7 iii Chapter 1 Introduction In minerals processing, screening is considered the simplest and most convenient method of sizing particles. Simply, in this context, screening involves separating particles of an ore ac- cording to size and, often, geometry. This is the primary reason why screening is performed. The screening process typically follows after comminution processes such as primary

Introduction to Mineral Processing or Beneficiation

The vibratory screen is probably the most common screening device found in mineral processing applications. Different manufacturers have developed unique vibration and motion systems for the various types of material and particle sizes encountered within mineral processing plants. Many of these types of screens have multiple decks so different particle size products can be obtained from a

THE PURPOSES OF SCALPING IN MINING Hawk

As a first-cut first line of defense, scalping in mining acts as the leading edge of the mining process, one that also introduces the first-cut to a cursory screening cycle. The toughened machinery defuses the high-tonnage stream while simultaneously removing coarse matter and unprocessable detritus. It also makes for a fine "riprap" solution, a machine that sorts sizeable chunks of rock so that they can be used for
