The ore is treated with dilute sulphuric acid. This trickles slowly through the ore dissolving copper to form copper sulphate. The copper is recovered by electrolytic refining. Advantages of this process are: much less energy is use than in traditional mining no waste gases are given off
It would lift ore production sixfold to produce Mtpa of refined copper from a total resource of almost 80 Mt of contained copper. Measured Resources at the mine at June 2013 were estimated at 1470 Mt grading % Cu, kilograms per tonne (kg/t) U 3 O 8, g/t Au and 2 g/t silver (Ag) for the sulphide ore.
Apr 07, 2015· Lime or Sodium hydroxide (NaOH) are also used as pH modifiers depending on the ore characteristics. Copper sulphate is also used as an activator. Frother selection is also critical and ore specific. The final reagent scheme adopted is however ore specific based on .
The Sulfide Class minerals comprise an economically important class of minerals. Most major ores of important metals such as copper, lead and silver are sulfides. Strong generalities exist in this class. The majority of sulfides are metallic, opaque, generally sectile, soft to .
Dec 27, 2016· Copper salts (copper sulfate) are commonly applied to soil to provide copper. However, these forms of copper readily react with other chemicals in the soil and become unavailable to the plant. In order to protect the copper from reacting with other .
purification of ores such as copper sulfide ore. Electrolysis uses an electrical current to move ions in an electrolyte solution between two electrodes. In copper electrolysis, when a current is applied, positivelycharged copper ions (called cations) leave the anode (positive electrode) and move toward the cathode (negative electrode).
As the acid trickles through the ore, it combines with the copper, producing a weak copper sulfate solution. The socalled 'pregnant' leach solution (or pregnant liquor) is then processed using a hydrometallurgical process known as solvent extraction and electrowinning (or SXEW).

Water is bound to copper sulfate in a specific way. When hydrate is heated, water is being removed from it, just as boiling water from a kettle. Obviously, this process breaks bonds between water molecules and copper sulfate, causing the compound change in color.
