Intensive cyanide Leach

Gravity concentrator (/Gemini/gold cone) produce a smeltable concentrate but are intensive to use and you need to justify the use of them versus the effort to get the gold out. Tabling BEFORE the reactor removes coarse gold that the reactor might not recover, and the reactor leaches the fine gold that the table misses.

Gold Metallurgy and Leaching Process

 · Leaching, often gold, is the process of extracting a soluble constituent from a solid by means of a solvent. In extractive metallurgy, of gold, it is the process of dissolving a certain mineral (or minerals) from an ore or a concentrate, or dissolving certain constituents from materials such as a calcines, mattes, scrap alloys, anodic slimes, etc., to achieve either one or two purposes:
