| 中文摘要: |
| 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。 |
| 英文摘要: |
| 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. |
