Zenith flotation cell for Gold Ore separation Mining Machinery
flotation cell introduction
flotation cell have three different types, the following is details of each type:
flotation cell for Gold Ore separation Mining Machinery:
flotation cell process is one of the most widely used methods to process lode gold in gold beneficiation plant. In most instances, flotation cell is used for processing sulfide minerals gold ores with high flotability and the effect is most notable.
1. General process
Primary Crushing----Secondary Crushing----Sieving----Third Crushing-----Grinding--- Classifying-----Flotation Separation----drying---- Concentrated ore
2. Application
flotation cell is used for upgrading ores. After this process, the value of final concentrated powder will be greatly improved.
Our basic process is crushing, grinding, sieving, flotation separating and dewatering. The specific process is different according to ore, site and customers' requirements.
Mining gold ore first preliminary crushing by jaw crusher, crushing to a reasonable degree of fineness via hoist feeder evenly fed into the ball mill, ore crushing, grinding by ball mill.
After a ball mill grinding of ore fines go to the next step:classification.Spiral sorting machine by means of the proportion of solid particles precipitated in the liquid at different speeds principle,the ore mixture enters the grading machine washing,grading.
After washed and graded mineral mixture through the flotation cell, Adding different drugs through the flotation machine after the initial separation of the mineral particles in the flotation machine is fed, depending on the mineral characteristics,so that the minerals and other substances to be separated.After the desired minerals are separated out, because the preliminary concentrated containing a lot of water,subject to the concentrator, and then through a dryer to obtain dry minerals.
flotation cell :
flotation cell principle is that: using gravity separation to recover gold and all kinds of associated heavy minerals from the ore mineral sands as much as possible. Then gravity separation, flotation, mercury mixing, magnetic separation and electrostatic separation are combined to separate the gold and all kinds of heavy minerals, which can reach the purpose of comprehensive recovery. gold gravel mine beneficiation can be classified into crushing and sieving, desliming and beneficiation.
Practice proves that the gravity separation method is the most effective and the most economic method for processing alluvial gold mine. For the different grain size composition in alluvial gold, all kinds of gravity separation equipments have different effective grain size limits in materials processing, so reasonable alluvial gold beneficiation process should be the combined work by several gravity separation equipments.
Gold concentrate are got by through coarse beneficiation. Its gold content is 100 g/tons and heavy sand minerals are 1 ~ 2 kg/tons or more. For coarse concentrates that includes gold, there are three kinds of processing methods:
1. Using batea, the gold grains are dressed out in manual work and the heavy sands are abandoned.
2. Using mercury mixing tube for mercury mixing, the calomelene is got and the heavy sand aren abandoned.
3. Using manual work and mercury mixing for gold extraction, the heavy sands are sent to concentration plants. All kinds of heavy sand minerals can be recycled in magnetic separation and electricity separation.
flotation cell Process Plant:
flotation cell is widely used for recovery of gold from cyanide solutions. The process can be applied to clean solutions through fluidized bed adsorption columns, or directly to leached ore slurries by the addition of carbon to agitated slurry tanks, followed by separation of
the carbon from the slurry by coarse screening methods.
Gold cyanide is adsorbed into the pores of activated carbon, resulting in a process solution that is devoid of gold. The loaded carbon is heated by a strong solution of hot caustic and cyanide to reverse the adsorption process and strip the carbon of gold. Gold is then removed from the solution by electrowinning. Stripped carbon is returned to adsorption for reuse.
The major advantage of carbon-in-pulp recovery over Merrill Crowe recovery is the elimination of the leached ore solids and liquid separation unit operation. The separation step typically involves a series of expensive gravity separation thickeners or continuous filters arranged for countercurrent washing or filtration of the solids. For ores exhibiting slow settling or filtration rates, such as ores with high clay content, the countercurrent decantation (CCD) step can become cost prohibitive. Ores with high silver content will generally suggest that Merrill-Crowe recovery be used. This is because of the very large carbon stripping and electrowinning systems required for processing large quantities of silver. Carbon-In-Pulp (CIP): Carbon-in-pulp operation is a variation of the conventional cyanidation process. Ore is crushed, finely ground, and cyanide leached in a series of agitated tanks to solubilize the gold values. Instead of separating solids from the pregnant solution, as in the traditional cyanidation process, granular activated carbon is added to the leached slurry.
The carbon adsorbs the gold from the slurry solution and is removed from the slurry by coarse screening. In practice, this is accomplished by a series of five or six agitated tanks where carbon and ore slurry are contacted in a staged countercurrent manner.
This greatly increases the possible gold loading onto the carbon while maintaining a high recovery percentage. Carbon is retained within the individual CIP tanks by CIP tank screens. The opening size of the CIP tank screens is such that the finely ground ore particles will pass through the screens,
but the coarse carbon will not. Almost every imaginable type of screen has been tried for this application, with some types being much more successful than the rest.
