Hope it helps mark me as brainliest.

Answer 2

Answer: Wolframite

Explanation:

Casseterite or also commonly called as tin stone is an ore of tin known as tin oxide with the chemical formula $SnO_2$. It contains magnetic impurities of tungstates of iron and managanese and the combination is called as wolfromite. Wolframite is separated from non magnetic properties by the method of electromagnetic separation.

In this method, the powdered ore is dropped over a conveyer belt moving around two rollers one of which has an electromagnet in it. The magnetic particles are attracted by the magnetic roller. The wolframite being magnetic, fall under the magnetic roller while the ore particles fall in a separate heap away from the magnetic roller.
