phosphate ore leaching process

Phosphate Ore Leaching Process

Ore processing consists of the following stages 1 Crushing and grinding of the ore 2 Addition of process water generally decanted from the tailings pond to form a slurry 3 Addition of lime to the ore, and cyanide solution to the slurry, to leach the gold and silver into solution 4 Addition of carbon to adsorb dissolved.

Heap leaching is generally used to recover gold from low-grade ore, while tank leaching is used for higher grade ore. Cyanidation is the primary means of recovery of fine gold and silver. In this process, solutions of sodium or potassium cyanide are brought into contact with an ore, which may or may not have required extensive preparation prior to leaching. Gold and silver are
