preconcentration for low grade copper ore

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.

Pre-concentration of a low-grade sulfidic copper ore

2000-1-1  Sink and float tests were carried out on low-grade copper ore crushed to <9 mm and classified before beneficiation. In this way, it was established that 45% of the ore was discarded with 0.04% Cu and a loss of metal recovery of only 6.1%. The pre-concentrate obtained in this manner had a grade of 0.48% Cu and a recovery of 93.8%.
