It is expected that demand will increase to 29 Mta by 2025. As a result of the declining yield achieved by the existing copper mines, the annual demand will rise by 15 Mta. This corresponds to an average annual increase of 5.3 % as against 3 % if the production quantity of the existing copper mines remained constant.
In simple terms, mineral processing is separating commercially valuable minerals or metals from other rocks. It's not often that you dig up a large gold nugget. Instead, small particles of gold can be found mixed in with other minerals, metals, and rocks, some valuable, and some not. The collection of all these materials together is called ore.

Mineral Processing. Mineral processing is the process in which chemical or physical methods are used to separate the useful minerals in the ore from the useless minerals (usually called gangue) or hazardous minerals, or to separate multiple useful minerals. In the early years, mineral processing was called mineral concentration or …

A mineral processing circuit may consist of multiphase mass transfer, hydrometallurgical and thermal processes; these are often open to the elements and coupled to a variable and evolving feed. These challenges— tight specifications in manufacturing plants and high volume, complex circuits in mineral processing plants …
Common mineral processing problems include: Low mineral recovery. Meeting target mineral grade, especially during ore changes. Difficulty generating an optimum froth bed. Mineral crowding on bubbles. Slow flotation kinetics, leading to the target mineral being lost to coarser or finer size fractions.

This selectively liberates the valuable minerals from the waste. The waste is then removed from the comminution circuit so that only the valuable mineral ore remains in the circuit for processing. By effectively removing the waste material and creating microfractures in the valuable ore, we can achieve energy savings of up to 70%.
Haldar ( 2013) described mineral processing «as the value-added processing of raw material (run-of-mine ore) to yield marketable intermediate products (e.g. copper concentrate) or finished products (e.g. silica sand) containing more than one valuable minerals and separation of gangue (tailing).».

The objective of mineral processing is to liberate and separate the valuable minerals from the gangue. In order to separate the valuable minerals from the gangue, it is necessary to crush and/or grind the rocks to a size where they are partially or fully exposed, or "liberated". The process of crushing and grinding is referred to as ...
