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.

What is Copper Concentrate? Arij Trading

2021-6-20  Although copper occurs naturally in a pure state, it’s primarily mined from chalcopyrite, bornite, and malachite. Copper ore is extracted from the earth, then converted into copper concentrate,

Copper Smelting and Refining Process Pan Pacific

The copper concentrates are fed through the flash smelting furnace with oxygen-enriched air. In the furnace, the concentrates are instantly oxidized, after which they melt and separate by their own reaction heat into copper matte with a grade of 65% and slag consisting of iron oxide, silica, and other compounds. Reaction in the flash smelting furnace
