Semi-Smelting Reduction and Magnetic Separation for the

This work presents a semi-smelting reduction and magnetic separation process for the recovery of iron and alumina slag from iron rich bauxite ore. The effect of the process parameters on the recovery rate of iron, maximum particle size of the iron nugget, and the Al2O3 content of the alumina slag was investigated and optimized. The results Sensor-based ore sorting is a physical separation technology where the mechanical platform contributes to the overall process efficiency. The primary factor for technical feasibility is the sub-process of detection. The detection efficiency describes the chance of misclassification in dependence of the cut-off grade.Minerals Free Full-Text Sensor-Based Ore Sorting

Developments in the physical separation of iron ore:

Abstract. This chapter introduces the principle of how low-grade iron ores are upgraded to high-quality iron ore concentrates by magnetic separation. Magnetite is the most magnetic of all the naturally occurring minerals on earth, so low-intensity magnetic separators are used to upgrade magnetite ores. On the other hand, because oxidized Utilization of plentiful fine-disseminated iron oxide ores resources attracted increasing attention in these years due to the depletion of easy-dressing iron ore reserves. In this paper, an improved Fe recovery method from the refractory fine-grained iron ores was proposed, and iron can be stepwise recovered by microwave-assisted Development of roasting-acid leaching-magnetic separation

Beneficiation of Magnetically Separated Iron-Containing

study as well. The required mix was obtained as follows. The processed ore of 10 mm size with 52 percent average iron grade was crushed and ground to ( 0.1) mm size. The required quantity of 60 percent iron concentrate was produced by a multi-stage cleaner separation using the laboratory magnetic separator being studied. We note that iron grade in the feed for size fraction finer than 2360 micron equals to 45.70% Fe. Figure 5 illustrates the iron grade changes in different size fractions. As it appears from Fig. 5, for size fractions of (–2000 + 300) micron, (–300 + 37) micron, and (–37) micron, iron grade equals to 44, 48 and 40%, respectively.

Influence of Mineralogy on the Dry Magnetic Separation of

Magnetic separation is often considered pertinent for manganese ore beneficiation when the ore is abundant with siliceous rich gangue mineral phases. However, the process is deemed to be inapposite for the ferruginous type of ore, and remains a grey area of research. In the present investigation, two different types of manganese ore were A dry separator for iron ore is composed of a machine frame, an upper primary dressing unit consisting of strong-magnetic rollers, medium-speed belt ring and a strong magnetic field, a coarse ore hopper, a lower fine dressing unit consisting of week-magnetic rollers, high-speed belt ring and a weak magnetic field, an ore concentrate hopper, and a low-grade CN100998968A Iron ore dry separation machine Google
