The process of extracting copper from copper ore varies according to the type of ore and the desired purity of the final product. Each process consists of several steps in which unwanted materials are physically or chemically removed, and the concentration of copper is progressively increased.

The Fort Knox Gold Mine is an open pit gold mine in the Fairbanks mining district of Alaska.It is owned and operated by Toronto based Kinross Gold.Originally staked in 1913, the property sat idle until being restaked in 1980, and purchased by Amax Gold, who brought the mine into production. Ownership transferred to Kinross Gold following its 1998 merger with Amax.

Tailings Dam Construction Design of slime is likely to slide and cause the dam to break away. The procedure usually adopted in such cases is to separate the tailing into coarse sand and fines in a classifier, and to use the coarse product to build up the wall ; the remainder of the pulp is discharged into the interior of the dam.

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 ...

Tailings are the materials left over after the process of separating the valuable fraction from the uneconomic fraction of an ore. Tailings are distinct from overburden, which is the waste rock or other material that overlies an ore or mineral body and is displaced during mining without being processed.

Mineral processing wastes are referred to in the Resource Conservation and Recovery Act (RCRA) as wastes that are generated during the extraction and beneficiation of ores and minerals. These wastes can be subdivided into a number of categories: waste rock, mill .

The general process of multiple subaerial deposition is as follows (modified from (Ulrich, East et al. 2000)): Tailings are discharged onto a portion of the gently sloping beach creating braided flows towards the supernatant pond.

Conventional Thickeners are generally incorporated in heavy duty applications when the underflow density is high and substantial torques are required to convey the settled solids from the periphery to the central outlet for pumping away.

The Gold Jig or Mineral Jigs are important of all types of alluvial gold concentrating device among all gravity separation methods; they are also the most complex and the practice of jigging in mineral processing is often viewed as an art rather than a science. Gold jigging has been referred to as being probably the most complex gravity operation because of its continuously varying hydrodynamics.

The slime residue from the absorption section can be pumped either to the tailings dam or the backfill plant. Finally, the gold bearing carbon is removed from the absorption section and pumped to the elution circuit to remove the gold from the carbon. The gold in solution is plated out in the electrowinning circuit, where it is smelted.

In all ore dressing and milling Operations, including flotation, cyanidation, gravity concentration, and amalgamation, the Working Principle is to crush and grind, often with rob mill & ball mills, the ore in order to liberate the minerals. In the chemical and process industries, grinding is an important step in preparing raw materials for subsequent treatment.
