Introduction to Mineral Processing

Introduction to Mineral Processing

Gold, silver, copper, lead, zinc, molybdenum, iron, potash, phosphate, and even sand for glass are often processed by froth flotation. Without froth flotation, many of the metals and minerals used every day in our modern world would be much more expensive. Solvent Extraction Solvent extraction is a hydrometallurgical process. The process entails
