hydrometallurgical methods to process the copperanode slimes for extraction of copper. The decopperized slimes are then enriched in lead, tin, and silver. Many hydrometallurgical processes were reported for extraction of noble metals, among them, cyanide (Hoffmann, 1991; McClincy, 1990) and thiourea leaching (Schulze, 1984).

Extraction of Copper from Copper pyrite. The principal ore of copper is copper pyrite and copper is extracted from this ore. The different steps in extraction of copper are: The ore obtained from mines are broken down into small piece by jaw crusher and then pulverized. The ore being sulphide ore is concentrated by froth floatation process.

· Principles of Metal Extraction: Metals are found in the combined state in ores where they exist as positive ions. During the extraction of metals, the metallic ions must first be reduced to the corresponding metal atoms. This reduction process can be done electrolytically or by thermal or chemical methods.

Iodometric Determination of 2. If excess ammonia is added, copper(II) hydroxide redissolves, forming the deep blue copper(II) ammonia complex, Cu(NH 3) 4. If the excess of ammonia is large, a large quantity of ammonium acetate will be produced later; this may keep the reaction between copper(II) and iodide ions from being complete.
