Froth flotation. All primary sulfide ores of copper sulfides, and most concentrates of secondary copper sulfides (being chalcocite ), are subjected to smelting. Some vat leach or pressure leach processes exist to solubilise chalcocite concentrates and produce copper cathode from the resulting leachate solution,

Handbook of Flotation Reagents Chemistry, Theory and
In flotation of gold containing base metal ores, a number of modifiers normally used for selective flotation of copper lead, lead zinc, and copper lead zinc have a negative effect on the floatability of gold. Such modifiers include ZnSO4183;7H2O, SO2, Na2S2O5, and cyanide when added in excessive amounts.

The ore is mined from an open pit, crushed, and fed to ten ball mills. The concentrator is divided into two parallel comminution flotation sections, so that five ball mills feed each flotation section. Both sections consist of three bulk copper and molybdenum rougher flotation lines, and the rougher concentrate is transferred to a regrinding stage.
If iron is present in sulphide form, then a xanthate reagent is necessary to properly activate and float it. The pulp is usually regulated with sulfuric acid to give a pH of 2.5 3.0 for best results through flotation. A low reagent cost is necessary because of the low value of the clean sand product.

Copper Mining and Processing Processing of Copper Ores
The leaching reagent (dilute sulfuric acid) is sprayed through sprinklers on top of the heap pile and allowed to trickle down through the heap, where it dissolves the copper from the ore. The resulting pregnant leach solution of sulfuric acid and copper sulfate is collected in a small pool.

Various process chemicals are used in the froth flotation of metallic ore of uranium, copper, zinc, lead, and iron. The flotation chemicals are mainly Isooctyl Acid Phosphate, Sodium Isopropyl Xanthate and Potassium Amyl Xanthate as conditioner and collector, MIBC as frothers, and sodium cyanide and copper sulfate as depressors.
Copper is a chemical element with symbol Cu (from Latin cuprum) and atomic number 29. It is a soft, malleable, and ductile metal with very high thermal and electrical conductivity.A freshly exposed surface of pure copper has a pinkish orange color.Copper is used as a conductor of heat and electricity, as a building material, and as a constituent of various metal alloys, such as sterling
Copper Flotation Mineral Processing amp; Metallurgy
Flotation of Copper Ores. When the ore is free from pyrite, the function of the lime, whatever the reagent mixture, is to precipitate dissolved salts and to maintain the alkalinity of the pulp at the value which has been found to give the best results ; soda ash is seldom employed for this purpose.
Introduction to Mineral Processing Chevron Phillips Chemical
Lead/Zinc Ore. The main difference in lead/zinc flotation is that zinc is usually depressed while lead (and copper) is floated. The tailing from the lead flotation circuit is the feed to the zinc circuit. The ability to selectively float the separate minerals depends on the ore, the chemicals, and other factors.
A series of flotation tests was run to determine the best grind and reagent combination for treatment of the ore. Although good recoveries of copper were ob tained by rougher flotation of ore ground to minus 48 or 65 mesh, difficulty was experienced in cleaning the rougher concentrate. Partial oxidation of the ore
Flotation experiment research on a polymetallic sulfide ore of
The most valuable elements in a polymetallic sulfide ore in the Shanxi province are copper, lead, zinc, gold and silver, and the main metal minerals are galena, sphalerite, chalcopyrite, pyrite, and so on. Microscopic images show that gold and silver were not observed in the ore.
Flotation of Copper Ores Mineral Processing amp; Metallurgy
Flotation of Copper Ores. Treating coarser material or ores that contain a large percentage of heavy gangue (such as in the Coeur dAlene), it has been found advantageous to increase this to as much as 4189; in. per foot to prevent the blanketing of the porous medium by coarse sand collecting on the bottom.
Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic. This is used in mineral processing, paper recycling and waste water treatment industries. Historically this was first used in the mining industry, where it was one of the great enabling technologies of the 20th century.
FROTH FLOTATION RECENT TRENDS Flotation of Sulphide
History of Sulphide ore flotation dates back to beginning of 20th century. Sulphide ores are major sources of base metals like Copper, Lead, Zinc, Nickel, Cobalt etc. Beneficiation of these base metal sulphide minerals is predominating through froth flotation technique. This technology has acclaimed importance as a versatile process for
