本文介绍了用高梯度磁选或强磁选选别花垣锰矿南区矿样取得的进展。所得的一级锰精矿含锰28.86%(烧后42.80％),锰回收率22.01％,P/Mn0.0037;二级锰精矿含锰24.08％(烧后35.30％),锰回收率58.86%,P/Mn0.0069。
This article describes the progress made in the selection of ore samples from the southern part of Huayuan manganese ore by high gradient magnetic separation or strong magnetic separation. The obtained primary manganese concentrate contained 28.86% manganese (42.80% after burning), the manganese recovery rate was 22.01% and the P / Mn 0.0037; the secondary manganese concentrate contained 24.08% manganese (35.30% after burning) and the manganese recovery rate was 58.86 %, P / Mn 0.0069.
