Processes and Procedures in the Extraction of Iron

2021-2-15 · The extraction of iron from its ores is quite a technical process. The iron ore is first roasted in air to produce iron(III) oxide which is mixed with coke and limestone and then further heated to a very high temperature in a blast furnace. These materials are loaded into the blast furnace from the top while a blast of hot air is introduced into it from beneath via small pipes known as tuyeres.

Separation of iron impurity during vanadium acid

2020-1-1 · During the direct acid leaching process, very little pyrite (the main source of Fe in black shale) was dissolved due to the preventive FeC 2 O 4 ·2H 2 O coating in the pyrite surface. Huang et al. (2016) adopted a two-stage pressure acid leaching process that effectively reduced Fe and Al levels in the vanadium leaching solutions.

In this study, oxidizing roasting, segregation roasting, and magnetic separation are used to extract cobalt and iron from refractory Co-bearing sulfur concentrate. The Co-bearing sulfur concentrate containing 0.68% Co, 33.26% Fe, and 36.58% S was obtained from V-Ti magnetite in the Panxi area of China by flotation. Cobalt pyrite and linneite were the Co-bearing minerals, and the gangue

Recovery of Lime, Sulfur, and Iron from Gypsum and

2019-5-25 · Currently, gypsum and pyrite, two major wastes generated by the coal combustion industry, have to be land-filled. The feasibility of a new approach of recovery of lime, iron, and sulfur products from these wastes is discussed in the present work. By thermal decomposition of pyrite, 42% of the sulfur is recovered and pyrrhotite is produced. A thermodynamic analysis shows that the recovery of
