ceased. This form of mining usually involves the extraction of secondary gold from placer deposits (alluvial, colluvial or elluvial), which can be liberated and treated using gravity methods. In the Guianas, the most popular form of smallscale gold mining is referred to as "land dredging", a combination of hydraulicking and suction dredging.
gold rushes that led to the settlement of California,Alaska,South Africa, Australia,and the Canadian Klondike—were achieved with minerals providing a major incentive (Rickard,1932).

A feasibility study on the production of gold at a fictitious mine (Moapa mine) in Elko County, Nevada is to be performed. The mine is capable of producing 325,800 tons of highgrade ore per year for 8 years. The deposit contains ounces of gold per ton of highgrade ore and can be acquired at a cost of 10 per ton of ore (cost of mining ore

Gold refining by solvent extraction—the Minataur™ Process by A. Feather*, Sole*, and Bryson* Synopsis The Minataur™ Process (Mintek Alternative Technology for Au Refining) is a novel route for the production of highpurity gold using solvent extraction. Following the successful
Proposed mining projects vary according to the type of metals or materials to be extracted from the earth. The majority of proposed mining projects involve the extraction of ore deposits such as copper, nickel, cobalt, gold, silver, lead, zinc, molybdenum, and platinum. The environmental impacts of largescale mining projects involving
Placer mining is the technique by which gold that has accumulated in a placer deposit is extracted. Placer deposits are composed of relatively loose material that makes tunneling difficult, and so most means of extracting it involve the use of water or dredging.
