Abstract
La invención se refiere a la Rama de la hidrometalúrgia de los metales no ferrosos, en particular al tratamiento del mineral laterítico ferruginoso de Ni y Co con la utilización de los procesos de autoclave de la lixiviación de los procesos de autoclave de la lixiviación ácida de Ni y Co, separación de la solución y la cola, precipitación de sulfuro de Ni y Co de la solución. El método consiste en el lavado de las colas con la solución que contiene el reductor - hierro bivalente a Ph de 1,5 - 3,0 y la temperatura menor de 100 grado C, lo que permite hacer pasar por segunda vez a la solución Ni y Co, cooprecipitados con alunita que forma en el proceso de la lixiviación del mineral. Utilizando para el lavado de las colas las soluciones residuales después de la precipitación de sulfuros, - Fe2+, H2+ y el ácido sulfúrico, y también los sulfatos de una serie de metales aluminio, magnesio, cromo etc, se aumenta la concentración total de sulfato en la solución niquelífera, lo que aumenta la extracción en forma de sulfuros de Ni y Co en el curso de su realización. Además, el método permite eliminar la contaminación del medio ambiental, suspendiendo el consumo del agua potable para el lavado de las colas. La invención puede utilizarse en la industria cobalto-niquelíferaThe invention relates to the branch of hydrometallurgy of non-ferrous metals, in particular to the treatment of Ni and Co ferruginous lateritic ore with the use of autoclave processes of leaching of autoclave processes of Ni acid leaching. and Co, separation of the solution and the tail, precipitation of Ni and Co sulfide from the solution. The method consists of washing the tails with the solution containing the reducer - bivalent iron at Ph of 1.5 - 3.0 and the temperature less than 100 degree C, which allows to pass the Ni solution a second time and Co, co-precipitated with alunite that forms in the mineral leaching process. By using the residual solutions after precipitation of sulfides, - Fe2 +, H2 + and sulfuric acid, and also the sulfates of a series of metals, aluminum, magnesium, chromium, etc., for washing the tails, the total concentration of sulfate in the nickel-containing solution, which increases the extraction in the form of Ni and Co sulfides in the course of its realization. In addition, the method allows the contamination of the environment to be eliminated, suspending the consumption of drinking water for washing the tails. The invention can be used in the cobalt-nickel industry
