Introduction of antimony ore processing:
The antimony ore beneficiation methods,should be based on the type of ore,mineral composition,mineral structure and embedded Pot and other physical and chemical properties as the basic conditions to select, you should also consider a price component content and meet the requirements of the antimony metallurgical technology and ultimatelyeconomic and other factors.
Antimony ore beneficiation methods, hand-selected, gravity concentration, heavy media separation, flotation:
Hand-selected to reduce the beneficiation production costs and energy consumption,so it is widely used in our country. According to statistics: China now produces 18 major antimony concentrator, 15 hand-selected job, accounting for 83.3%, of which four single antimony sulfide ore processing plant, four sulfide - mixed antimony oxide ore processing plant, antimony-containing complex multi-metal ore processing plant 7.
Gravity concentration:
Gravity concentration for the the most antimony ore processing plant are applicable, because antimony minerals belong to the large density, a coarse granularity mineral, easy re-election method gangue separation.
In short, regardless of a single antimony sulfide ore or sulfide (the mixed oxidation antimony ore, have better gravity concentration. And low cost of gravity concentration, but also in the coarser particle size range, sub-elected by a large number of qualified coarse concentrate and discard large quantities of gangue, therefore, gravity concentration is still willing to adopt the beneficiation method is antimony beneficiation workers today.Heavy media beneficiation
Heavy media beneficiation difficulty is the choice of the weighting agent,media preparation and recovery. A substance that is used as aggravating agent practice: the grinding wheel corundum waste (ferrosilicon) is ideal.
Flotation process is the main antimony ore processing method:
Minerals, most of them are easy floating antimony sulfide mineral flotation ore crystallographic sites. Stibnite often precede lead salts as activators also useful copper salt or a combination of lead salts copper salt, then collector flotation.
