The process of gold

Aug 31, 2020

The gold in the veins can be in many different forms like nuggets or sheets, or in gold compounds. In recovering gold from vein ore, the ore is first crushed in rod or ball mills. In this process the ore is crushed to a powdery substance from which the gold can be extracted by gravity separation

    The principal gold minerals that affect the processing of gold ores are native gold, electrum, Au-Ag tellurides, aurostibite, maldonite, and auricupride. In addition, submicroscopic (solid solution) gold, principally in arsenopyrite and pyrite, is also important. The main causes of refractory gold ores are submicroscopic gold, the Au-Ag tellurides, and very fine-grained gold ( 10 m)

    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
