Get More1. Introduction. Sulfur is an essential element that is widely used in industries (Kutney, 2013).However, the presence of sulfur in mineral concentrates is undesirable because sulfur in metallurgical procedure results in a series of problems (Gallagher et al., 1993), such as production of harmful gases (Liu et al., 2019) and corrosion of steel equipment ().
