Beneficiation of Iron in Thermal-Reduced Ilmenite by Magnetic Separation
Kariuki, Warui S.; Wachira, Jackson M.; Mutembei, Peterson K.; Waithaka, Peter N. (2013)ncreasing demands for Iron in countries development, and lack of conventional reducing agents has resulted into sourcing of alternative ways of beneficiating the iron ore. This paper reports on the study that was done ... -
Copper extraction by wet chemical method
Mutembei, Peterson K.; Wachira, Jackson M.; Mwangi, Isaac; Njoroge, Peter (Elsevier, 2018-07)In many countries large deposits of copper with no locally established copper based industries occur because known methods for extraction are prohibitively expensive and unaffordable. This study reports on an affordable and ... -
Effects of Temperature on Ilmenite During Concentration of Iron in Laterites Using Charcoal and Separation using Magnetic Separation
Mutembei, Peterson K.; Muriithi, Naftali T.; Njoroge, Peter W.; Muthengia, Jackson W. (IJSET, 2014-06)Effect of temperature on ilmenite minerals found in laterites has been investigated. It was found that during reduction of iron minerals in laterites to magnetite using charcoal at temperatures of about 500-700oC, ... -
Magnetic Concentration of Iron in Lateritic Soils from Kamahuha, Murang’a County, in Kenya using Carbon Monoxide Generated In-Situ
Njoroge, P. W.; Mutembei, Peterson K.; Wachira, Jackson M.; Wanjau, R. (IJSET, 2014-08)Chemical and Mineral Analyses of laterites from selected sites in Kamahuha area of Murang’a County, in the Republic of Kenya, have been carried out with particular interest in the levels of iron and the type of minerals ...
