河南省内乡县硅线石选矿及除铁研究

Study on Beneficiation and Iron-removal of Sillimanite from Neixiang County,Henan Province

介绍了河南内乡硅线石浮选工艺、除铁效果及精矿主要理化指标 ,指出对浮选精矿采用磁选进一步除铁 ,效果比酸浸要好。

This paper introduced beneficiating technique,iron removing result of sillimanite ore from Neixiang County,Henan province,illustrated the main physicochemical indexes of flotating concentrate,and pointed out that the further iron removing result of flotating concentrate by magnetic separation will be better than its acid bleaching.
