What Is Beneficiation In Mineral Processing? Minerallurgy

Beneficiation means converting the mined material into a valuable product. It is the only way to exploit large deposits, even low-grade and/or complex mineralogy. It allows the mining of ores not only metal resources but all useful substances such as sands, limestone, granites, barite, fluorine, etc The species enriched constitute the concentrate, which will, in turn, be the raw material

Introduction to Mineral Processing or Beneficiation

Most rock deposits contain metals or minerals, but when the concentration of valuable minerals or metals is too low to justify mining, it is considered a waste or gangue material. Within an ore body, valuable minerals are surrounded by gangue and it is the primary function of mineral processing, to liberate and concentrate those valuable minerals.

Grade Vs Recovery In Mineral Processing Minerallurgy

But the ultimate grade of a substance in the ore is its value in the pure mineral. For example, copper grade in CuFeS2 is 34.7 per cent. We cannot go beyond this value; thus, the metal grade cannot be more than 34.7 per cent in the concentrate. Mineral processing engineering aims to move this shape to achieve both maximum grade and recovery.
