Abstract：The hematite and pseudo-hematite can be separated effectively from the gan-gue minerals like quartz by using hydroxamic acid as collector.In the treatmentof the rough concentrate from the magnetic separation for iron ore,the resultsfrom direct flotation using AHA and diesel oil,each 71 g/t,are similar to thatfrom reverse flotation using etheramine 106 g/t and H_2SO_4 95 g/t.In weaklybasic pulp,the rough flotation froth collected by AHA and diesel oil was subjec-ted to gravity separation,the total concentrate grade may be up to 65.7% Fe ata recovery about 82%.By floating the lean iron ore with 305 g/t THA,theiron grade may be raised from 27—29 % to 62—64 % Fe for recovery of 88—90%.This means that an increment of 8 % recovery may be gained with no morereagent cost and with better economic benefit in comparison with flotation byusing 1200 g/t oxidized paraffin soap. 收稿日期: 1985-05-18      服务 把本文推荐给朋友 加入引用管理器 E-mail Alert RSS 作者相关文章 周维志 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1985/V21/I5/92 1 刘尧,鞍山铁矿石选矿方案评述,1981． 2 广州有色金属研究院;沈阳药剂厂等“羟肟酸钠浮选氧化铜矿的工业试验,1973． 3 周维志,羟肟酸(盐)在氧化矿浮选中的应用,1981． No related articles found!
