Grinding is a widely used way to improve the activity of SS. The low efficiency grinding is the most expensive cost item in the process [ 30 ]. At the same time, because SS contains some hard-to-grind minerals, such as iron, calcium ferrite, and magnesium ferrite, considerable energy is wasted in the comminution of such minerals.
The depletion of the richest ore deposits and the increase in number of mining projects involving deposits with complex mineralogy, higher competence and lower grade has led to an eminent need for ...
Present investigation includes the magnetizing roasting of low-grade iron ore fines followed by grinding and beneficiation using magnetic separation. The hematite iron ore used in the investigation contains 53.17% T Fe, 10.7% SiO2, and 4.5% Al2O3. Powdered bituminous coal of 210 μm size with an ash content of 12.5% and fixed …
In the existing research, most of the heterogeneous catalysts applied in the activation of persulfate to degrade organic pollutants were synthesized from chemical reagents in the laboratory.
