    A process to melt a copper sulphide mineral with high arsenic content. In the present document a method is provided for melting a copper sulphide concentrate with a high content of arsenic, which comprises the steps of: mixing the concentrate of copper sulphide with a high content of arsenic with quartz sand and a material containing CaO to obtain a mixed material; mix the mixed material with a reactive gas containing oxygen and heat for its reaction to obtain mat, slag and combustion gases containing SO2 . By the addition of CaO and SiO2in the melting process, the concentrate material, CaO and SiO2are allowed to react in the furnace at high temperature. The arsenic sulphides in the concentrate are first oxidized and then chemically react with the CaO in the slagging stream to enter the slag phase in the form of calcium-based compounds of arsenates of iron, arsenic, etc., reducing in this way the arsenic content in the copper matte.
