ore processing sulfide

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 Ore Processing « TCB Metals and Refining

Processing Sulfide Ores. Historically, miners have shipped their sulfide concentrates to overseas smelters that have little to no regulations or emissions controls.

Sulfide Ore an overview ScienceDirect Topics

For sulfide ore processing, nickel has to be separated from the iron present in the sulfide concentrate. This is conventionally done in both the smelting and converting stages. To aid iron rejection in the smelting stage, the concentrate is first partially roasted to oxidize the iron sulfide. This is done either in a multiple hearth roaster or in a fluid-bed roaster. During partial roasting
