Gold Recovery : 8 Steps (with Pictures) - Instructables
This page offers a comparative review of gold recovery. Gold processing Britannica. By 2000 bc the process of purifying gold-silver alloys with salt to remove the silver was developed. The mining of alluvial deposits and, later, lode or vein deposits required crushing prior to gold extraction, and this consumed immense amounts of manpower .
processes in extraction of gold
Refining from scrap The processing of gold scrap varies not only with the gold content but also with the amenability of the gold in the scrap to extraction. Thus, the bulk of the gold may be recovered by leaching techniques using cyanidation or aqueous chlorination, and the residue may then be treated by smelting to recover the balance.

Extracting Gold | HowStuffWorks
Removing the gold-bearing rock from the ground is just the first step. To isolate pure gold, mining companies use a complex extraction process. The first step in this process is breaking down large chunks of rock into smaller pieces. At a mill, large machines known as crushers reduce the ore to pieces no larger than road gravel.
