贵州某黑色页岩硫的迁出实验研究

Abstract

Abstract: According to the characteristics，such as a certain sulfur contained and complex nature，of the black shale in Guizhou Province，considering the impact of sulfur emigration from it on the environment，acid leaching experiments were conducted.Research found when particle fineness of black shale was at 150～375 μm，concentration of hydrochloric acid was 1.2 mol/L，leaching time was 4 h，leaching pulp liquid-solid volume mass ratio was 4 mL/g，extraction temperature was 30 ℃， and stirring intensity was 250 r/min，the sulfur′s leaching rate was as high as 23.73%，and at this time it had greater influence on the surrounding environment.

Key words: black shale, sulfur, acid leaching, emigration
