本文介绍了黄岗铁锡矿的化学成分、矿物组成及矿石结构构造。矿石中铁、锡、砷、钨和锌均主要呈单矿物状态存在,可综合回收。锡石粒度细小,且有部分锡呈胶态锡赋存于脉石等矿物中,选矿回收率会偏低。除磁铁矿本身含少量锡、砷外,另有部分极细小的锡、砷矿物包于其中,用机械选矿法不可能获得含锡、砷合格的铁精矿,必须对其再处理,以获得高质量铁精矿和再回收一部分锡、砷等。
This paper introduces the chemical composition, mineral composition and ore structure of Huanggang iron tin mine. Iron ore, tin, arsenic, tungsten and zinc are mainly single mineral state exists, can be comprehensively recovered. Cassiterite size is small, and some tin colloidal tin was found in gangue and other minerals, beneficiation recovery rate will be low. In addition to magnetite itself contains a small amount of tin, arsenic, in addition to some very small tin, arsenic minerals are included in the use of mechanical beneficiation method is not possible to obtain tin, arsenic qualified iron concentrate, it must be reprocessed to Get high quality iron ore concentrate and recycle some tin and arsenic.
