Copper is also used in industrial equipment and machinery, consumer products and a variety of other electrical and electronic applications and is also used to make brass. Copper substitutes include aluminum, plastics, stainless steel and fiber optics. Refined, or cathode, copper is also an internationally traded commodity. Copper Supply.
Cleaner tailings may be conveniently removed at any point in the circuit. The flowsheet on the reverse side of this page shows one of the many possible cell arrangements used in treating fluorspar ore. Thickening and Filtering Thickening of fluorspar concentrates offers no special problem.

The potential for removing uranium from contaminated groundwater by stimulating the in situ activity of dissimilatory metalreducing microorganisms was evaluated in a uraniumcontaminated aquifer located in Rifle, Colo. Acetate (1 to 3 mM) was injected into the subsurface over a 3month period via an injection gallery composed of 20 injection wells, which was installed upgradient from a series ...
Iron ore mining and processing From the day the Earth was born, the minerals that iron aggregated were distributed unevenly around the world. The iron element exists in nature in the state of a compound, and is particularly present in a state in which iron oxide is present in a particularly large amount.
Source identification using synoptic sampling and principal components analysis. The synoptic sampling and mass balance approach for investigating mine drainage sources and processes was developed as part of the Geological Survey's Toxic Substances Hydrology Program (Bencala et al. 1987; Kimball et .

The Specific Gravity SG is a dimensionless unit defined as the ratio of density of the material to the density of water at a specified temperature. It is common to use the density of water at 4 o C (39 o F) as reference at this point the density of water is at the highest.. Specific gravities SG for common solids and metals can be found in the table below:
The electrowinning circuit will consist of two electrolytic cells each containing a total of twenty two 1m2 stainless steel cathodes. An electrical current will be applied to the cathodes in order to remove the gold from solution where it will become plated onto the surface of the cathodes whilst the barren solution will be returned to the elution circuit for reuse.

The Phase IV expansion will increase ore processing capacity by 85 per cent resulting in an average copper production of 400,000 tonnes per annum (average total production of million tonnes per annum) over the first five years.
Minerun ore is initially crushed and sized in a series of crushers and vibrating screens to approximately minus 5/8 in. Crushed ore is then ground in rod mills and passed through cyclones. The oversize is ground in ball mills, then pumped back to the cyclones to achieve a minus 200 mesh flotation feed.

Anglo American Plc plans to buy back up to 1 billion of shares after the diversified miner reaped bumper profits from its iron ore business, more than offsetting declines in diamond and copper. Anglo is the first to report earnings among the handful of giant miners that produce iron ore and investors have been preparing for big windfalls.
