Abstract: In order to scientifically determine the industrial development value of copper-bearing waste rock after photoelectric separation,aiming at the problem that the enrichment effect of copper-bear⁃ ing waste rock in different of grade range of raw material the mine is not clear and the economic feasibility is difficult to quantify,based on the grade and washability characteristics of different ores after separation, a whole process technical and economic model based on raw material grade interval is constructed,and a special study is carried out on the typical occurrence of phyllite-type and porphyry-type copper-bearing waste rock in a mining area.By means of metal comprehensive recovery value calculation and whole chain cost deconstruction analysis,the net income per ton of concentrate after separation is accurately calculat⁃ ed,and the quantitative results of photoelectric separation enrichment effect and economic benefit under different raw material grade intervals are obtained. It is clear that phyllite-type and porphyry-type copper�containing waste rocks can achieve effective enrichment and have positive economic benefits in their re⁃ spective suitable grade range. The photoelectric separation of copper-containing waste rock is feasible for industrial development in a specific grade range,which can provide scientific basis and technical support for the efficient utilization of copper-bearing waste rock.

Key words: copper-bearing waste rock, photoelectric separation, grade range of raw material, enrich? ment effect, technical and economic model, economic feasibility
