Lead-zinc ore usually exists in the form of sulfide ores, such as sphalerite and galena. Flotation is the most commonly used method.. The lead-zinc ore processing solution is adjusted and used in combination according to ore characteristics, metal grade and other factors, such as gravity-flotation, magnetic-flotation, and gravity-magnetic-flotation, in order to achieve the best …
Rotary scrubber. The rotary scrubber is used to clean and screen ore with large mud content but is challenging to wash. The long washing cylinder allows the material to stay inside for a long time, with a vigorous scrubbing ability. The high-pressure washing water washes the inner wall, thoroughly and powerfully dispersing the material completely.
In this paper, the process of solid-state metalized reduction and magnetic separation was investigated for preparation of nickel–iron concentrate from a low-grade laterite nickel ore. The effects of reduction temperature, reduction time, amount of dosages, and magnetic field strength on grades and recoveries of nickel and iron were studied. The results showed …
It is used to select ores containing less copper than nickel, and the resulting copper-nickel mixed concentrate is directly smelted into high-ice nickel.
