The massive antimony concentrate tungsten obtained by manual separation contains more than 7% antimony, which can then be smelted to produce raw antimony. It should be noted that in order to improve the efficiency of manual separation, the ore should be washed to remove sludge impurities before beneficiation.

Tin concentrate is smelted to resmelted slag for additional tin recovery. The furnace charge consists of tin ore (cassiterite), a carbon reducing agent (coke), and limestone and silica fluxes. The quantity of coke and flux is carefully adjusted so as to produce an almost neutral slag (ie, acid-to-base ratio is 1). The smelting takes 10–12 h ...
