An Overview of Basic Gold Separation Methods - RareGoldNuggets

The flotation method involves mixing your crushed ore with water and then you add frothing agents in a single floatation machine. You then use a tube to release air into the floatation machine. This creates air bubbles to the bottom of the machine and this helps attach hydrophilic materials such as gold to the bubbles and thus float on the water.

Separation of Copper-Nickel by Flotation and Magnetic Methods

The separation of copper and nickel is achieved by differential flotation, if the mineral grains can be liberated by grinding. Normal practice is to depress the nickel sulfides by increasing the pH of the flotation pulp to between 9 and 11 and selectively floating the copper minerals.

Different types of separation methods for minerals

Separation occurs when the minerals are soaked in a chemical solution, causing the materials to aggregate based on whether they are hydrophobic (water-repellant) or hydrophilic (water-attracting). Froth flotation uses large amounts of water laced with chemical agents, most of which is unrecyclable.
