Methods of Separation: Filtration, Distillation, Decantation - Embibe

Decantation is a process of pouring out the top layer of liquid into a separate container leaving behind the solid particles or sediments at the bottom. For example, 1. In cleaning rice and pulses, the pouring out of dirty water containing impurities is called decantation. 2. Decantation is also used to separate water after boiling the vegetables.

Separation of Copper-Nickel by Flotation and Magnetic Methods

Saturated lime solutions demonstrate a pH level of 12.4 to 12.5. Since nickel sulfide depression is highest at this pH level, most testing was carried out in saturated lime water. At pH 12.4, KEX did not float the copper sulfides. When flotation was carried out at lower pH's (8 to 10), the separation of copper from nickel was not sharp.

The function of frothers in flotation is that of building the froth which serves as the buoyant medium in the separation of the floatable from the non-floatable minerals. Frothers accomplish this by lowering the surface tension of the liquid which in turn permits air rising through the pulp to accumulate at the surface in bubble form.
