It mainly originates from the smelting and refining of copper sulfide ore, especially chalcopyrite (CuFeS 2). Because of the low copper grade in primary copper-bearing ores, flotation is required to enrich copper-bearing minerals to obtain copper concentrates that satisfy the smelting standards (Han et al., 2020a).flotation, in mineral processing, method used to separate and concentrate ores by altering their surfaces to a hydrophobic or hydrophilic condition—that is, the surfaces are either repelled or attracted by Flotation Mineral Processing, Separation

Porphyry copper deposits are important sources of copper and typically processed by flotation to produce copper concentrates. As mining areas become deeper, the amounts of impurities, such as sphalerite, can be Copper ore usually contains about 0.5 to 2% copper that occurs in the form of disseminated and stringers. The run of mine ore is reduced from 150 mm to 25 mm size in Jaw and Cone crushers. The crushed ore is grinded in ball mills to −74 μm size. The ore is processed by froth flotation comprising rougher and scavenger cells.Copper Ore an overview ScienceDirect Topics

Pyrite depression in the flotation of copper ores is difficult due to the activation of Cu2+ ions on pyrite surface. In this study, the radical chain reaction involving the redox cycling of Cu(I/II) induced by sodium metabisulphite (MBS) was exploited to selectively depress the flotation of copper-activated pyrite at pH 8.0. Electrochemical Poor floatability of oxidized copper ores has been widely known for a number of years (e.g. [6-10]. Generally, for the processing of oxide copper ores, two methods are used: 1) hydrometallurgical, and; 2) flotation, but for a long time the hydrometallurgical method (SX-EW) has dominated the technique of processing oxidized PAPER OPEN ACCESS

The MLA results were then used to calculate the recovery of each mineral in each copper-molybdenum ores. As we used five types of copper-molybdenum ores, the analytical work would be enormous and time-consuming.The search for effective reagents for the flotation of non-ferrous metals from mineral raw materials is an actual problem.

Flotation of Copper Ores . By Donald I. Bleiwas . Open-File Report 2012–1089 . U.S. Department of the Interior . U.S. Geological Survey. This report provides a perspective on the amount of water used by a conventional copper flotation plant, including the makeup water required to compensate for water losses.Different milling conditions, such as wet or dry, and use of different grinding media have a great impact on the flotation performance of sulphide minerals. In the present study, the effects of wet and dry grinding and the use of different grinding media, such as mild steel (MS) and stainless steel (SS), were investigated on a Cu-sulphide ore.

A Copper Flotation Flowsheet. Because the copper in this type of ore usually assays only plus or minus 1% copper, the porphyry copper operations must be relatively large in order to be commercial. The flowsheet in this study illustrates a typical 3,000 ton per day operation. In general most operations of this type have two or more Since flotation is widely used to separate the values In this case, the hypogene ore carried a range of copper sulphides including chalcopyrite (26.3%), bornite (50.9%), and and their chemically modified versions.

In the rougher copper-lead flotation cycle the optimum pulp density of 30% is established. At this pulp density the use of combined microflotation allows to increase the total extraction of copper (from 83.79% to 92.0%) and lead (from 84.16% to 92.72)without disturbing the selection of sulfide minerals.Flotation is a common mineral processing method used to upgrade copper sulfide ores; in this method, copper sulfide mineral particles are concentrated in froth, and associated gangue minerals areAgglomeration–Flotation of Finely Ground Chalcopyrite Using
