Gold extraction Wikipedia

Gold extraction refers to the processes required to extract gold from its ores This may require a combination of comminution mineral processing hydrometallurgical and pyrometallurgical processes to be performed on the ore Gold mining from alluvium ores was once achieved by techniques associated with placer mining such as simple gold panning and sluicing resulting in direct recovery of

Introduction to Mineral Processing

Introduction to Mineral Processing Froth Flotation Froth flotation is considered to be the most widely used method for ore beneficiation In ore beneficiation flotation is a process in which valuable minerals are separated from worthless material or other valuable minerals by inducing them to gather in and on the surface of a froth layer
