The gold mining industry is presented as an overview covering key aspects and examples regarding gold discovery, deposits, and production. Segmentation of gold ore types is made based on major processing routes, ie., free milling, refractory, heap leachable, and concentrate sales.
The Mining Process Waihi Gold
A slurry of ground ore, water and a weak cyanide solution is fed into large steel leach tanks where the gold and silver are dissolved. Following this leaching process the slurry passes through six adsorption tanks containing carbon granules which adsorb the gold and silver. This process removes 93% of the gold and 70% of the silver.
Gold Milling Process Primitive and Basic

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.

Yet mining the ore is just one stage in a long and complex gold mining process. Long before any gold can be extracted, significant exploration and development needs to take place, both to determine, as accurately as possible, the size of the deposit as well as how to extract and process the ore efficiently, safely and responsibly.
By product gold mining. Gold is also produced by mining in which it is not the principal product. Gold ore processing In placer mines, the gold is recovered by gravity separation. or in rivers, with oxygen tubes in their mouths. They also process gold with mercury, a toxic metal, risking irreversible health damage from mercury poisoning
