BACTERIAL LEACHING OF COPPER FROM WASTE OF ENRICHMENT OF COPPER ORE
Journal Title: Afyon Kocatepe Üniversitesi Uluslararası Mühendislik Teknolojileri ve Uygulamalı Bilimler Dergisi - Year 2018, Vol 1, Issue 1
Abstract
In poor and complex ores processing thousands and even millions tons of valuable metals are lost in the waste form. Bacterial leaching of metals reduces these losses. The basis of this process is made by oxidation of the sulphidic minerals which are contained in ores thionew bacteria. Thus metals from an insoluble sulphidic form pass into sulfates, well soluble in water. From sulphatic solutions metals are extracted by sedimentation, extraction, sorption. Existence of a biological product on the basis of the bacterial strains which are actively leaching copper is the main condition of a possibility of extraction of metals from enrichment waste.
