Removing the goldbearing 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.
Gold extraction Gold mining •Panning )لصفلا( – sand and gravel (ىصح) containing gold is shaken around with water in a pan. Gold is much denser than rock, so quickly settles to the bottom of the pan. 4 •Hard rock mining – used to extract gold encased in rock. Either open pit mining or underground mining.
This book is an amazingly detailed exposition of gold concentration and extraction. Many books are long on the theory and very thin on the engineering issues involved. Other books are enhanced process diagrams and cookbooks and give little theory.

Gold extraction refers to the processes required to extract gold from its may require a combination of comminution, mineral processing, hydrometallurgical, and pyrometallurgical processes to be performed on the ore.. Gold mining from alluvium ores was once achieved by techniques associated with placer mining such as simple gold panning and sluicing, resulting in direct recovery of ...
Gold in the form of telluride is usually much more difficult to dissolve than metallic gold. Special procedures and processes have been used for the extraction of gold from ores containing tellurides. Metallic gold is frequently associated very intimately with such minerals as pyrite and arsenopyrite.
