Full article:

This paper aims to evaluate the reuse of copper slag through hydrometallurgical and pyrometallurgical routes to recover metals contained in the waste of smelters or use it as a source of raw material in other products with higher added value. For this, waste characterization analysis were carried out using X-ray diffraction - EDS, atomic spectrometer and scanning electron microscopy – SEM. The results of flotation and leaching tests on a laboratory scale, tests using a pilot furnace with submerged lance, as well as tests in an industrial electric furnace were also evaluated. The results showed that there is technical feasibility for recovering copper, as well as a high potential for applications in the production of ceramics and porcelain tiles, beyond the uses already recognized by the market.
