海水浮选在我国是一个新课题,探索并研究海水对选矿工艺的影响,对开发利用我国沿海矿物资源具有重大现实意义。海水的组分与淡水大不相同,归纳其对选矿的影响有三,一是具有一定的起泡性;二是对矿浆pH值有一定的缓冲作用;三是对设备有强烈的腐蚀性。试验说明海水对某金矿各种不同矿石、不同流程均可得到与淡水相近的指标。采用煤油作捕收剂
Seawater flotation is a new topic in our country. To explore and study the influence of seawater on beneficiation process has great practical significance for the development and utilization of coastal mineral resources in China. The composition of seawater is very different from that of fresh water, and its influence on beneficiation is summarized as follows: first, it has certain foaming; second, it has some buffering effect on pH value of pulp; third, it has strong corrosiveness to equipment. Test shows that a variety of gold ore on the sea, different processes can be obtained with similar indicators of fresh water. Using kerosene as collector
