福建建瓯钟山铜铅锌矿,属于比较难选的中温热液脉状多金属复杂硫化矿。该矿床在1973、1975、1977年普查勘探的各个阶段,分别做了三次可选性试验。由于选别指标不好,地质勘探虽然结束多年,终因没有解决选矿问题而不能开采。1985年,省工业主管部门为了解决开发后备基地问题,委托长沙矿冶研究院对该矿重新进行选矿试验研究,获得了较好的选别指标。为深入认识这样一个在矿石性质上比较特殊的多金属硫化矿,对影响其分选效果的原因进行探讨。
Fujian Jianou Zhongshan Copper-Lead-Zinc Mine, which belongs to the more intractable medium-temperature hydrothermal vein-polymetallic sulphide ore. The deposit made three optional experiments at all stages of census exploration in 1973, 1975 and 1977. Due to the poor sorting index, although geological prospecting ended for many years, it could not be exploited because it did not solve the dressing problem. In 1985, the provincial department in charge of industry in order to solve the problem of developing reserve base, commissioned Changsha Institute of Mining and Metallurgy to re-beneficiation pilot study of the mine, get a better sorting index. In order to know more about such a kind of polymetallic sulphide ore, which is rather special in the nature of ore, the reasons that affect its sorting effect are discussed.
