Abstract
Procedure for the extraction of metals from minerals containing sulfurs, through microbial leaching. Is to submit the mineral to tostation in a non-oxidizing gas mantle, after mixing it with carbon and with a sulfurated mineral, preferably pirite, to get a sulfide value of 10-70%. Below it is subjected to microbial leaching by percolation or in a suspension of fine mineral particles in an acid aqueous medium containing bacteria. It has applications to minerals that contain a high proportion of ganga and to concentration of unwanted components, such as iron, sulfur and arsenic.
