Handling-re-election-flotation-heavy medium selection of sulfide-oxidation mixed antimony ore in tin mine
The main luminance tin mine ore and minerals antimony yellow, about half and half, by the process selected for the hand - reselection - Flotation - dense medium is selected from (below). The processing capacity of hand selection and heavy and flotation accounted for 55.9% and 44.1%, respectively. The mixed concentrate was re-elected for grinding once, together with the flocculating strontium sulfide concentrate, sent to the ¢12m concentration machine for dehydration, dried and made. The pellets are sent to the smelter for treatment, and the production indicators for the tin mine north plant are listed in the table below.
