复合矿石是指几种主要有用组份(或矿物)同时达到工业指标要求，可供综合回收利用的矿石。如铜铅锌矿石、铁锰矿石、铜钼矿石、钨锡矿石、铜钴镍矿石、汞锑矿石，等等。
该工艺将矿石通过煅烧、分离、碳化、焙烧等过程，加工成镁、碳酸钙和复合肥。
This technology changes the ore into magnesium, calcium carbonate and compound fertilizer through calcination, separation, carbonization and roasting.
矿石类型以含金方解石-石英复合脉为主，其次为含金构造角砾岩型和含金蚀变岩型。
The major ore type is gold-bearing calcite-quartz vein, secondly is gold-bearing tectonic breccia, and gold-bearing altered rock.
研制合成了甲基异戊基黄药及其复合黄药，与丁基黄药、异丁基黄药进行的选矿对比试验表明，复合黄药具有较强的捕收能力和较好的选择性，是一种性能优良的复杂难选铜矿石的捕收剂。
When mixed xanthate CES formed by the combination of variotls xanthates is applied in the flotation of the oxide ore, it has the advantages of high collection Power and fast flotation speed.
