nihil molestiae consequatur

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.

pyrite in iron mine

Iron oxyhydroxide coating of pyrite for acid mine

2009-9-1  Because of its abundance, pyrite is commonly the main source of acid production in mine wastes. The pH of freshly exposed pyrite bearing rocks is usually greater than four so that dissolved O 2 (DO) is the principal pyrite oxidant and the rate of acid production is relatively low (Fig. 1, py–DO reaction in Table 1) (Williamson and Rimstidt, 1994). However, if this acid is not neutralized as quickly as it is

What is Pyrite? Pyrite is a brass-yellow mineral with a bright metallic luster.It has a chemical composition of iron sulfide (FeS 2) and is the most common sulfide mineral.It forms at high and low temperatures and occurs, usually in small quantities, in igneous, metamorphic, and sedimentary rocks worldwide.
