At one plant an 18- by 18-ft. Devereux requires 15 hp. when agitating a pulp containing 62 per cent solids. Turbo and Wallace. The Turbo and the Wallace are high-speed impeller types of agitator imparting high velocity to the pulp and are suited for relatively small-diameter flat-bottomed tanks.

Many opportunities exist throughout the world for small cyanide plants, possibly using a Gold Leaching Process, both for production and pilot operations, especially in areas not easily accessible, and where labor and local costs are on a level for profitable operation.Ores not fully amenable to treatment by amalgamation or flotation processes for the recovery of gold …

[Show full abstract] understanding this leaching behavior of gold ores, the grinding, classification and leaching sections of a gold processing plant are analyzed through reconciliation of ...

In processing gold, once it is completely dissolved the solution that is formed by that dissolved gold is called the 'PREG' or short for PREGNANT SOLUTION. In other words solution that is full of gold and is accordingly yellow in shade/colour. The solids are now considered the waste and the liquid is the concentrate.

Our inventory includes complete gold processing plants, silver processing plants, as well as plants for recovery other precious metals and rare earth minerals.

Cyanidation as applied to ordinary gold and silver ores is a relatively simple process. When cyanicides {cyanide-consuming elements) are encountered in small amounts in the treatment of such ores, the various schemes already discussed, such as use of a lead salt or wasting barren solution, can usually be resorted to and successful operation maintained.
