These the strongest associations are with lead ores. The direct smelting of zinc is difficult due to the low boiling point of the metal. Reduction of zinc oxide to zinc with charcoal requires a temperature of at least 1000°C, however, at this temperature the zinc will be a vapour. Under ordinary circumstances, therefore, the smelting of
Nov 28, 2016· While societies from thousands of years ago used it in the form of stibnite for decoration, in modern times it is used to make semiconductor devices, batteries, low-friction metals, cable sheathing and flame-proofing materials, paint, ceramic enamels, glass and pottery. The traditional method of producing antimony metal is through heat smelting.
Dec 05, 2020· Similar antimony recovery (85%) was obtained from a refractory goldbearing stibnite ore in 5 min with alkaline solution (20 g/L Na 2 S and NaOH) at 80°C by Ubaldini et al. (2000).
