Some basic properties Concerning albanite,the principle of the removal

本文叙述了高硫锰矿的基本性质、焙烧脱硫的原理、试验工艺流程、工业诚验结果、产品性质及成本核算等。以烟煤为燃料,在强氧化气氛中,在1150℃左右温度条件下,矿石经过回转窑焙烧后达到焙烧、烧结扣脱硫的目的。获得产品质量良好,是冶炼锰铁合金的优质原料。工业试验证明,处理高硫锰矿的这一新工艺,技术可靠,经济效益显著,将在我国锰矿生产中起到积极作用。

Zinc oxide was prepared through digesting roasted,desulphurized zinc concentrate with industrial sulfuric acid followed by a series of steps of de-impurity. The purity of zinc oxide product was 99.7%. Various items of technical index was consistent with the standard of product. Overall yield of zinc was more than 87%.

Multi-hearth furnace and rotary kiln are commonly employed in the world for the roasting of tin concentrate to remove sulphur, arsenic and other impurities.However,the fluidized bed roasting technology and the structure of the furnace are described in this paper.Laboratory experiments and industrial tests with a 5m2 fluidized bed furnace were conducted.The problem in the S and As removal, which requires different atmospheres,was solved in one furnace.The difficulties caused by fine particles and wide size distributions of the tin concentrate during fluidized bed roasting were also overcome. Removal of 98.84% S and 85.47% As can be reached.The recovery of tin during the roasting is 99.28%. The unit capacity is 11.92t/m2d. The coal consumption is 3.5%. This technology has reached the world advanced level and has been put into operation by large tin smelters.

锡精矿焙烧脱硫、砷等杂质,世界上普遍采用多膛炉和回转窑。本文研究锡精矿沸腾焙烧工艺和炉型结构,进行了比较系统的试验室试验和5m2沸腾炉焙烧工业试验,解决了在一台沸腾炉内脱硫、脱砷要求的不同气氛和锡精矿因粒度细、粒级宽给沸腾焙烧带来的困难。研究结果(平均值):脱硫效率94.84%,脱砷效率85.47%,炉床能力11.92t/m2·d,锡在焙砂中的直收率99.28%,煤耗3.5%。技术经济指标处于世界先进水平。研究成果已应用于大型炼锡厂的建设和生产。
