Low-grade tin concentrate and low-tin complex material-Yunxi Sanye treatment process

November 16, 2022

Cloud tin Metallurgical established in November 1976, is the rule of the use of gold chloride treatment process polymetallic tin lean Refractory Ore, comprehensive recycling tin, lead, zinc, tungsten, bismuth, silver, indium, cadmium and iron, which are The smelter of valence metal is the main test plant of Yunxi Company which uses high temperature chlorination roasting process to treat high-iron refractory tin ore. The refractory tin ore in the plant is 1.5%-2% tin, divided into high-iron (>45% Fe) refractory tin ore and low-iron refractory tin. The chemical composition is shown in the table below. The process of chlorination of the blast furnace used in the treatment of low-iron refractory tin ore is shown in the following figure.
