CN110453066A 一种高铁铝土矿浮选脱硅-深度还原熔炼的方法 无效 - 驳回

一种高铁铝土矿浮选脱硅-深度还原熔炼的方法
摘要：
本发明公开了一种高铁铝土矿浮选脱硅-深度还原熔炼的方法。本发明首先通过对高铁铝土矿进行破碎和磨矿，然后采用阳离子反浮选工艺对高铁铝土矿进行脱硅处理，再进行预还原焙烧和深度还原，最终高铁铝土矿中的铁铝得到有效回收，铁回收率>95％,氧化铝浸出率>85％。
摘要（英）：

The invention discloses a high iron bauxite flotation silicon removal-deep reduction smelting method. The high iron bauxite flotation silicon removal-deep reduction smelting method includes: first performing smashing and ore grinding on high iron bauxite, then using the cation reverse flotation technology for performing silicon removal treatment on the high iron bauxite, and then performing prereduction roasting and deep reduction, and finally effectively recycling iron and aluminum in the high iron bauxite. By using the high iron bauxite flotation silicon removal-deep reduction smelting method, recovery rate of the iron is larger than 95%, and leaching rate of aluminum oxide is larger than 85%.
