一、铜云南省的铜资源约为全国的16%,但品位大于1%的只占40%左右,难选矿居多,全省有大小铜选厂17个,日处理矿石量为×万吨左右,均采用常规的单一浮选流程.按脉石矿物的组成,可将云南省的铜矿分为钙镁型铜矿、硅铝型铜矿和含铜黄铁矿型铜矿三大类型.现分别加以评述
First, the copper resources in Yunnan province are about 16% of the national total, but only about 40% are those whose grade is greater than 1%. Most of the refractory deposits are mined. There are 17 copper processing plants in the province, with an annual processing capacity of about 10,000 tons of ore , All adopt the conventional single flotation process.According to the composition of gangue minerals, the copper deposits in Yunnan Province can be divided into three types: Ca-Mg type copper, Si-Al type copper and copper-bearing pyrite types. Now be reviewed separately
