A hydroxamate collector AM28 is used in conjunction with Potassium Amyl Xanthate (PAX) to allow the flotation of the low-grade copper oxide ores from DongChuan Mine. A series of batch laboratory scale flotation tests are conducted for oxide copper minerals to establish the flotation response and the suitability of the collectors. From the rougher flotation tests performed, the …

Copper can be extracted from its ores by reduction. One of the common copper ores, malachite, which is composed of mainly copper carbonate, CuCO3xCu(OH)2, is heated to produce copper oxide with the release of carbon dioxide. CuCO3xCu(OH)2 → 2 CuO + CO2 + H2O The copper oxide is then heated with carbon to get copper. 2 CuO + C → 2 Cu + CO2

All magnetite ores from South Australia produce concentrates with low levels of deleterious elements inclusive of those deposits with relatively coarse grinds in the range 75–125 µm. Magnetite concentrate grades range from 65 to 70% Fe with the variation in iron grade largely sympathetic according to the silica content.

A simpler flotation circuit with lower operating and capital costs for treatment of such copper-gold-pyrite ores with an elevated pyrite head assay was sought in this work. After characterizing the ore, the objective was to apply bulk rougher flotation of both the copper minerals and pyrite for the copper-gold-pyrite ore at natural pH.

Copper ores, for example, typically contain only about 0.5% by weight of the element itself: roughly 200 tons of ore are dug up, moved, crushed, and refined to produce 1 ton of copper. The rare earth element neodymium, which is used in wind turbines, requires mining from 20 to 160 tons of ore to obtain 1 ton.
