Gravity separation is one of the oldest technique in mineral processing but has seen a decline in its use since the introduction of methods like flotation, classification, magnetic separation and leaching. Gravity separation dates back to at least 3000 BC when Egyptians used the technique for separation of gold.
Cyclone in Operation. The hydrocyclone operation consist of having the ore slurry pumped into its feed inlet, the ore is then separated by size with the fine material coming out of what is referred to as the “OVERFLOW” via a Vortex Finder. The mineral that still requires grinding is named ← Read The Full Metallurgy Article

Wills' Mineral Processing Technology: An Introduction to the Practical Aspects of Ore Treatment and Mineral Recovery. has been the definitive reference for the mineral processing industry for over thirty years. This industry standard reference provides practicing engineers and students of mineral processing, metallurgy, and mining with
Mineral Mineral Classification of minerals: Since the middle of the 19th century, minerals have been classified on the basis of their chemical composition. Under this scheme, they are divided into classes according to their dominant anion or anionic group (e.g., halides, oxides, and sulfides). Several reasons justify use of this criterion as the distinguishing factor at the highest level
3.4.1. Classification and regression trees. The Classification and Regression Trees (CART) is a supervised machine learning algorithm proposed by Breiman et al. in 1984 (Kelleher et al., 2015). It represents a binary decision tree constructed from the training dataset in a recursive way.
This is a practical course in mineral processing, designed for engineers, technicians, operators, support staff and others working in the mineral processing industry but with no prior training in this area. The course reviews fundamental principles, conventions and terminology, and provides a broad overview of current technical and operating issues and circuit design considerations.
