Overview of antimony ore beneficiation process: Antimony ore beneficiation methods are mainly hand-selected, re-election, flotation and other methods. Among them, there are more concentrating plants using flotation, followed by hand selection, and fewer re-election plants. A few antimony ore dressing plants use a single flotation process, and most of the antimony ore dressing plants use a combined process, such as a hand-flotation process, a hand-re-selection-flotation process.
There are 25 selected factories in China's state-owned mines, including 22 main concentrates and 3 by-product concentrates. The comprehensive daily processing capacity is 6540t, and the main production selection plant is 4190t. Among them, there are three seats with a daily processing capacity of 1000t or more, two seats of 500t or more, 14 seats of 100t or more, and six of them of 100t or less. Single antimony sulfide ore processing are 11, 3 thioredoxin mixing process of antimony, antimony-containing multi-processing 11 metal ore. The main technical and economic indicators of mineral processing, in 1996 represented the technical and economic indicators of state-owned mining in the 1990s: 锑 锑 ore grade 1.78%, 锑 concentrate grade 24.29%, tailings grade 0.28%, ore dressing metal actual recovery rate 85.24%, workers in kind Labor productivity is 936.82t / (person · a).
The commercial antimony concentrate obtained from the ore beneficiation shall conform to the “锑锑Equality Standard (YB2419-82)†formulated by the national non-ferrous metal industry.
