Abstract
QUE COMPRENDE: a) OXIDAR A PRESION UNA MEZCLA LIQUIDA QUE CONTIENE UN MINERAL BRUTO CON HIERRO, AZUFRE EN FORMA DE SULFURO Y PLATA, DONDE AL MENOS UN 70% DEL AZUFRE SE CONVIERTE A AZUFRE EN FORMA DE SULFATO; b) RECUPERAR DE (a), UNA MEZCLA LIQUIDA QUE CONTIENE SOLIDOS DE DESCARGA Y LIQUIDO DE DESCARGA ACUOSA, DONDE DICHOS SOLIDOS CONTIENEN AL MENOS UNA PORCION DE PLATA Y AL MENOS UNA PORCION DE HIERRO DEL MINERAL BRUTO; Y, c) LIXIVIAR POR LO MENOS UNA PORCION DE DICHOS SOLIDOS, CON UNA SOLUCION DE LIXIVIACION PARA DISOLVER EN DICHA SOLUCION POR LO MENOS UNA PORCION DE PLATA DE DICHOS SOLIDOS. LA SOLUCION DE LIXIVIACION ES UNA DE CIANURO, Y ES EFECTUADO A UN pH DE AL MENOS 9,5. SE AGREGA UN MATERIAL LIGANTE CON EL SULFATO EN (a), SIENDO DICHO MATERIAL COMPUESTOS DE CALCIO, SODIO, POTASIO, MAGNESIO Y COMBINACIONES DE LOS MISMOS. EL PASO (a) SE LLEVA A CABO A UNA TEMPERATURA DE AL MENOS 160°C
