Abstract
Proceso para la remoción de arsénico desde materiales con un alto contenido de arsénico o materiales con un alto contenido de arsénico y selenio que comprende: - agregar el material a un reactor a presión, - agregar al reactor una solución lixiviante alcalina de una base fuerte disuelta en agua, - agregar al reactor un gas oxidante, - mezclar los componentes anteriores en el reactor para obtener una pulpa homogénea y someterla a una lixiviación a presión, la cual es selectiva para el arsénico con respecto a los demás elementos de interés presentes en el material tratado, - someter la pulpa obtenida de la etapa de lixiviación a una primera etapa de separación sólido - líquido, obteniendo un licor con arsénico disuelto y un sólido con bajo contenido de arsénico, - someter el licor con arsénico disuelto a una precipitación del arsénico con un agente precipitante, seleccionado de compuestos que aportan los siguientes cationes: Ce+3, Fe+3, Mg+2, y una combinación de Fe+3 y Ca+2, - someter el producto de la etapa de precipitación del arsénico a una segunda etapa de separación sólido - líquido, obteniendo un producto sólido de arsénico y un licor alcalino libre de arsénico; opcionalmente el proceso además comprende: - someter el licor alcalino libre de arsénico a una etapa de cristalización del sulfato de sodio (Na2SO4) disuelto, obteniendo una pulpa compuesta por cristales de Na2SO4 y un licor alcalino libre de Na2SO4, - someter el producto de la etapa de cristalización del Na2SO4 a una tercera etapa de separación sólido - líquido, obteniendo un sólido formado por cristales de Na2SO4 y un licor alcalino.
