Using of Roasting Leaching Methods for Copper
Due to copper minerals embedded in this materials at a very fine particle size, and closely symbiosis with iron content and quartz, lead to it difficult to enrichment through ore dressing methods And copper minerals mainly exist in the form of sulfide copper mineral, it can not by leaching method for processing directly, thus put forward a the method of testing a gold ore for treatment with a cyanide solution This is the method that was used in this case for testing the possibility of leaching the copper tailings The ore used,was a low grade copper tailing The are is highly si1icous, which fact is favorable to leaching, as the Si02 does not interfere with the reLeaching copper tailings Froth Flotation Method It is different wetting properties of the surface of the ore and gangue particles This method is especially used Sulphide ores, such as galena zinc blende , or copper pyrites Finely powdered ore is mixed with either pine oil or eucalyptus oil and then mixed with water Air is blown through the mixture with a great forceOccurrence and Extraction of Metals: Extraction of
