How to separate a mixture of iron and sulphur? Since they are a mixture, they can be separated by simple physical methods. Using a magnet (of any kind), the black or dark grey iron, can be separated from the yellow coloured sulphur. This is because, a mixture of iron filings and sulphur can be separated by using a magnet to attract the iron.
The invention relates to a process and device for separating iron and aluminum silica slag from red mud and removing alkali metal.

The developed process of silica and iron recovery consisted of size classification, magnetic separation, and removal of impurities by leaching. A concentration of SiO2 from 33.4% to 67.0%, with 60.0% of mass reduction, was achieved by size classification. After magnetic separation, the SiO2 grade increased from 67.0% to 95.0%, in non-magnegtic ...

Calcium, magnesium and iron chlorides are soluble into water and are eliminated. Then $ce{H_2SiO_3}$ can later be heated to obtain $ce{SiO2}$ $$ce{H2SiO3 -> SiO2 + H2O}$$ This is one way for obtaining $ce{SiO2}$ from the proposed silicates. Other processes are known, using for example fluorhydric acid $ce{HF}$. But, of course, using this ...
