Grinding Ores With Sulfur

REMOVAL OF SULFUR AND PHOSPHOROUS FROM IRON …

Sulfur removal can be performed using two main methods: conventional pyrometallurgical (smelting/converting) and hydrometallurgical (flotation/leaching or bioleaching). Reduction of the sulfur content of iron ores is conventionally carried out by flotation after grinding (Weibai, 1983; Changxiang, 2001; Xingwang et al., 2009).
