Different types of separation methods for minerals
Froth flotation dates back to the late 19th century and was the first method developed by the mining industry to separate minerals from ore. Froth Flotation, which is also used in the paper recycling and waste-water treatment industries, works on the principles of density as well as the water properties of mineral particles.

Separation techniques mineral processing Flotation. Flotation is a gravity separation process which exploits differences in the surface properties of particles. Gas bubbles are generated in a liquid and become attached to solid particles or immiscible liquid droplets, causing the particles or droplets to rise to the surface.

Apr 03, 2022 GRAVITY SEPARATION (HYDRAULIC WASHING): In this method, the light (low specific gravity) earthy impurities are removed from the heavier metallic ore particles by washing with water. It is therefore, used for the concentration of heavier oxide ores, like hematite (Fe2O3), tinstone (SnO2), and gold (Au).

Heavy Mineral Analysis Technique Heavy mineral
The separation of heavy minerals from the majority of light minerals is done by immersion in a heavy liquid with a specific density of 2.8g/ml. Cleaning Before starting the actual separation process, the samples need to be cleaned. Adhering clays or cement are removed in an ultrasound bath by adding a dispersant like sodium metaphosphate.
