heating an ore of antimony

Pnictogen Wikipedia

If the ore contains 45% to 60% antimony by weight, antimony is obtained by heating the ore, also known as liquidation. Ores with more than 60% antimony by weight are chemically displaced with iron shavings from the molten ore, resulting in impure metal. If an oxide ore of antimony contains less than 30% antimony by weight, the ore is reduced in
