阐述了用γＦｅ２Ｏ３·Ｈ２Ｏ及ＦｅＯ（ＯＨ）处理煤系硫铁矿的方法及最佳条件。试验表明在γＦｅ２Ｏ３·Ｈ２Ｏ的量为６０ｇ／Ｌ，溶液酸度在ｐＨ０５～１０范围内，通入０３Ｌ／ｍｉｎ的空气并加热至沸的情况下，对１０ｇ／Ｌ硫铁矿反应１６ｈ，硫铁矿硫脱除率可达９０％以上，比单纯用ＦｅＣｌ３氧化硫铁矿快３ｈ以上。
The method and the optimum conditions of coal pyrite treated with γFe2O3 · H2O and FeO (OH) are described. Experiments show that the amount of γ Fe2O3 · H2O 60g / L, the solution acidity in the pH range 0 5 ~ 1 0, through the 0 3L / min of air and heated to a boil, the case of 10g / L sulfur Iron ore reaction 16h, pyrite sulfur removal rate of up to 90% more than simple oxidation of pyrite with iron oxide faster than 3h.
