1引言金属矿产的开发利用过程中产生的大量固体废弃物,大部分被露天堆放,其中含有大量的重金属元素,在雨淋和风化作用下进入土壤中,进而进入植物体内,对周围的生态环境及人体健康产生影响。尾矿是经过多次研磨,并用选矿剂选过之后的废弃物,其中重金属含量有升高趋势,并且尾矿粒度特别细小,易产生吸附等作用,堆放于地表,更容易产生表生环境问题,因此,尾矿产生的各种环境问题应受到关注。本文以攀枝花钒钛磁铁矿中尾矿为例,来研究尾矿中重金属对环境的影响。
1 INTRODUCTION The large amount of solid waste generated during the development and utilization of metallic minerals is mostly stored in the open air and contains a large amount of heavy metal elements which enter into the soil under the influence of rain and weather and enter into the plants and affect the surrounding ecological environment And human health impact. Tailings after repeated grinding, and with the dressing agent after the election of the waste, of which the content of heavy metals have an upward trend, and tailings particle size is particularly small, easy to produce adsorption and other effects, stacked on the surface, more prone to epigenetic problems Therefore, various environmental problems arising from the tailings should be concerned. In this paper, Panzhihua vanadium-titanium magnetite tailings, for example, to study the tailings of heavy metals on the environment.
