高硫铝土矿浮选脱硫试验研究
Study on Flotation Desulfurization of High Sulfur Bauxite
摘要
Abstract
High sulfur bauxite was taken as the research object and the dosage of adjusters,collectors,and inhibitors were explored afterwards.The results showed that when the addition amounts of sodium carbonate,butyl xanthate,and CMC were 1333,267,and 33 g/t,respectively,the flotation effect was optimal,with an alumina grade of 51.07%and a recovery rate of 97.64%.FTIR analysis revealed that,compared with the o-riginal ore,the addition of butyl xanthate increased the absorption intensity of ester(C—O—C)at1110 cm-1,indicating that butyl xanthate ad-sorbs on high sulfur bauxite,thereby increasing its hydrophobicity and improving flotation performance.关键词
