广西某堆积氧化锰矿是我国重要的锰矿原料产地之一。由于矿石含锰低,含铁高,不能直接用于冶炼锰铁合金,加之矿石中锰矿物和铁矿物嵌布较细,致密共生,很难用简易方法使之有效地分离。从矿石性质上来看,该地区除少数矿山外,大部分锰矿都属此类型,故该堆积氧化锰矿具有一定的代表性。为寻求合理的选矿方法,获得优质的锰精矿,从1960年以来,进行了各种选矿方法的试验研究。在此基础上,
Guangxi, a pile of manganese oxide ore is one of the important origin of manganese ore. As the ore contains low manganese and high iron content, it can not be directly used for smelting ferromanganese alloy. In addition, the manganese minerals and iron minerals in the ore are densely embedded and densely symbiotic, which makes it difficult to separate them effectively by a simple method. From the point of view of ore quality, except for a few mines in this area, most of the manganese ore belonged to this type, so the accumulated manganese oxide ore was representative. In order to find a reasonable beneficiation method and to obtain high-quality manganese concentrate, a pilot study on various beneficiation methods has been carried out since 1960. on the basis of,
