How to Remove Pyrite from Coal - 911 Metallurgist

Stage grinding of this coal improved the dry separation considerably, although the reject portion was higher. The results in table 11 and figure 16 show that about 65 pct of the pyritic sulfur was removed after three 15-min stages and one 30-min grinding stage. This pyritic sulfur removal amounted to nearly 90 pct of the available pyritic sulfur.
