ESTA INVENCION ESTA RELACIONADA CON EL PROCESAMIENTO HIDROMETALURGICO DE MINERALES NIQUELIFEROS O COBALTIFEROS Y, EN PARTICULAR, CON LA OBTENCION DIRECTA DE NIQUEL Y COBALTO DE UNA LECHADA LIXIVIANTE DE LATERITA MEDIANTE LA EXTRACCION CON RESINA DE INTERCAMBIO DE IONES, LA CUAL ES LUEGO FISICAMENTE SEPARADA DE LA LECHADA LIXIVIANTE. LA RESINA ES SEPARADA DE LA LECHADA LIXIVIANTE AL CERNIRLA Y LUEGO SE SACA CON SOLUCION ACIDA. LUEGO DE SACARLA, LA RESINA VUELVE DE NUEVO AL CICLO DE CARGA. EL NIQUEL Y/O COBALTO PUEDEN SER EXTRAIDOS DEL ELUYENTE EN UNA FORMA SIGNIFICATIVAMENTE PURA MEDIANTE PROCESOS CONOCIDOS. LA LECHADA DESPROVISTA DEL METAL ES SOMETIDA AL TRATAMIENTO DE DESECHOS Y POSTERIORMENTE ES DESECHADA. ESTE PROCESO ELIMINA LA DIFICIL SEPARACION SOLIDO / LIQUIDO, LA CUAL DE LO CONTRARIO REQUERIRIA EXTRAER VALORES DE METALES DE LA LECHADA LIXIVIADA CARGADA.THIS INVENTION IS RELATED TO THE HYDROMETALURGICAL PROCESSING OF NIQUELIFEROS OR COBALTIFERAL MINERALS AND, IN PARTICULAR, WITH THE DIRECT OBTAINING OF NICKEL AND COBALT OF A LIXED LATERITE MILK BY EXTRACTION WITH THE EXCHANGE LABEL FACTOR LAW LIXIVING MILK. THE RESIN IS SEPARATED FROM THE LIXIVING MILK WHEN CERNIRED AND THEN REMOVED WITH ACID SOLUTION. AFTER REMOVING IT, THE RESIN RETURNS BACK TO THE LOAD CYCLE. THE NICKEL AND / OR COBALT MAY BE REMOVED FROM THE ELDER IN A SIGNIFICANTLY PURE WAY THROUGH KNOWN PROCESSES. THE DESPROVISTA METAL MILK IS SUBJECT TO WASTE TREATMENT AND IS DISPOSED AFTER. THIS PROCESS ELIMINATES THE DIFFICULT SOLID / LIQUID SEPARATION, WHICH OTHERWISE WOULD REQUIRE TO EXTRACT METAL VALUES FROM THE LOADED LIXED MILK.
