G extraction refers to the processes required to extract g from its ores. This may require a combination of comminution, mineral processing, hydrometallurgical, and pyrometallurgical processes to be performed on the ore. G mining from alluvium ores was once achieved by techniques associated with placer mining
Jun 02, 20100183;32;This video was produced by Newmont Mining Corporation and gives a general overview of g mining in Nevada from extraction to reclamation.
G is generally found in two types of deposits lode (vein) or placer deposits; the mining technique used to extract the g depends upon the type of deposit. Once extracted, the g is refined with one of four main processes floatation, amalgamation, cyanidation, or carboninpulp.

G processing, preparation of the ore for use in various products. For thousands of years the word g has connoted something of beauty or value. These images are derived from two properties of g, its colour and its chemical stability. The colour of g is due to the electronic structure of the g
Leaching dissolves the g out of the ore using a chemical solvent. The most common solvent is cyanide, which must be combined with oxygen in a process known as carboninpulp. As the cyanide and oxygen react chemically, g in the pulp dissolves. When workers introduce small carbon grains to
Yet mining the ore is just one stage in a long and complex g mining process. Long before any g 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.
Byproduct g mining. G is also produced by mining in which it is not the principal product. Large copper mines, such as the Bingham Canyon mine in Utah, often recover considerable amounts of g and other metals along with copper. Some sand and gravel pits, such as those around Denver, Colorado, may recover small amounts of g in their wash operations.
