黔西北含自然铜矿石样品加工方法研究

Processing Method Study of Native Cooper-bearing Rock Sample in Northwest Guizhou

通过对黔西北某地含自然铜矿石样品加工过程中的分级、缩分及均匀性试验,确定样品经粗碎、中碎后,过1 mm筛(筛上物检测Cu,参与以后计算),筛下物混匀缩分(K=0.5),采用棒磨细碎,过160目筛(筛上物检测Cu,参与以后计算),筛下物混匀的加工流程是可行的,其经济性、可靠性、准确性能满足该矿区地质工作的实际需要。

By grading,splitting and uniformity experiment during the natural cooper samples processing in northwest Guizhou,the coarse crushing and intermediate crushing of samples are determined,by 1 mm sleve,the undersize are mixed and splitted（ K = 0. 5）,grinding finely and screen 160 mesh,the processing of undersize mixing is available,the economy,reliability and accuracy can satisfy the realistic demand of geologic work in this mining area.
