湖南青山硫铁矿属 中小规模,主要有用矿 物为黄铁矿(占36％),脉 石矿物中白云石和方解石占61％,还有少量的石英(占1％)。主要有害元素Pb、Zn、As均低于硫铁矿制酸的质量标准,但矿石碱度较高,已超过制酸最高允许值(<0.8),需进行选矿。分别进行了中性矿浆和弱酸性矿浆的浮选试验,跳汰浮选试验,跳汰试验,所得工艺指标列于下表。

Hunan Qingshan pyrite is a small and medium-sized, the main useful minerals pyrite (36%), dolomite and calcite gangue minerals accounted for 61%, there are a small amount of quartz (1%). The main harmful elements Pb, Zn and As are lower than the quality standards of pyrite making acid, but the ore alkalinity is higher than the maximum allowable value of acid production (<0.8), and mineral processing is required. The flotation tests of neutral pulp and weak acid pulp were carried out respectively, and the flotation test and the jig test were performed. The process indexes obtained are listed in the following table.
