The addition of lime in the flotation operation is usually carried out by adding the lime powder to the ore belt of the ball mill or adding lime milk or lime powder to the stirring tank before the flotationPreventing the hydrolysis of sodium cyanide of nacn to reduce the concentration of a solution of hcn prevent volatilization of hcn.
The slurry will enter into 6 sets of double impeller leaching tank one by one; well-mixed sodium cyanide agents are added to the 6 tanks; after leaching the gold bearing slurry goes to the thickener; and after thickening the pregnant solution will go to four-stage carbon column and after the adsorption it becomes the barren solution which is pumped to the thickener and the tailing goes to.
When examining industrial facilities industrial archaeologists often pay greater attention to the facilities' products than they do to the facilities' byproductsNevertheless paying close attention to byproducts is an important facet of making an industrial facility profitableThis articl examines the standard mill a turn-of-the-20th-century facility for treating gold ores at bodie.
