However, when that ore is actually processed through the plant it may well be (and in many cases most likely will be) at another P 80. Additionally, the flotation plant residence time will often be determined solely by the grinding circuit capacity and feed slurry density. In the case of SAG mill – ball mill circuits, the fluctuations in

Sometimes, even if it can not directly select qualified antimony concentrate, it is often selected as a pre-selection operation for antimony flotation operations. Especially when flotation has many difficulties in processing antimony oxide ore at this stage, gravity separation is the main beneficiation method for antimony oxide ore.

The frequent changing of ore properties is a significant issue, which causes difficulty in many flotation plants because good ore resources are eventually exhausted [16,20]. As in many other flotation processes, when the feed grade does not significantly change in gold-antimony flotation, working conditions are relatively stable and the ...

Pre-19th century placer mining operations used mercury to dissolve the gold in crushed ore, making it easier to recover. Later innovations include the MacArthur-Forrest Process and borax flux extraction. However, one of the most interesting methods is froth flotation. Froth flotation works by exploiting the hydrophobic properties of gold molecules.
