Gold Milling and Concentration | breckheritage
Before the gold found in the ore taken from hard rock mines became gold ingots or gold coins, it went several complicated rounds of chemical and mechanical processing. Men and machines at mills worked together to pulverize and break down the ore, discard the waste rock and prepare the concentrated ore for further processing.

—Many of the ores we run would come under the head of " rich spotty " ores, as the Colorado phrase is. To crush and cut down such an ore, according to best Colorado rules of sampling, would require breaking the whole batch of from 500 to 1,000 lb. down to 10 or even 30-mesh. This would ruin our gold stamp-mill run.

Sulphide Gold Recovery. Pre-concentration of coarse 350 – 500 micron sulphide-associated gold ore, using the InLine Pressure Jig, is required to reject gangue from the high value material. The IPJ, a classic pre-concentration device, is effective in gangue rejection prior to further processing of valuable gold-bearing material.

Gold Recovery 101 - Mineral Processing Equipment & Solutions
Free-Milling Gold Gold ore is considered free-milling when over 90% of the gold can be recovered by a conventional gravity-cyanidation process with low reagent consumptions at a grind size of 80% passing 75 µm. Some examples of free-milling gold ores include quartz-veined deposits and oxidized ores. Sulfide-Associated Gold

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:
