HYDROMETALLURGY OF COPPER This process is used for the extraction of copper from low grade sulfide ore. In this process, the crushed and ground ore in bulk about 100,000 tons is exposed to air and water in big tanks. The air in the presence of water gradually oxidizes copper and iron sulphides to their surphides.
The blister copper produced by this process is 99 pure copper. The name blister copper comes from the fact that this final process produces bubbles of sulfur dioxide on the surface of the copper. The blister copper is cast into anodes ready for electrolytic refining. The anode casting turntable moves slowly round.
Sulfide ores. Secondary sulfides those formed by supergene secondary enrichment are resistant to sulfuric ores are a mixture of copper carbonate, sulfate, phosphate, and oxide minerals and secondary sulfide minerals, dominantly chalcocite but other minerals such as digenite can be important in some deposits.. Supergene ores rich in sulfides may be concentrated using
Three different stages are involved when extracting copper from nonsulphide ores. 1. Over a very long time and on a vast scale, the reaction of the ore with a dilute acid such as dilute sulphuric acid produces an extremely dilute copper sulphate by solvent extraction. 2. a. By solvent extraction, the copper sulphate is concentrated.
Galena P b S and zinc blende Z n S are sulphide ores. Cassiterite S n O 2 oxide ore, and Magnetite F e 3 O 4 oxide ore are not sulphide ore. The froth flotation process is used to concentrate sulphide ores, based on preferential wetting properties with frosting agent and water.
Jun 02, 2019 Only sulphide ores are concentrated by froth flotation process because pine oil selectively wets the sulphide ore and hence brings it to the froth. This method is usedfor that metals whose ore gets preferably wetted by the oil and the gangue by the water.
Extract sulfide ore deposits from the ground and place in to the crusher to mince ore from 5 to 50 micrometers. Crushing begins the separation process by preparing the ore to be floated in water. First, the ore is crushed using a gyratory crusher to reduce the ore to 6inch diameter pieces.
Sulfide British English also sulphide is an inorganic anion of sulfur with the chemical formula S 2 or a compound containing one or more S 2 ions. Solutions of sulfide salts are corrosive. Sulfide also refers to chemical compounds large families of inorganic and organic compounds, e.g. lead sulfide and dimethyl sulfide. Hydrogen sulfide H 2 S and bisulfide SH are the conjugate
Conversion of ore into metal a The less reactive metals are extracted by reduction of their oxides by heat alone. For Ex Copper and mercury 1Ore of mercury is cinnabar Mercury oxide is reduced to mercury on heating. HgSs 3 O 2 g gt 2 HgO s 2 SO 2 g 2 Hgs gt 2 Hgl O 2 g 2Ore of copper is copper glance
The Cuprex metal extraction process produces cathodegrade copper using a hydrometallurgical process based on chloride leaching of sulfide ore concentrates. The process incorporates several novel steps to overcome the major problems associated with earlier chloridebased processes, including mild leaching conditions using ferric chloride as leachant and solvent extraction of copper usinga
Principle of operation. Before froth flotation can work, the ore to be treated is reduced to fine particles by crushing and grinding a process known as comminution so that the various minerals exist as physically separate process is known as particle sizes are typically less than 0.1 mm 100 m, but sometimes sizes smaller than 710 m are required.

A procedure was developed for recovering gold, silver, cobalt, copper, and zinc from a massive sulfide ore by a hydrometallurgical process. The procedure consists of 1 oxygen pressure leaching 2 iron, arsenic, and copper removal from the leach solution by precipitation 3 selective extraction of cobalt and zinc from solution 4 electrodeposition of the cobalt and zinc from the strip
Different methods are used to process copper sulfide ores depending on the concentration of copper within the ore higherconcentrated ores can be separated via smelting, while lower
Sulfide Ores. Sulphide ores were mostly created by i the intrusion of molten magma from the mantle into the crust of the earth and ii the formation of localized metalrich sulphide ore bodies by sequential solidification andor hydrothermal leaching and precipitation. From Extractive Metallurgy of Nickel, Cobalt and Platinum Group Metals, 2011
Copper sulphate can be used to separate Copper from Nickel in a sulphide ore or Copper from Fe in Cu Fe sulphide ore. CuSO 4 solution can also be used for removing Pb, Zn, and Fe from copper sulphide ores. In presence of oxidizing agents Ferric ion Ferric sulphate or chloride react with metal sulphides liberating elemental sulphur, e.g.
