concentration of copper project ores

Copper extraction - Wikipedia

However, as the concentration of copper in the ore bodies decreased, the energy costs of smelting the whole ore also became prohibitive, and it became necessary to concentrate the ores first. Initial concentration techniques included hand-sorting and gravity concentration. They resulted in high losses of copper

Pre-concentration of copper ores by high voltage pulses ...

01/08/2015  Burns and Grimes (1986) reported pre-concentration of a copper ore by screening at the Bougainville copper plant operation. Based on detailed recovery-size-yield data collected from the Newcrest Telfer operation, Bowman and Bearman (2014) reported a potential application of coarse waste rejection through size-based separation for copper production.

01/08/2015  Nevertheless, despite the reverse grade trend, pre-concentration of this ore by electrical pulses was still achieved, with 90.6% copper retained in the surface breakage component (40.2% mass) and 9.4% copper distributed in the body breakage component (59.8% mass). The key question in this case is that whether or not the reverse trend of the valuable minerals containing in the surface

LABORATORY CONCENTRATION OF VARIOUS ALASKA COPPER

Two samples of arsenic-bearing, low-grade copper ore were obtained from the Golden Zone mine near Colorado Station, Alaska (fig. 1, item 3). By selective flot-ation of 0.97-percent Cu ore from the upper level, 82 percent of the copper was re- covered in a concentrate that assayed 26.6 percent Cu; similar treatment of 0.24-percent Cu ore from the lower level recovered 67 percent of the copper ...

Eliminating Copper from Gold Ore

When reviewing Methods of Eliminating Copper from Gold Ores we see that several methods have been suggested to eliminate copper from ores prior to cyanidation. Preliminary extraction of the copper with sulphuric or sulphurous acids may be applicable to ores containing oxidized copper minerals such as malachite, azurite and chrysocolla but these acids have but little effect on sulphide copper ...

Copper ores - Danafloat

A typical copper sulphide ore contains various levels of iron sulphide types that generally include pyrite (FeS2) and pyrrhotite (Fe1-xS). Often gold and silver are present which may either be associated with the sulphides or are free. The gangue particles can consist of a range of silicate minerals from quartz to talc and clays. Carbonate mineral gangue can also be present. When liberated ...

Concentration of ores - Metallurgy Chemistry

Concentration of ores. Generally, the ores are associated with non-metallic impurities, rocky materials and siliceous matter which are collectively known as gangue. The preliminary step in metallurgical process is removal of these impurities. This removal process is known as concentration of ore. It increases the concentration of the metal of interest or its compound in the ore. Several ...
