Separation method for nickel and molybdenum in dressing …
The method combines mechanical ore dressing and low-temperature selective reduction to separate nickel and molybdenum from nickel-molybdenum ore. The nickel-molybdenum ore contains about 2 percent of nickel and about 2 percent of molybdenum, and is a well-known refractory mineral. The invention can obtain two furnace charges by the enrichment and …
