Gold Cyanidation Process - Mineral Processing

The Cyanidation Process or CYANIDE LEACHING is ‘most notably used in the recovery of gold. Safety and environmental concerns are of prime importance in the operation of a cyanidation plant. As we get farther into this type of recovery you will see why. The preparation of the ore for processing is similar to flotation. The ore must be ground to a specific size before it can be treated. But ...

Fine Grinding for Cyanidation

This plant, near Marysville, Mont., was planned to treat the ore from the Piegan and Gloster mines, the latter being one of the early and famous producers of the Marysville district. When the mill was closed in 1888, treatment consisted of stamp milling, followed by pans and settlers for pan amalgamation. The extraction was evidently poor, because, a few years later, thousands of tons of ...

Everything about Gold Processing, Smelting,

Cyanidation. The Cyanidation process contributes to the recovery of more gold. The process is about oxidation and dissolving of metallic gold in an alkaline cyanide solution. Atmospheric oxygen acts as the oxidant in the process. The oxidant helps to dissolve the gold and forms sodium hydroxide as well as sodium cyanoaurite.
