安徽庐江绢云母磁选—漂白试验研究

Experimental Research on Magnetic Separation-Bleaching of Sericite in Lujiang, Anhui Province

安徽庐江绢云母资源丰富,但大部分矿点含铁较高,必须通过除铁漂白处理后才能满足用户对白度的要求。采用高梯度磁选机除铁和化学漂白,可得到白度>85%的精矿,满足塑料、涂料及日化等行业对白度的要求。

There are abundant sericite deposits in Lujiang, Anhui Province, but most of these have higher content of iron. In order to meet user's brightness requirement, magnetic separation and bleaching have to be used. The concentrate with brightness over 85% is obtained by the high-gradient magnetic separation and iron removal by chemical bleaching, which can meet the quality requirements of its application to plastics, coating and cosmetics.
