Solvent extraction is generally not used to treat in organics (acids, bases, salts, heavy metals). Solvent extraction processes are not designed to treat particular compounds, and extraction efficiencies and processing rates are lower when there are high concentrations of indigenous organic compounds (humic and tannic acids in soil). Similarly, extraction
Ores are most often oxides; a common example is hematite (Fe 2 O 3). But metals can also be found in sulfides (like ZnS), sulfates (like BaSO 4 ), or carbonateslike what you will work with today. Copper can be found in a couple of different oresone of which is malachite, which contains copper(II) carbonate.

The Hunt method-calls for the direct treatment of the ore with a solution of potassium cyanide to which ammonium hydroxide has been added. The gold is thus extracted together with some copper, and the metals are recovered by electrolytic precipitation, the gold, silver and copper falling to the bottom of the vats as a sludge.
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) electro-deposition of the cobalt and zinc from the strip liquor; and (5) cyanidation of the pressure leach residue to recover gold and silver.

Extraction Converting copper ore to copper metal often involves many steps. First, the ore is crushed into small pieces. Then the crushed pieces are mixed with water to form a slurry, a soup-like mixture of crushed ore and water. The slurry is spun around in large vats with steel balls to crush/the ore to an even finer powder.

A common example of this involves froth flotation. Froth flotation. The ore is first crushed and then treated with something which will bind to the particles of the metal compound that you want and make those particles hydrophobic. "Hydrophobic" literally means "water fearing". In concentrating copper ores, for example, pine oil is often used.
Copper is extracted by the self reduction method. Iron and zinc are both extracted by carbon reduction method from their respective ores. Extraction of Aluminium. Aluminium is extracted electrolytically from bauxite(ore of Aluminium). Bauxite contains hydrated alumina (Al 2 O 3) with some proportions of iron oxide.
PREPARATION OF THE COPPER ORE. This study is limited in general to percolation leaching as it is the most widely used method to give proper contact of solvent with the ore to effect extraction of the copper. One of the important factors in percolation leaching is the size reduction necessary for copper recovery within reasonable time limits.
