Extraction of Copper and Zinc | Chemistry, Class 12 ...

Copper is mostly extracted from the sulphide ore, copper pyrites, by means of the following two processes: i-Smelting process ii-Hydrometallurgical process SMELTING PROCESS Modern copper metallurgy is based on the smelting process. Following steps are involved: i. CONCENTRATION OF THE ORE The finely powdered ore is concentrated by froth flotation process

  • Extraction Of Copper | Mining, Concentration, Smelting

    The concentration of ore is required and it is done by the method. Concentration of Ore: The ore is crushed into a fine powder and a suspension is created in water. To this are added, Collectors and Froth Stabilizers. Collectors pine oils, fatty acids etc increase the non-wettability of the metal part of the ore and allow it to form froth and Froth Stabilizers cresols, aniline etc sustain the froth
