Froth Flotation - Metallurgist & Mineral Processing Engineer

Grinding an has an important influence on . For optimum results, valuable minerals should be separated completely from the waste and from each other. This is often impractical and can complicate matters by creating particles that are so fine they are difficult to recover by . The ratio of to solids is very important.
