Abstract

Se describe un proceso para la lixiviación de un metal valioso de una mena que contiene el metal valioso, el proceso incluye los pasos de lixiviación de la mena en presencia de ácido clorhídrico para formar una sal soluble de cloruro de metal en una solución de lixiviación agregar dióxido de azufre a la solución de lixiviación; recuperar una sal del sulfato de metal o sulfito de metal de la solución de lixiviación; y regenerar el ácido clorhídrico. La mena puede ser una mena de metal de base oxídico, tal como una mena de óxido de zinc; una mena de níquel lateritico; tal como una mena saprolítica o limonítica; una mena de sulfuro o una mena de titanio. El metal valioso es seleccionado típicamente del grupo que consiste en Zn, Cu, Ti, Al, Cr, Ni, Co, Mn, Fe Pb, Na, K, Ca, metales del grupo del platino y oro. El metal en la sal de sulfato o sulfito de metal puede ser el metal valioso o puede ser un metal de menos valor que el metal valioso, tal como magnesio. El ácido clorhídrico regenerado se recicla dentro del proceso de lixiviación.A process for leaching a valuable metal from an ore containing the valuable metal is described, the process includes the leaching steps of the ore in the presence of hydrochloric acid to form a soluble metal chloride salt in a leaching solution add sulfur dioxide to the leaching solution; recovering a salt of the metal sulfate or metal sulphite from the leaching solution; and regenerate hydrochloric acid. The ore can be an oxidic base metal ore, such as a zinc oxide ore; a lateritic nickel ore; such as a saprolitic or limonitic ore; a sulfide ore or a titanium ore. The valuable metal is typically selected from the group consisting of Zn, Cu, Ti, Al, Cr, Ni, Co, Mn, Fe Pb, Na, K, Ca, platinum group metals and gold. The metal in the metal sulfate or sulphite salt may be the valuable metal or it may be a less valuable metal than the valuable metal, such as magnesium. The regenerated hydrochloric acid is recycled within the leaching process.
