Potassium iron blue of high quality was prepared from pyrite cinders. 以硫鐵礦燒渣為原料製備鉀鐵藍。
The problem of high iron content in zinc concen-trate can not be resolved by single floatation flowsheet because theiron content of sphalerite contaminated in pyrite is high. 由於東升廟硫鐵礦共生閃鋅礦的含鐵量高，所以採用單一浮選流程不能解決鋅精礦鐵雜質含量高的問題。
Pyrrhotite is the most common and abundant iron sulphide mineral in mine wastes worldwide. 磁黃鐵礦是礦山尾礦堆中最為常見且分佈很廣的一種硫化鐵礦物。
The concentrate from a Yunan high sulfur iron ore has a sulfur content that exceeds that specified in the standard due to the pyrrhotite. 雲南某高硫鐵礦石因含磁黃鐵礦而造成精礦含硫超標。
