Abstract: The Democratic Republic of Congo, one of the countries full of huge depositss of copper and cobalt ores, is also one of the countries with significant impact unrecycled mining releases whose negative impact on the environment is being felt on the environment and the people living along the shoreline. This article discusses the characterization of mining waste from the cobalt circuit of copper and cobalt ores (HGW), one of the wastes that presents one of the most complex management problems in the region. This characterization should serve as a guide in the choice of the method of its valuation. To characterize this waste, the following techniques were used: XRF, XRD, FTIR, SEM and DTA-TGA. The results showed that HGW has an extremely high pollution index (IP) and near 85 % wt. of CaSO4.2H2O. The presence of this phase in this waste makes it possible to consider its valuation in cement plant as a setting regulator.
