In this paper,a series of leaching tests on highly oxidized copper ore in Yunnan Province are conducted in the laboratory,such as leaching tests on different grinding meshes,leaching time,the ratio of liquid to solid,the consumption of sulphuric acid,etc.

The characteristic of the refractory oxidized copper ore is the high oxidation ratio,the high combination ratio,the target is bad by flotation.

The characteristic of the refractory oxidized copper ore is the high oxidation ratio,the high combination ratio,the low grade of raw ore,it can't reach ideal target by flotation.

The paper introduces the research of mineral processing test of some low-grade copper oxide ore in Yunnan.

By the technology of advanced copper hydrometallurgy which is heap leaching-solvent extraction-electrodeposition for treating low grade copper oxide ore or roasting-leaching-electro-deposition for treating copper sulphide ore,more eligible electrolytic copper is produced,at the same time,produce cost is decreased.

Copper oxide ore distributes the margin of Tarim basin in Xinjiang.

This experiment study the influence of the oxide copper ammonia leaching by microwave radiating,The result show:microwave radiating has obvious catalysis in the oxide copper ore ammonia leaching.

Experimental investigation on comprehensive utilization of the residue from oxide copper ores ammoniac leaching;

Flotation research of oxide copper ores was carried out in Tangdan and the research result was applied in industrial practice successfully.

According to the characteristics of the refractory copper oxide ores with the high oxidation ratio and combination ratio, and the low grade of raw ore, the gangue is alkaliferous gangue, and majority of the gangue is huntite, we investigation effects of collectors on the flotation sparation of the copper ore.

This paper gave technology and character of CuSO_4 production from waste copper, waste copper alloy, copper oxide ores, waste cupric liquor, etc.
