Abstract

"MéTODO PARA PROCESSAMENTO DE NìQUEL OXIDADO E MINéRIO DE COBALTO". O grupo de invenções refere-se à métodos de extração de níquel e cobalto a partir de níquel oxidado e minério de cobalto Þ capacitar o aumento da extensão da extração do níquel. O caminho de processamento do níquel oxidado e minério de cobalto passa por uma primeira variante que inclui um tratamento de minério por ácido sulfúrico com a transferência de sulfatos solúveis à solução, na qual a conexão com o minério granulado com ácido sulfúrico, sendo os granulados sulfatados à uma temperatura de 250-450<198>C durante 1-2 horas em uma ou duas etapas, após as quais a lixívia da água dos sulfatos de níquel e outros metais são feitos, e então os metais são extraídos a partir de solução de métodos conhecidos. Ao mesmo tempo a primeira etapa é conduzida à uma temperatura de 250-300<198>C, a segunda etapa à uma temperatura de 350-450<198>C, e a sulfatização dos granulados é realizada à um consumo estequiométrico de ácido sulfúrico. O método de processamento do níquel oxidado e minério de cobalto através da segunda variante também inclui um tratamento de minério por ácido sulfúrico com a transferência de sulfatos solúveis para a solução, sendo o minério granulado com ácido sulfúrico em uma quantidade estequiométrica requerida, sendo os granulados calcinados à uma temperatura de 650-700<198>C durante 2,5-3,0 horas após a agia lixívia ser conduzida. Além disso, a calcinação dos granulados é continuada até o conteúdo do ferro solúvel alcançar os limites de 1,0-3,9 e antes da calcinação os granulados serem sulfatados à uma temperatura de 200-250<198>C durante 1 hora. O método de processamento do níquel e minério de cobalto através da terceira variante incluem tratamento do minério por ácido sulfúrico com a transferência de sulfatos solúveis para a solução, enquanto, especificamente, o minério é granulado com ácido sulfúrico, os granulados são calcinados nos gases da atmosfera recebidos durante a oxidação de elementares súlfur ou sulfides por oxigênio do ar, com os gases juntos com óxido de súlfur emitindo durante a calcinação de granulados sendo liberados para a produção de ácido sulfúrico e os granulados sendo processados por lixívia por água."METHOD FOR RUSTY NICKEL AND COBALT ORE PROCESSING". The group of inventions refers to the methods of extracting nickel and cobalt from oxidized nickel and cobalt ore enabling the increased extent of nickel extraction. The processing path of oxidized nickel and cobalt ore goes through a first variant that includes a sulfuric acid ore treatment with the transfer of soluble sulfates to the solution, in which the connection to the sulfuric acid granulated ore, the sulfated granules being at a temperature of 250-450 ° C for 1-2 hours in one or two steps, after which water bleach from nickel sulfates and other metals is made, and then the metals are extracted from solution of known methods. At the same time the first stage is conducted at a temperature of 250-300 ° C, the second stage at a temperature of 350-450 ° C, and the sulphation of the granulates is performed at a stoichiometric consumption of sulfuric acid. The method of processing the oxidized nickel and cobalt ore through the second variant also includes sulfuric acid ore treatment with the transfer of soluble sulfates to the solution, the ore being granulated with sulfuric acid in a required stoichiometric amount, the granules being calcined at a temperature of 650-700 ° C for 2.5-3.0 hours after the bleaching agent was conducted. In addition, the calcination of the pellets is continued until the soluble iron content reaches the limits of 1.0-3.9 and before calcination the pellets are sulfated at a temperature of 200-250 ° C for 1 hour. The method of processing nickel and cobalt ore through the third variant includes treatment of the ore by sulfuric acid with the transfer of soluble sulfates to the solution, while specifically the ore is granulated with sulfuric acid, the granulates are calcined in the gases of the atmosphere received during the oxidation of elemental sulfur or sulfides by oxygen from the air, with the gases together with sulfur oxide emitting during the calcination of pellets being released for sulfuric acid production and the pellets being bleached by water.
