    May 05, 2020 Froth flotation of Arufu ore was carried out at varying particle sizes after characterization. Fifty (50) kilogram crude sample of the ore was sourced from Arufu zinc mine in Arufu town of Nassarawa state, Nigeria. The whole sample was crushed out of which five (5) kilogram was sampled out using random sampling method. One kilogram each of the resulting

    Nov 01, 2021 Fuerstenau et al. said that no metallurgical process developed in the twentieth century was comparable to froth flotation, and it had a profound on the mineral industry. Indeed, it has been widely used in many fields, from the initial sulfide minerals to nonsulfide ores, as well as nonmetallic minerals and other materials [14] , [15] , [16

    Dec 31, 2021 Terpenic oil (TO) is commonly used as a flotation frother for the selective separation of sulfide minerals. As a frother, most reports have mainly focused on its effect on froth stability and froth entrainment, whereas its influence on the floatability of sulfide minerals has received little attention. In this work, the influence of TO on the flotation behavior of
