Iron Production Chemistry LibreTexts. The production of iron from its ore involves an oxidation-reduction reaction carried out in a blast furnace. Iron ore is usually a mixture of iron and vast quantities of impurities such as sand and clay referred to as gangue. The iron found in iron …
Red mud was specifically considered for its high content of iron oxide to verify the role of magnetite. For the sake of simplicity, the waste/glass proportions were kept at 70/30 (wt.%). Figure 8 a (secondary electron image, evidencing morphological details) shows that although less homogeneous, foams could be achieved again by weak alkali ...
In this study, segregation roasting and magnetic separation are used to extract nickel from a garnierite laterite ore. The garnierite laterite ore containing 0.72% Ni, 0.029% Co, 8.65% Fe, 29.66% MgO, and 37.86% SiO2 was collected in the Mojiang area of China. Garnierite was the Ni-bearing mineral; the other main minerals were potash feldspar, forsterite, tremolite, halloysite, quartz, and ...
