摘要
这是一篇矿业工程领域的论文。攀枝花是我国最大的钒钛磁铁矿资源基地,随着钒钛资源的开发利用,产出了巨量的尾矿,不仅占用大量土地,而且有用成分未能够被充分利用,造成资源浪费,同时还存在一定的安全、环境风险。本文选取了攀枝花地区22个具有代表性的尾矿库,开展尾矿资源潜力、有价元素赋存特征、可利用性、经济价值等系统研究。分析表明:攀枝花尾矿中含有大量的有价成分,潜在资源量巨大。其中铁金属量5200万t,平均品位10.87%,钛金属量为2907万t,平均品位6.08%,稀土金属量13.03万t,平均品位272 g/t,钴金属量4.23万t,平均品位88 g/t,钪金属量1.221万t,平均品位26 g/t,五氧化二磷总量249万t,平均品位0.52%。矿尾矿资源的综合利用主要有两个方向,一是二次开发利用,先进行铁、钛、硫、钴、磷等有价元素的回收利用;二是整体利用,在二次回收利用的基础上进行适当调配用于生产保温建筑材料、水泥、陶瓷、玻璃、耐火材料、土壤改良剂、混凝土和建筑用砂等。从而实现尾矿整体利用,最终解决尾矿资源化、减量化、无害化问题。
This is an essay in the field of mining engineering.Panzhihua is the largest vanadium-titanium magnetite resource base in China.With the development and utilization of vanadium titanium resources,a large number of tailings have been produced,which not only occupies a lot of lands but also useful ingredients are not fully utilized,resulting in resource waste.At the same time,there are certain safety and environmental risks.This paper selects 22 representative tailings ponds in the Panzhihua area to conduct systematic research on tailings resource potential,valuable element occurrence characteristics,availability,and economic value.Analysis shows that Panzhihua tailings contain a large number of valuable components and have a huge potential resource.The amount of iron metallicity is 52 million tons,with an average grade of 10.87%,titanium metallicity is 29.07 million tons,with an average grade of 6.08%,rare earth metallicity is 130300 tons,with an average grade of 272 g/t,cobalt metallicity is 42300 tons,with an average grade of88 g/t,scandium metallicity is 122100 tons,with an average grade of 26 g/t,and the Phosphorus pentoxide is2.49 million tons,with an average grade of 0.52%.There are two main directions for the multipurpose utilization of mineral tailings resources.One is secondary development and utilization,with advanced recovery and utilization of valuable elements such as iron,titanium,sulfur,cobalt,and phosphorus.The second is overall utilization,which is based on secondary recycling and appropriate allocation for the production of insulation building materials,cement,ceramics,glass,refractory materials,soil amendments,concrete,and construction sand.To achieve the overall utilization of tailings and ultimately solve the problems of tailings resource utilization,reduction,and harmless treatment.
