Abstract

CARACTERIZADO PORQUE COMPRENDE LOS PASOS: A) PROVEER UN MATERIAL MINERAL AURIFERO PARTICULADO (TRITURADO EN UN AMBIENTE SUSTANCIALMENTE LIBRE DE GAS OXIGENO) QUE CONTIENE ORO ASOCIADO A UN MINERAL SULFURADO; B) SOMETER A DICHO MATERIAL MINERAL A FLOTACION, QUE COMPRENDE EL TRATAMIENTO DE UNA LECHADA LIQUIDA DE DICHO MATERIAL MINERAL CON UN GAS DE FLOTACION ENRIQUECIDO EN GAS NITROGENO (PREFERENTEMENTE MAYOR DE APROXIMADAMENTE 95% EN VOLUMEN DE GAS NITROGENO, O, SUSTANCIALMENTE LIBRE DE OXIGENO Y COMPONENTES QUE PODRIAN OXIDAR AL AZUFRE DEL SULFURO EN DICHO MINERAL SULFURADO), PARA SEPARAR DICHO MATERIAL MINERAL EN POR LO MENOS DOS FRACCIONES: 1) UN CONCENTRADO DE FLOTACION ENRIQUECIDO EN DICHO MATERIAL SULFURADO, QUE SE SOMETE A UN TRATAMIENTO OXIDATIVO PREFERENTEMENTE A PRESION, EN PRESENCIA DE UN GAS DE TRATAMIENTO ENRIQUECIDO EN GAS OXIGENO EN RELACION CON EL AIRE AMBIENTE, PARA FACILITAR LA POSIBLE RECUPERACION SUBSIGUIENTE DE DICHO ORO; Y 2) UNA COLA DE FLOTACION ENRIQUECIDA EN MINERAL NO SULFURADO
