摘要
通过对从硫化锑矿渣中回收硫的实验研究，找出了正交试验的最佳条件：浸取剂I^＊与矿渣的液固比为10：1（mL／g）；加热时间15min，浸取加热温度150℃；分离时加热温度130-140℃；急冷温度0℃此时精细硫磺的回收率为96．60％，浸取剂的回收率为92．36％，硫磺的粒度为5．01 μm．硫磺的纯度为98．00％。据此提出了生产精细硫的工艺过程。并为工业化提供了思路。
Based on experiment on fine sulphur recovery from the sulfureted antimony slag, the best conditions for orthogonal experiment was found as follows： liquid-solid rate 10 ： 1 mL/g （leaching solvent to slag）, heating time 15 minutes, leaching heating temperature 150 ℃ ;separation heating temperature 130-140 ℃ and cooling temperature 0 ℃. Under the above conditions, more satisfactory results, such as fine sulphur recovery yield 96.60%, leaching solvent recovery yield 92.36%, the sulphur granularity 5.01 microns and the fine sulphur purity 98.00% were achieved. Meanwhile, the production process flow of fine sulphur was presented; furthermore, it points out a bright way for the industrialized prospect.
