copper iron flotation

iron ore in the world, froth flotation has become increasingly important to process intermediate and lowgrade iron ore in an attempt to meet the rapidly growing demand on the international market. In over half a century's practice in the iron ore industry, froth flotation has been established as an efficient method to remove impurities from iron ore.

copper collector may also be added at this point. The pulp progresses to the flotation cells. The frother and copper collector are usually added to the pulp just before the roughers. Additional copper collector is often added to the scavenger flotation cells and may be added at several other points.

The first countercurrent column flotation device was designed and tested by Town and Flynn in 1919. Crosscurrent pneumatic flotation machines were widely used in industry in 1920's and 1930's, but were later replaced by the impellertype flotation devices in mineral processing plants.

12.3 Primary Copper Smelting

Pine oils, cresylic acid, and longchain alcohols are used for the flotation of copper ores. The flotation concentrates are then dewatered by clarifiion and filtration, resulting in 10 to 15 percent water, 25 percent sulfur, 25 percent iron, and varying quantities of arsenic, antimony, bismuth, cadmium,

copper extraction and purifiion chemguide

Getting copper from chalcopyrite, CuFeS 2. Chalcopyrite (also known as copper pyrites) and similar sulphide ores are the commonest ores of copper. The ores typically contain low percentages of copper and have to be concentrated by, for example, froth flotation before refining.

This is related as: 1) iron sulphide mineral levels are usually much higher than copper concentration, 2) sulphide flotation collectors can float iron sulphides well also, 3) liberation can be an issue making copper and iron separation difficult, and 4) fine particles are often more difficult to separate.

copper, zinc and iron sulphides flotation and depression have been derived, verified and proved. Physicochemical models derived are based on the mechanism of reagents action and represent themselves determined quantitative relationships between concentrations of reagents ions in pulp.

The chemical composition of the ore indies that grade of 2.08 and 5.37 mass% for copper and iron respectively, while carbon was 3.70 mass%. The total organic carbon in the feed was recorded as 2.02 mass%. The presence of these gangue minerals is detrimental to copper and iron recovery during flotation.
