Geology of Gold Mineralization amp How Gold Deposits are Formed

Where base metals such as copper, lead, and zincare deposited, either in veins or as scattered mineral grains, minor amounts of gold are commonly deposited with them. Deposits of this type are mined for the predominant metals, but the gold is also recovered as a byproduct during processing of the ore. Most byproduct gold has come from porphyry deposits, which are so large that even though

How a Thickener Works Mineral Processing amp Metallurgy

Thickening or dewatering may be defined as the removal of a portion of the liquid from a pulp or slime made up of a mixture of finely divided solids and liquids. The early methods of thickening employed plain, flat bottomed tanks into which the pulp was fed until the tank was full. The solids were then allowed to settle as long as required, the top liquid was decanted, the settled solids were

Guidance about radiation safety on mining operations

All Australian uranium mining and mineral sands operations are required to contain all radioactive wastes, in mined out pits or in engineered tailings dams. Mineral sands operations are usually required to either bury the radioactive monazite tails in the base of worked out pits, or to dilute them with non radioactive tails and place in the pits, or in dredge ponds, during backfilling.
