How phosphate is mined and processed

At the beneficiation plant, the slurry is first run through a screen, which filters out the coarser sand. To separate the phosphate from the . 4 clay, different equipment cause the finer-grained particles to separate from the coarser grains. Finally, a process called flotation is used to separate the phosphate

An overview of chromium removal techniques from tannery

8/9/2020 · Chromium needed for chrome tanning is about 2% or more of the weight of the hides and skins, and the fixation of the chromium is about 60–70% only. Therefore, about 0.5 kg chromium may remain in the used tanning solutions per 1000 kg of hides tanned. This results in material loss as well as disturbance to ecological balance (Thorstensen 1999
