国内外“人工矿床”研究现状与前景

“人工矿床”主要是指废石及尾矿等能被重新利用的资源，在富矿资源日益减少的今天，贫矿资源，废石及尾矿等非传统资源的开发利用越来越受到重视，目前，国内外主要从物质再回收和物质转移两个方面对废石和尾矿的综合利用进行研究。国外已利用细菌浸出等先进的矿物加工工艺从低品位的含铜和含金的废石和尾矿中回民铜和金，利用已无回收价值的尾矿加工制造水泥，陶瓷，玻璃等新型材料，国内主要利用重选，磁选，浮选，化学选矿联合工艺流程回民铁，铜，金等尾矿中的有用元素,利用废石，尾矿作建筑石料或加工制造砖，混凝土，陶瓷等建筑材料。

THE STATUS AND PROSPECT OF RESEARCH ON MANUAL MINERAL DEPOSITS IN THE WORLD

The manual mineral deposits are the gangues and tailings which can be re used. In pace with high grade ores reduced, development of low grade ores, gangues and tailings becomes more and more important. At present, the multipurpose use of gangues and tailings retrieved useful elements and material transferred at home and abroad. Biogeotechnology of metal and other advanced mineral processing technology crafts used to retrieve copper and gold from low grade tailings which contain copper and gold. Cement, ceramics , glass and other new materials were made from the tailings which aren't retrieved. The useful elements of iron, copper, gold were retrieved from tailings by gravity concentration, magnetic separation, froth flotation and chemistry of metal, bricks, concrete, ceramics and other building materials were made from tailings at home.
