A facile route for simultaneous activation and separation of boron and iron from ludwigite ore at low temperature under the synergistic effect of microwave heating and sodium carbonate (Na 2 CO 3) was reported.It was shown that the composite system would absorb microwave energy well and promote the reduction of iron oxides and formation of water …
The elemental composition of the iron ores is shown in Table 2.The iron oxide (Fe 2 O 3) fraction in the ores ranges from 82 wt% (Densinox) to 95.7 wt% (Micafer).SiO 2, Al 2 O 3 and CaO, as main impurities, are present in different proportion for each material. It can be seen that the amounts of SiO 2 and Al 2 O 3 in the samples decrease for increasing values of Fe 2 …
Iron ore is an important raw material for iron and steel production enterprises. After crushing, grinding, magnetic separation, gravity concentration etc, gradually we can get iron from natural minerals (iron ore). It is the mineral aggregates …
The beneficiation process aims to increase the iron content and reduce impurities in the ore, resulting in a higher-quality concentrate suitable for further processing and utilization. The specific beneficiation method employed depends on factors such as the mineralogy of the ore, the presence of specific impurities, and the desired iron ...
Jigging process. Jigging process is an ore concentration process which is carried out in any fluid whose effectiveness depends on differences in the density of the granular mineral particles. It consists of …

Sulfidation of nanoscale zerovalent iron (nZVI) can enhance particle performance. However, the underlying mechanisms of nZVI sulfidation are poorly known. We studied the effects of Fe2+ on 24-h dynamics of nZVI sulfidation by HS– using a dosed S to Fe molar ratio of 0.2. This shows that in the absence of Fe2+, HS– rapidly adsorbed onto nZVI particles and reacted …
