Principles of Mineral Processing by Fuerstenau, Maurice C.
It presents the principles that govern various unit operations in mineral processing along with examples that illustrate how these principles apply to real-world situations. Topics are arranged in the order of the typical processing sequence, including communition, separation, flotation, hydrometallurgy, and waste handling.
Centrifugal air classifiers offer effective fines screening
C entrifugal air classifiers are used extensively to process aggregates, foods, metals, chemicals, minerals, fly ash, ceramics and other materials. Air classifiers are used for dry processing; to effectively remove fine powders, the surface moisture of the feed must be very low.. Air classifiers work effectively on granular coarse discharge with …

Wills' Mineral Processing Technology, 8th Edition
Classification. Classification, as defined by Heiskanen, is a method of separating mixtures of minerals into two or more products on the basis of the velocity with which the particles fall through a fluid medium. The carrying fluid can be a liquid or a gas. In mineral processing, this fluid is usually water, and wet classification is generally ...
