    Abstract:

    This paper intends to find some alternatives to recover gold associated with oxide and sulphide ore by mixing its main component (copper sulfide) with oxide ores using for this purpose the metallurgical flotation process. The development of this research has evaluated samples of this type of ore content of 15%, 10% and 5% of oxidized ore. This way is to evaluate which of these allow us to obtain a higher gold recovery without damaging the copper grade and recovery thereof in the concentrate. To determine the mineralogical species, with which is associated the gold, and the degree of release of such species has made a study of optical microscopy of polished sections: Head, concentrate and tailings. At the end of the study better metallurgical performance 15g / t of a mixture of (formatexanthate + thionocarbamate) is obtained, achieving a 13% increase in the recovery of gold.
