摘　　要：金属尾矿具有污染环境和资源再利用的双重特点。从综合利用的角度,对冀东金厂峪金矿尾矿化学成分、矿物组成,以及矿物粒度、解离度等进行了测试分析,以寻求适合该尾矿综合利用的途径。分析结果表明:金厂峪金矿尾矿属低铁高铝高硅尾矿;矿物组成以石英和长石为主,含少量的白云石、云母、方铅矿等矿物;尾矿粒度以细砂为主;尾矿中石英含量大于30%,与其他矿物连生关系简单。综合利用建议:①制备高纯度二氧化硅;②制备生产烧结砖等建筑材料;③制备微晶玻璃、釉面材料等高附加值产品;④制备环保材料、土壤改良剂、矿物肥料等产品;⑤作为井下充填材料。Metal tailings have the dual characteristics of environmental pollution and resource reuse.From the view of comprehensive utilization,we analyzed chemical compositions,mineral compositions,and mineral particle sizes,and dissociation degrees of the tailings in the Jinchangyu gold ore deposit,Eastern Hebei in order to find a suitable way for the comprehensive utilization of the tailings.The results show:The tailings of the Jinchangyu gold ore deposit are low iron,high aluminum,and high silicon tailings;The mian mineral compositions are quartz and feldspar,with a small amount of dolomite,mica,and galena,etc;Fine sands predominate in the particle sizes of tailings;The content of quartz in the tailings is more than 30%,which has a simple symbiotic relationship with other minerals.Suggestions for the comprehensive utilization:①Preparation of high purity silica;②Preparation and production of building materials such as sintered bricks;③Preparatione of high value-added products,such as glass-ceramics and glaze materials;④Preparations of environmental protection materials,soil improvers,and mineral fertilizers,etc;⑤Underground filling materials.
