Abstract
A micaceous hematite sample from Krishnapuram village, Veldurthi Mandal, Kurnool district, Andhra Pradesh was received for process evolution studies to obtain coating - welding rod - concentrate, assaying Fe>65%, SiO2<2%, Al2O3<2% LOI<1% and 100%<0.1 mm or pellet grade concentrate assaying Fe>63%, SiO2<4%, Al2O3<3% LOI<2% and 100%<0.1 mm. The sample analyzed 52.44% Fe (T), 23.63% SiO2, 0.55% Al2O3 and 0.64% LOI. It contained mainly very fine grained specularite associated with subordinate amounts of fine grained quartz and minor to trace amounts of hematite, magnetite and gibbsite. The process amenability test indicated that the sample is amenable to gravity and magnetic separation. The final test comprises of WHIMS at -200 mesh, >10000 gauss intensity produced a concentrate assaying 65.29% Fe, 4.07% SiO2, 0.42% Al2O3 and 0.32% LOI with 76.8% Fe distribution at wt% yield of 62.1, meeting pellet grade specifications. The above rougher concentrate after one cleaner WHIMS at >8500 gauss, assayed 67.80% Fe, 1.90% SiO2, 0.32% Al2O3, 0.22% LOI and 5 specific gravity with 63.6% Fe distribution at wt% yield of 50.0 meeting the specification of coating and welding rod industry.
