Abstract

"PROCESSO PARA RECUPERAR METAIS VALIOSOS A PARTIR DE MINéRIOS DE LATERITA E CONCENTRADOS QUE ESTãO CONTAMINADOS COM FERRO". Expõe-Se um processo para recuperar metais valiosos a partir de minérios de laterita e concentrados que estão contaminados com ferro. O processo inclui reduzir íons férricos a íons ferrosos em um licor de lixiviação que contém um metal valioso e ferro em solução utilizando um agente redutor, neutralizar o licor para reduzir a concentração de ácido livre em solução a níveis adequados para precipitação de níquel; e precipitar o metal valioso utilizando-se o agente redutor e partículas de semente sob condições de processo, incluindo uma ou mais dimensões de partícula de semente, composição de semente, e temperatura, que são selecionadas de forma a elevarem ao máximo a precipitação de níquel e reduzirem ao mínimo a precipitação de ferro."PROCESS FOR RECOVERING VALUABLE METALS FROM LATERITE AND CONCENTRATED ORES THAT ARE CONTAMINATED WITH IRON". A process for recovering valuable metals from laterite ores and concentrates that are contaminated with iron is exposed. The process includes reducing ferric ions to ferrous ions in a leach liquor containing a valuable metal and iron in solution using a reducing agent, neutralizing the liquor to reduce the free acid concentration in solution to levels suitable for nickel precipitation; and precipitating the valuable metal using the reducing agent and seed particles under process conditions, including one or more seed particle dimensions, seed composition, and temperature, which are selected to maximize nickel precipitation. and minimize iron precipitation.
