Title: BENEFICIATION-METALLURGY COMBINATION RECYCLING METHOD FOR SOLID INCLUSION COPPER OXIDE ORE
Abstract:
A beneficiation-metallurgy combination recycling method for a solid inclusion copper oxide ore. According to the purpose, high-intensity magnetic separation is performed on a copper oxide ore wrapped by a weakly magnetic ore which is difficult to recycle by floatation and has a direct acid leaching rate to obtain a magnetic product wrapped by copper oxide, the magnetic product is filtered, microwave drying and heating are performed, heating selectivity of microwaves on different ores in a solid inclusion is used, the temperature rises of the ores are different, volume expansions are different, so that cracks are generated, a diffusion channel is provided for subsequent sulfuric acid leaching, the leaching rate speed and the leaching rate are increased, and copper ore resources difficult to handle are efficiently recycled.
