Abstract: The copper oxide ore in Luanshya， Zambia， is an unexplored mining area with large reserves of ore resources， which belongs to low-grade and refractory deposit. In order to develop and utilize the refractory resources， the technological mineralogy investigation was carried out by chemical analysis， XRD， microscopy， SEM-EDS and other testing methods. The results showed that in the ore， the ratio of the particles more than 212μm， from 125 to 212μm， from 74 to 125μm， less than 74μm is 30.13%， 13.80%， 17.00%， 39.07%， respectively. There are four occurrence state types of copper in the ore: copper in mineral state， isomorphic copper， adsorbed copper， and a few copper in colloid co-precipitation. Among them， the copper in mineral state mainly exists in the form of malachite， chrysocolla and pseudo-malachiter. The isomorphic copper is mainly in the form of biotite， chlorite and muscovite. Adsorbed copper mainly exists in limonite. Colloid co-precipitated copper mainly exists in the cemented body of feldspar-quartz-copper-iron.
