froth flotation of sulfide minerals

Little abrasion wear, Long service life

Based on 30 years of development experience of grinding equipment, LM Heavy Industry produced LUM Series Superfine Vertical Roller Grinding Mill to make ultra-fine powder. The grinding roller doesn't contact with millstone usually, which makes abrasion little and service life longer.

Applications: Superfine dry powder of none-metal ores such as calcite, marble, limestone, coarse whiting, talc, barite and dolomite and so on.

Sulfide Mineral Flotation Maurice C. Fuerstenau, Subhash Chander, and Ronald Woods INTRODUCTION Froth flotation was developed at the Broken Hill mine, Australia, a century ago with the flo- tation of the common sulfide mineral, sphalerite. With this development, billions of tons of worthless rock containing a variety of valuable metals became ore.
