Recovery of antimony. 500 grams of a lode servantite and senarmontite with 14.0 percent antimony metal was ground wet at 66 percent solids in a laboratory ball mill to pass 65 mesh sieve. In the flotation machine 0.5 pound per ton of sulfuric acid and 0.2 pound per ton of potassium dichromate were added. Conditioned for 5 minutes, then the ...

Selective froth flotation concentration of antimonite ore ...

flotation process is used to concentrate relatively low grade ores. In Zimbabwe antimonite is mined together with lead and arsenic which are regarded as contaminants and hence the need to selectively remove them. We report on the selective concentration of antimonite at the expense of lead and arsenic by use of a depressant. Starting with an containing antimony (5.89%), lead (0.34%) and ...

The recovery of precious metals in the flotation concentrate was poor. The typical gold recovery was less than 25%, and the silver recovery was less than 70%. Antimony recoveries have generally been less than70%, but they are expected to increase when mining is below the surface oxidized zone. Since the silver is associated with the antimony, the silver flotation recovery is also expected to ...

3 Antimony Ore Beneficiation Process - Mining-pedia

Antimony ore can be divided into antimonite, cubismite, antimony ochre, etc. Due to the difference in the nature of the ore, the process used is also different.
