2017-8-27 · A procedure for the separation and recovery of antimony from this stibnite concentrate by electrowin-ning was studied (Figure 1). The process for the recovery of antimony from this concentrate was carried out in the following three main stages: antimony pentachloride circular leaching, puriﬁion, and mem-brane electrowinning.
2007-5-4 · The four-step extraction procedure by Wenzel et al. gives a more detailed pattern of the binding of antimony and arsenic. This procedure was found to be a suitable scheme for evaluating the possible mobilization processes from the samples contaminated by ore processing waste, especially by change through other ions or under reducing conditions.

1994-3-1 · Antimony is often present in the material to be treated in both its +3 (trivalent) and +5 (pentavalent) valence states. It is desirable during leaching to obtain an antimony product in its +5 state rather than its +3 state (i.e., as sodium thioantimonate rather than sodium thioantimonite).
The metalliferous ore mining and smelting industries have been the main source of heavy metal pollution over the past hundreds of years (Aleksander-Kwaterczak and Helios-Rybicka, 2009, Douay et al., 2007).
