Abstract

A method for dressing the complex copper oxide ore consisting of the copper oxide ore easy to dress and the copper oxide ore difficult to dress includes such steps as preparing multiple kinds of composite dressing chemical, floatation for the fine-particle copper oxide ore easy to dress, removing mud, forced floatation for the coarse-particle copper oxide ore difficult to dress, grinding the specially complex copper oxide ore, and forced floatation.

Description

technical field [0001] The invention relates to an ore dressing method, in particular to a method for sorting complex copper oxide ores. Background technique [0002] At present, for copper oxide ore containing malachite, chrysocolla, azurite, bileite, cuprite and other minerals, it is difficult to obtain better technical and economic indicators by conventional flotation methods. Especially the selection of copper oxide ore containing hydroxide iron ore slime has worse indicators. The way that prior art carries out flotation to copper oxide ore has: (1) conventional vulcanized xanthate flotation method, it is only suitable for selecting single and easy-selected malachite, to complex and difficult-to-select copper oxide ore, then flotation The selected indicators are extremely low; (2) hydrothermal vulcanized xanthate flotation method, which consumes a lot of energy; (4) Amine flotation method requires desliming in advance, and desliming will cause copper loss; (5) Chelatin...
