Application: Flotation process to separate valuable minerals
Flotation is a widely used process for separating valuable minerals from their ores. The method relies on the ability of certain minerals to attach to air bubbles, while other materials remain submerged in water. By adding specific chemicals known as reagents, the process can be optimized to improve the recovery and grade of valuable minerals.
