Abstract
Procedeul de recuperare a Ni si Co din minereuri si alte materiale oxidice, conform inventiei, prevede arderea reducatoare la 500 - 900 degree C a materialului oxidic preamestecat cu diversi aditivi -SO2, H2S, HCl si derivati metalici halogenati, urmata de lesierea amoniacala a cenusii rezultate prin tratare cu solutie de carbonat de amoniu în conditii cunoscute pentru solubilizarea Co si Ni care se separa în continuare uzual. în scopul optimizarii fluxului tehnologic, se efectueaza pretatarea meterialului proaspat fin divizat cu gaze de ardere avacuate din faza de reducere si care contin aditivul gazos de preferinta clorurat la temperatura cuprinsa între 50 si 600 degree C un timp suficient pentru retinerea aditivului în sarja în proportie de 2....4% si epurarea gazelor mentionate.The process for the recovery of Ni and Co from ores and other oxide materials according to the invention provides for the reduction of the oxidation material pre-mixed with various additives - SO2, H2S, HCl and halogenated metallic derivatives to 500-900 ° C followed by the ammoniacal ash resulting from treatment with ammonium carbonate solution under conditions known for the solubilization of Co and Ni which are usually further separated. In order to optimize the technological flow, the finely divided fresh particulate material is fed with combustion gases fed from the reduction stage and containing the chlorinated pre-chlorinated additive at a temperature between 50 and 600 ° C for a time sufficient to retain the additive in the batch in a proportion of 2 .... 4% and the purification of said gases.
