Abstract

<p>La presente invención está relacionada con el procesamiento de minerales lateríticos por la vía hidrometalurgica específicamente con la tecnología carbonato amoniacal ( Caron) y consiste en el tratamiento del carbonato básico de níquel, producto intermedio obtenido de la destilación del licor producto de la planta de lixiviación del mineral reducido el cual contiene óxido de cobalto como la mayor y más importante de las riquezas que limitan su calidad para distintos usos.</p> <p>Se han comprobado que con la calcinación a tempperaturas de 400-900 °C de este producto en presencia de compuestos no saturados de azufre y la lixiviación posterior de los calcinados con soluciones de ácido sulfúrico se obtienen soluciones concentradas de sulfato de níquel con relaciones de Ni/Co ≥ 2000 utilizables en la producción de sales de sulfato de níquel, polvos de níquel y níquel electrolítico prácticamente todo el cobalto en los residuos no disueltos.</p><p> The present invention is related to the processing of lateritic minerals by the hydrometallurgical route specifically with the ammonia carbonate technology (Caron) and consists of the treatment of basic nickel carbonate, an intermediate product obtained from the distillation of the liquor product of the plant leaching of the reduced mineral which contains cobalt oxide as the greatest and most important of the wealth that limits its quality for different uses. </p> <p> It has been proven that with calcination at temperatures of 400-900 ° C from this product in the presence of unsaturated sulfur compounds and subsequent leaching of the calcined with sulfuric acid solutions, concentrated nickel sulfate solutions with Ni / Co ratios ≥ 2000 are obtained that can be used in the production of nickel sulfate salts, Nickel powders and electrolytic nickel virtually all of the cobalt in the undissolved waste. </p>
