![]() ![]() The technology of laterite ore smelted in BF was industrialization firstly in China, and developed the theory and practice further. in the course of smelting, high smelting temperature, serious dust pollution, etc. The advantage of pyrometallurgical technologies of laterite-nickel ore was mature, simple and effective, etc, while its disadvantage were high energy consumption, excessive slag. The technical characteristics of the main pyrometallurgical technologies of laterite-nickel ore were discussed. Main technical process to extract Ni from laterite-nickel ore were pyrometallurgical technologies currently. #Submerge arc furnace full#The full article was published in January 2018 in the Journal of Sustainable Metallurgy. Please visit for the conference proceedings paper. Depending on the upstream process, the slag is either liquid-charged via launders into the furnace or is cold-charged in solid form via conventional feeding systems. The main function of the furnace is the reduction of the matte and metal level in the slag. Slag cleaning furnaces are commonly connected to smelting units such as Teniente and Noranda converter, Outokumpu flash smelter, reverbertory furnaces. Especially slag cleaning furnaces have supplied more than 20 in the last 40 years. ![]() During this time numerous applications were constantly developed serving various user. SMS group has been developing this technology for 100 years, and has supplied a diverse market with about 700 furnaces and major furnace component. It becomes apparent that the application of the submerged arc furnace (SAF) in non-ferrous metallurgy processes is increasing, in particular for the extraction of zinc, lead, copper and nickel, but also for the processing of residues and stripping of slag. ![]() In metallurgical production, the traditional aim is to increase recovery of metal to the maximum. ![]()
