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.

Copper production & environmental impact

Tailings are a slurry of fine-grained rock material and process water. Liquid is removed from the tailings slurry in thickeners and the thickened tailings are discharged to the tailings impoundment. Water is usually reclaimed from the thickeners and recirculated to the mill to be used in beneficiation and dust control (Mining Industry Profile: Copper)

Application of copper tailings combined with persulfate

31/08/2020 In this paper, wasted copper tailings (CT) were used to activate persulfate (PS) to degrade azo dye methyl orange (MO). The results show that a large amount of FeS 2 contained in CT can slowly release Fe 2+ in the aqueous solution to activate PS to generate reactive oxygen species to degrade MO. When the dosage of CT and PS was 2 g/L and 3 mM respectively, the

Lessons From the Most Toxic Open Pit Copper Mine in the World

28/11/2016 What makes the tailings ponds so dangerous is the fact that the copper extraction process requires that the ore be ground up into a fine powder to which is added water and chemicals, and then, after the copper has been extracted, the semiliquid slurry containing a multitude of dangerous chemicals and metals is pumped through a pipeline to a waste pond.
