Embodiment 1
[0037] The coal gangue in the semi-industrial test is coal gangue from a mining area of Shanxi Juyi Industrial Group, with a fixed carbon content of 11.83% and an ash content of 80.63%, of which SiO2 is 64.71% and Al2O3 is 22.51%. The laterite nickel ore is ore from a certain place in Indonesia. The main components of the laterite nickel ore are: Ni 1.84%, Fe 15.52%, MgO 13.63%, SiO2 45.71%. In the test process of preparing inorganic mineral fibers from coal gangue, laterite nickel ore is used as a slag type regulator, and a certain amount of lime is added to smelt it in a submerged electric furnace, and the by-product nickel-iron alloy is produced while preparing fibers. Obtained better technical indicators.
[0038] The semi-industrial test uses a raw material ratio of coal gangue: laterite nickel ore: lime = 42:40:18, smelting and melting in a 1000KVA submerged thermal electric furnace for 4 hours; Insulation electric furnace, and then feed the centrifuge with a continuo...
