Abstract

PROCEDIMIENTO PARA MEJORAR EL RENDIMIENTO DE EXTRACCION DE PLATA Y ORO EN LOS MINERALES DE GOSSAN.CONSISTE EN PONER EN CONTACTO CON UNA SOLUCION ALCALINA DE SULFURO SODICO A LA EMPERATURA AMBIENTE EL GOSSAN DE CABEZA O BIEN EL GOSSAN DE COLA YA TRATADO AL QUE SE LE QUIERA EXTRAER LA PLATA RESIDUAL QUE TODAVIA CONTIENE. LA PUESTA EN CONTACTO CON ESTA SOLUCION ALCALINA DE SULFURO CON EL MINERAL EN CUALQUIER GRADO DE DIVISION PUEDE PRACTICARSE DE DIVERSAS MANERAS, COMO EN UN REACTOR TANQUE AGITADO O NO, EN UN REACTOR TIPO PACHUCA CON PASO DE UN GAS INERTE (NO OXIDANTE) O NO Y CON OBJETO DE AGITAR LA PULPA, EN CUALQUIER REACTOR O PRACTICANDO LA LIXIVIACION EN UNA COLUMNA EN LA QUE EL LECHO ES EL MINERAL, EN ESPESADORES O PREFERENTEMENTE MEDIANTE LIXIVIACIONES IN SITU, O EN UNA PISCINA, TERRAZA O EN EL MISMO SUELO, QUE ES COMO SE OBTIENEN LOS MEJORES RESULTADOS.
