Extraction of Metals from Ores – Different Processes Involved
This step concentrates the ore by performing the removal of impurities. It is also called ore dressing. This process is quite elaborate and is named according to the equipment or technique used. Let us take a quick look. Hydrolytic Method: In this method, the ground ore particles are poured over a vibrating table with a slope or inclination.

A Short History of Mineral Processing
To the modern mineral processing engineer crushing of ores takes place in large jaw or gyratory crushers that can handle thousands of tons per hour. Similarly grinding is conducted in huge rotary equipment charged with steel rods or cast iron balls and can render tons of peanut-sized ore particles into powder like flour in a matter of minutes.
