Experimental Study on Magnetization Roasting and Magnetic Separation of Iron Ore from Sidaogou Ⅷ Orebody
At present,the beneficiation process of Sidaogou Concentrator is dry separation-grinding wet magnetic separa-tion.Due to the high content of hematite,siderite,limonite and other weak magnetic minerals in the ore,the recovery rate of concentrate is only 34.87%,and the metal loss is relatively serious.In order to improve the recovery rate of concentrate and increase economic benefits,the magnetic roasting and magnetic separation test study was conducted on the raw ore of Sidaogou Ⅷ orebody.After the raw ore is roasted,the recovery rate of concentrate can reach 64.07%,which is 29.2 per-centage points higher than the recovery rate of direct grinding of raw ore.The industrialization of this process is expected to greatly improve the economic benefits of the concentrator.
