Question

Ore at Akhil has acid gangue, Ore at nikhil has basic gangue. Select preferable flux for them.

Answer 1

Answer:

Akhil may use a basic flux like CaO.

Nikhil may use an acidic flux like silica.

Explanation:

The metals are extracted from ore by removing impurities from them. The impurities are known as gangue particles. The gangue particles are removed by adding flux.

There are two types of gangue particles: acidic and basic

For acidic gangue we add basic flux resulting in formation of slag.

For basic gangue we add acidic flux resulting in formation of slag.

Akhil may use a basic flux like CaO.

For example:

$SiO_{2}[acidicgangue]+CaO[basicflux]--->CaSiO_{3} [slag]$

Nikhil may use an acidic flux like silica.

The reactions are:

$SiO_{2}[acidicflux]+FeO[basicgangue]--->FeSiO_{3} [slag]$
