Features and Flotation of Complex Cu-Pb-Zn Sulphides

Problems arising during flotation of complex Cu-Pb-Zn sulphide ores are in general of geological origin. The features of these ores are reviewed, stressing that mineralogical studies extending to process mineralogy are prerequisite for a consistent flotation process. Some examples affecting flotation

Research on Adsorption and Flotation Properties of Herbal

In world mineral processing practice, herbal agents (starch, dextrin, quebracho, etc.) are used for depression of oxidized gangue minerals in sul fide flotation. Tannin is applied as a depressant of calcite and dolomite in the flotation of scheelite and fluorite (Shubov et al., 1990). Organic poly-mers (guar gum and CMC) that incorporate phe -

years. During that time archaeological methods of fine-screening and flotation changed dramatically. For example, the Wicken Bonhunt faunal remains, which were collected between 1971 and 1973, were hand collected without the benefit of fine-sieving. Flotation was carried out at West Stow only during the final 1972 season; the remainder of the fauna

Bioleaching: metal solubilization by microorganisms

Abstract. Bioleaching is a simple and effective technology for metal extraction from low-grade ores and mineral concentrates. Metal recovery from sulfide minerals is based on the activity of chemolithotrophic bacteria, mainly Thiobacillus ferrooxidans and T. thiooxidans, which convert insoluble metal sulfides into soluble metal sulfates.Non-sulfide ores and minerals can be treated by
