BRIEF ANALYSIS OF BAD EFFECTS OF COAL-SERIES HIGH-CARBON PYRITE IN ACID-MAKING AND ITS DEVELOPED UTILIZATION

This paper describes the bad effects of coal-series high-carbon pyrite in acid-making process, andpoints out that the pyrite can be used comprehensively with HNO3 catalyzing oxidizing and physical method to liftsulfur, reduce carban, increase its utilization value, and protect environment.
