摘要: Abstract An understanding of the breakdown mine costs is an important tool for researchers and developers who seek to place novel cost-reducing unit operations in wider general cost context. This paper provides a operating 63 mines by dividing them into three main categories: mining, milling, administrative (G & A) costs. The study looks at patterns mining type, mill processing mineral differences between expressed feasibility studies vs. mines. explores reasons relationships observed then presents total average breakdown. It was found that mean relative milling did not differ significantly, on they had equal shares enterprise Effects type were observed, with underground being significantly less than open pit gold occupying larger share copper-containing overall be ratios (43:43:14) (45:45:10) (Mine:Mill:G A). A treatment potential innovative technologies provided conclusion paper, including coarse particle recovery flotation grinding technologies.
