HOW TO EXTRACT COPPER FROM ROCK ORE / COPPER EXTRACTION PROCESS FLOW SHEET

The commonest ore used in the extraction of copper is Chalcopyrite (CuFeS2) also known as Copper Pyrites and other such sulfides. The percentage of copper in the actual ore is too low for direct extraction of copper to be viable. The concentration of ore is required and it is done by the Froth Flotation method.

THE STEPS OF CONCENTRATION OF COPPER ORE: 

The ore is crushed into a fine powder and a suspension is created in the 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. The oil wets the metal and the water wets the gangue. Paddles and air constantly stir up the suspension to create the froth. This frothy metal is skimmed off the top and dried to recover the metal.
