Methods to Separate Metal From Ore - Geology ScienceBriefss
Liquation is a metallurgical method for separating metals from an ore or alloy. A mixture of metals is melted together with a third, after which the mixture is separated by liquid extraction. This method was largely used to separate silver from copper using lead, but it can also be used to remove antimony minerals from ore, and refine tin.

Iron Ore Beneficiation Technology By Electrostatic
There are usually three stages in iron ore production: mining, using a blast and removal technique, processing, and pelletizing, which turns ore into pellets the size of marbles. Processing increases the iron content while reducing the gangue in ore minerals, ensuring the correct grade and chemistry are achieved prior to the pelletization process.
