Abstract

De acuerdo a la presente invención, se proporciona un proceso de lixiviación atmosférico para la recuperación del níquel y del cobalto a partir de un mineral laterítico, dicho mineral laterítico incluye una porción baja en mineral de magnesio y una porción alta de mineral de magnesio, dicho proceso incluye las etapas de:(a) formar una pulpa acuosa de dicho mineral laterítico,(b) lixiviar dicha pulpa acuosa con un ácido de mineral concentrado a presión atmosférica para producir una pasta aguada que contiene un licor madre de lixiviación y un residuo de lixiviación,(c) tratar el licor madre de lixiviación ya sea separadamente o como parte de dicha pasta aguada para recuperar a partir de éste el níquel y el cobalto disueltos, dejando una solución estéril que contiene magnesio.(d) Tratar dicha solución que contiene magnesio para recuperar a partir de ésta la sal que contiene magnesio.Una ventaja de la invención es la provisión de un método eficiente y económico para lixiviar tanto los minerales con bajo magnesio (por ejemplo limonita) y minerales con alto magnesio (por ejemplo saprolita) en una etapa de proceso simple a presión atmosférica, para obtener una disolución con un alto porcentaje de níquel y cobalto. Otra ventaja del método es que evita los altos costos de capital que se asocian con las sofisticadas autoclaves.Otra ventaja de una forma preferida del método es que evita además la producción de jarosita. Una ventaja de una forma preferida de la invención, es que la solución madre que contiene magnesio que se produce a partir del proceso de lixiviación se trata para recuperar el sulfato de magnesio, el que luego se procesa para proporcionar MgO, Mg(OH)2 o MgCO3 y SO2. El SO2 se usa en forma ventajosa para regenerar el H2SO4. El MgO o MgCO3 se pueden retroalimentar en el proceso de lixiviación como un agente neutralizante, que dispone de un residuo estable, o que se vende como un producto comercial.According to the present invention, an atmospheric leaching process is provided for the recovery of nickel and cobalt from a lateritic mineral, said lateritic mineral includes a low portion in magnesium ore and a high portion of magnesium ore, said The process includes the steps of: (a) forming an aqueous pulp of said lateritic mineral, (b) leaching said aqueous pulp with a mineral acid concentrated at atmospheric pressure to produce a watery paste containing a leach liquor and a residue of leaching, (c) treating the leaching mother liquor either separately or as part of said glued paste to recover dissolved nickel and cobalt from it, leaving a sterile solution containing magnesium. (d) Treating said solution containing magnesium to recover from it the salt containing magnesium. An advantage of the invention is the provision of an efficient and economical method for ra leach both minerals with low magnesium (for example limonite) and minerals with high magnesium (for example saprolite) in a simple process stage at atmospheric pressure, to obtain a solution with a high percentage of nickel and cobalt. Another advantage of the method is that it avoids the high capital costs that are associated with the sophisticated autoclaves. Another advantage of a preferred method is that it also avoids the production of jarosite. An advantage of a preferred form of the invention is that the stock solution containing magnesium that is produced from the leaching process is treated to recover magnesium sulfate, which is then processed to provide MgO, Mg (OH) 2 or MgCO3 and SO2. SO2 is advantageously used to regenerate H2SO4. MgO or MgCO3 can be fed back into the leaching process as a neutralizing agent, which has a stable residue, or is sold as a commercial product.
