Flotation is usually used by large scale miners but can also be applied in small scale operations. It is a process that works best for processing complex ore types, especially ores that are difficult to process using gravity methods. In flotation, a mixture of slurry (crushed ore and water) and frothing agents are added into a flotation machine.

Africa Sodium Cyanide Market

Typically, gold is extracted from its ore using sodium cyanide through leeching. In this process, the ore is crushed into a fine powder using industrial machinery. Then, the dust is added to a solution of sodium cyanide (NaCN) and allowed to process. During the process, the gold molecules form very strong bonds with the NaCN, becoming water
