Melting of crude antimony in the low-tonnage production

precipitation smelting of antimony ore is based on the great affinity of sulfur and oxygen to iron, rather than to antimony. The main purpose of meltings the antimony raw materials is the transfer of the main substance of ore – antimony in a less contaminated by iron metal. Durcrudeing melting, sulfides react with iron,
