Effect of Grinding Environment on Galena Flotation

2016-6-11  Galena is the main mineral of lead and it is commonly associated with other sulphide minerals, such as pyrite (FeS 2), chalcopyrite (CuFeS 2) and sphalerite (ZnS). Guy and Trahar (1984) reported that the floatability of galena is dependent upon the grinding environment [1] and galena

2010-10-1  Formation of metal hydroxides on mineral surfaces is proposed to result in a reducing grinding environment due to galvanic interactions between minerals and grinding media. Complexing with EDTA solution has been used as a way to analyze these species, such as iron hydroxides. The amount of EDTA-soluble iron from tests was determined (Fig. 4
