Section snippets Ore sorting technology. Ore sorting technologies take advantage of nearly the entire electromagnetic spectrum (Fig. 3). In identifying the appropriate sensor technology to use, it is important to understand the operating principles of the sensor and the potential sorting criteria.
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. 1.3 Run-Of-Mine Material and Minerals. Generally, mineral processing begins when an ore is delivered from a mine, to a processing facility.

The first publications and investigation reports on mineral processing, as well as the metallurgical treatment of processing products of lead vanadate ores and rich lead vanadate ores, were published between 1900 and 1920 [53,54,55]. The ores were considered as a potential source of vanadium for the rapidly increasing steel industry.
gold processing, preparation of the ore for use in various products.. For thousands of years the word gold has connoted something of beauty or value. These images are derived from two properties of gold, its colour and its chemical stability.The colour of gold is due to the electronic structure of the gold atom, which absorbs electromagnetic radiation with …
Purpose The aim of this literature review is to investigate the role of the beneficiation stage in the Life Cycle Assessment (LCA) of metals and minerals with a focus on the flotation process. Methods The systematic literature search included LCA studies comprising the beneficiation stage in their system boundaries and resulted in 29 studies …
This paper outlines a framework for facilitating the formalization of artisanal and small-scale mining (ASM) – low-tech, labour-intensive mineral processing and extraction – in sub-Saharan Africa.

In the context of its processing, gold deposits are typically classified, for the purposes of simplification, as: 1) free milling, and 2) refractory ores (including complex and carbonaceous). Based on their mineralogical characteristics and their mineral processing techniques required to liberate them, however, gold ores can be classified further.
