1multiple correct

Which methods are used for concentration of ores? (Select all correct answers)

Show answer

Hydraulic washing, Magnetic separation, Froth flotation

Hydraulic washing, magnetic separation, and froth flotation are all methods used for ore concentration. Electrolysis is used for metal extraction, not ore concentration.

2multiple choice

In the Hall-Heroult process, which substance is used as electrolyte?

Show answer

Al₂O₃ + Na₃AlF₆ + CaF₂

In Hall-Heroult process, purified alumina (Al₂O₃) is dissolved in molten cryolite (Na₃AlF₆) with fluorspar (CaF₂) to lower melting point and increase conductivity.

3multiple correct

Which metals can be extracted by electrolytic reduction? (Select all correct answers)

Show answer

Sodium, Aluminium, Potassium

Highly electropositive metals like Na, K, Al are extracted by electrolytic reduction. Iron and copper are less electropositive and can be reduced chemically.

4multiple choice
