A novel process for separating iron and titanium from Indonesian beach titanomagnetite (TTM) concentrates is proposed. This involves several steps, including mixing the TTM concentrate additive, pressing mixture into pellets, embedding direct reduction of magnetic separation. Given that coal additives are main factors influencing coal-based TTM, this study employed reduction, where pellets embedded under to be reduced, Na2SO4 was used as an additive. The best result obtained when dosage 4%,...
Abstract Magnetite tailings and municipal sludge is two different solid wastes. Large stockpiles of magnetite create serious environmental problems. In this study, a new method for preparing ceramsite from proposed. The effects factors including preheating temperature, time, roasting dosage on the physical properties were investigated. optimal conditions preparation determined as follows: tailings:municipal quality ratio 85:15, temperature 325°C, time 40 min, 1120°C, 6 min. Under these...
In this study, magnesium titanate was prepared through the high-temperature reaction of ilmenite and MgO in a reducing atmosphere, its formation process mechanism under different conditions were investigated. The results showed that atmosphere is necessary to prepare titanate. Although Mg could replace Fe form without reductant, generated contained large amounts iron. While promoted accelerated rate, because iron oxide system reduced metal atmosphere. effect reduction improved, content...
Abstract Lime mud (LM) is a kind of industrial solid waste produced in alkali recovery papermaking industry. LM global environmental challenge that both China and the United States are facing. With support EcoPartnership Program under 10‐year Sino‐US Energy Environment Cooperation Framework, Sun Paper Joint Stock Co., Ltd. has successfully formed partnership with America Mineral Technologies Inc. (MTI). MTI applied production technology calcium carbonate from by alkaline (PTCC) to Company....
Abstract In this study, taking a certain iron ore tailings pond as the research object, closed engineering design was conducted to ensure its sustained and stable operation. Firstly, installation of flood drainage system (spillway) closure existing overflow tower pipe are suggested. Secondly, numerical analysis is on seepage field dam body determine position saturation line under normal water storage level level. Subsequently, stability various working conditions assessed using limit...
Abstract Effects of CaF 2 on the mineralogical composition and microstructure reduction products at different temperatures during direct beach titanomagnetite is investigated. In absence , armalcolite a large number small‐size metallic iron particles in prevented separation Ti Fe. The metallization rate was only 90.32 wt% 1350°C. reduced activation energy reaction promoted armalcolite, further achieving Fe mineral phase. When 5 added 1250°C, could reach 90.88%. effect better than that...
Coal-based direct reduction followed by magnetic separation was used to produce iron powder (DRIP) from a titanomagnetite (TTM) ore.The residual solid wastes which are called coal sludge in this paper still discarded as waste large quantities.To explore the feasibility of using reductant, two types sludge, namely, TJ and SX, with different dosages were investigated.Results showed that process can realize coal-sludge utilization, good DRIP products obtained.The suitable dosage depended on...
