Abstract
Esta invencion proporciona un método mejorado para lixiviar minerales sin concentrar de metales preciosos y no preciosos, a partir de un mineral, que comprende el poner en contacto un mineral que posee metales o concentrado de mineral con una solucion de gas oxidante que comprende una solucion de un gas oxidante disuelto en un líquido perfluorado, dicho contacto se realiza antes de o durante la extraccion del metal precioso o no precioso del mineral. En otro aspecto más, esta invencion proporciona un método para destruir el cianuro de una solucion que contiene cianuro, que comprende el poner en contacto dicha solucion con una solucion de un gas oxidante disuelto, en un líquido perfluorado.
