Lime in Flotation and Recovery Processes

Lime, a key player in recovering copper, zinc, nickel and lead, regulates the pH level. By doing so, lime enables the depression of certain unwanted materials, preventing them from floating and thus activating pure desired materials to separate from other minerals.

Lime is crucial for recovering gold and silver. Run-of-mine, milled, autoclaved, or roasted ores are combined with lime and a cyanide solution. Lime compliments the cyanide solution by maintaining the correct pH and preventing the formation of hazardous hydrogen cyanide gas, while cyanide dissolves the gold and silver.

Using lime effectively requires skill and expertise. However, Rajasthan Lime’s technical team can assist in defining the optimum lime mixing and slaking solutions.
