| 摘 要： | 四川某金矿石属于高硫含碳微细粒难选金矿矿石，经常规浮选所得精矿金品位只有２５ｇ／ｔ左右。通过深度精选，采用载体转移浮选技术，获得了金品位７３．８５ｇ／ｔ金精矿，作业回收率达９１．５６％，并综合回收了银和硫，可显著地提高了选厂经济效益。

| Abstract: | A kind of gold ore from a gold mine in Sichuan Province belongs to high sulphur and finegrained gold ore containing carbon.The grade of gold concentrate obtained by way of conventional flotation is only 25g/t or so.Adopting depth cleaning and carrier flotation,the gold grade comes to 73.85g/t and operation recovery rate reaches 91.56% besides comprehensive recovery of silver and sulfur.As a result,the economic benefit raises markedly. |
