the need of customer, Gongyi Forui Machinery Factory did a beneficiation test of silico-manganese smelting slag samples in a smelter in Shanxi. The test plan: There is a great difference in proportion between the slag and alloy, so we can achieve better economic indicators and beneficiation indicators through gravity separation. Test equipment: lab crusher, lab jigger, lab shaker Firstly, crush and screen the original slag, then do the separation test with shaker and jigger. The result shows that the jigger has a larger processing amount and higher efficiency of the separation to deal with the metallurgical slag, whose recycle rate is as expected result. However, the result for the slag of shaker is not very satisfactory, nor does the recycle rate and handling capacity.

The Jigger is the most commonly used gold extraction equipment. There are many types of jigger, diaphragm jigger is a commonly used one. The working principle of diaphragm jigger: When the eccentric drive mechanism drives diaphragm repeadly, the water inside the jigger will generate vertical alternating pulsating force through the sieve. The selected materials above the bed, together with the bed ore and water form a particle swarm system. When the flow impacts upward, the particle swarm has loose suspended state, and the mineral particles of different sizes/wight settle at different speeds, the large density coarse particles (bed stone) deposite on the lower layer. When the water speed slow down, the mineral ores of big density and small particle will enter the lower layer through the bed gap under the suction effect. 1.2 Shaker The shaker gold extraction method depends on shakers for the gold extraction process. The shaker is a extraction equipment which works in the horizontal media stream. It is composed of the bed and the transmission mechanism, the bed is driven by the drive mechanism for vertical reciprocating movement. The mineral extraction is done on the bed surface gradually. Besides the mineral gravity, the factor contributed to the mineral particles movement mainly is differential movemence between rush and bed surface. Ore particles subjected to the stratification perpendicular to the bed and the separation action parallel to the bed surface in the motion. So the result is that different ore particles are discharged from the different bed surface zone. The shaker can be divided into coarse sand bed (> 0.5 mm), fine sand bed (0.5 to 0.074 mm) and mineral mud bed (0.074 to 0.037 mm) according to different mineral particle sizes. ]]> http://www.wisecounty.com/Classifieds/a,39317,Method-of-Gold-Extraction--1.1-Jigging-Separation-1.2-Shaker.htm Wed, 15 May 2013 02:53:09 +0000 All <![CDATA[Gold Extraction Method--1.3 Chute Extraction 1.4 Spiral Concentrator]]> http://www.wisecounty.com/Classifieds/a,39310,Gold-Extraction-Method--1.3-Chute-Extraction-1.4-Spiral-Concentrator.htm Gold Extraction Method--1.3 Chute Extraction 1.4 Spiral Concentrator 1.3 Chute Extraction http://www.frmining.com The chute gold extraction method is an ancient method of gravity separation and is still used today.The main equipment for the chute extraction is gold chute. The chute is an long and narrow wooden (or steel) chute with a inclination of 3° to 4° (maximum of 14° to 16°). The separation principle: After entering the chute from the slot head, the ore slurry of different density separates layers under the combined force effects of the flow force, mineral particles gravity (centrifugal force), the friction between mineral particles and the tank bottom, the high density concentrates settle to the bottom of the tank and the low density particle ore is tailings. With intermittent operation, the chute will stop feeding materials and discharge the concentrate when a certain amount conentrate heeps on the bottom. There are coarse particle chute and slime chute, the former is suitable for dealing with coarse material, the latter is suitable for the treatment of fine grade material. There are bedding and baffle on the bottom of the coarse particle gold extraction chute. The course particle chut is mainly used for the placer gold extraction, works on land (chute length: around 15m) or gold dredger(chute length: 4-6m). 1.4 Spiral Concentrator The spiral concentrator is the main gold extraction machine in spiral concentration gold process. Working principle: The spiral concentrator using gravity, the friction force, the combined effect of the centrifugal force and flow, so that the mineral particles can be separated according to the specific gravity, particle size and shape. Characteristics: The whole chute is bent into a spiral status in the vertical direction. Extraction process: The slurry feeded from the top of the chute flow down along the chute with spiral line movement. and the mineral particles are separated in the flow process. The low density particle is distributed in the outer edge of the spiral grooves, the high density fine particles is distributed in the inner edge of the helical groove.
