1. Introduction. Antimony is a toxic trace element of increasing concern due to its wide distribution in the environment. Antimony has no known biological function (Filella et al., 2002) and can cause serious adverse effects to living organisms above certain threshold concentrations (Kabata-Pendias and Mukherjee, 2007).It can inhibit culturable …

Antimony ore beneficiation usually adopts gravity separation and flotation as a combined process. The specific gravity of antimony ore is much greater than that of gangue. It is separated by gravity separation to pre-enrich the low-grade ore. The antimony ore, after gravity separation, is then purified by flotation. Process Consult. Introduction.

Antimony mining took place intermittently in Arkansas after the metal's discovery in 1873. Smelting attempts were made first in 1887 but were unsuccessful. The first commercial production was recorded in 1889. Mining activity peaked during World War I when metal prices were high, and sporadic efforts to continue mining ended in 1924 …
