1. Overview of Gold Ore Processing. Gold ore processing involves several stages, including extraction, crushing, milling, and recovery. The primary methods used for processing gold ores are gravity separation, flotation, and cyanidation. Each method has its own cost implications based on the complexity of the ore and the desired recovery rate. 1.1.

Gold carbon-in-pulp(CIP) is a typical gold beneficiation process for the effective recovery of gold-bearing minerals with a high oxidation degree and low grade of raw ore. Gold CIP has become a widely used gold extraction method worldwide because of its advantages of high adsorption rate, high recovery rate, and low investment cost.
