Uniform design is used in the experiment in which factors investigated include initial pH value, liquid arrangement intensity and average particle size of ore. Regression analysis of desulfurization rates by liquid shows that the liquid arrangement intensity influences the desulfurization most, the ore particle size less, and the pH value the least. Liquid arrangement intensity and pH are positively correlated with the desulfurization rate, but ore particle size negatively. The result of SEM shows that the sulfur content of the ore surface is reduced to 15% or less from about 43%. The ore flammability is lower, with the surface desulfurization rate being 65%., authors=AI Chunming, WU Aixiang, WANG Hongjiang, authorsList=AI Chunming, WU Aixiang, WANG Hongjiang, authorCompany=Key

值、布液强度和矿石平均粒径3 个因素对脱硫效果的影响。脱硫实验结果表明,布液强度对矿石脱硫率的影响最大,矿石粒径次之,pH 值最小。对脱硫率进行回归分析,结果表明,布液强度、pH 值与脱硫率为正相关,矿石粒径与脱硫率为负相关,脱硫率预测最大值可达到19.66%。此外,电镜扫描显示,细菌脱硫作用使矿石表面由致密变为疏松,矿石表面的硫含量由43%左右降低至15%左右,表面脱硫率为65%,矿石的可燃性降低。, authors=艾纯明, 吴爱祥, 王洪江, authorsList=艾纯明, 吴爱祥, 王洪江,
