The value chain of metal production consists of a number of processing steps that result in obtaining the final metal product from the given raw material
The results show that nearly 30% of tions according to specific countries are presented in Table 1, where the top 10 countriers the world’s publications regarding mechanical processing technology of raw materials with the most publications are shown
The results can contribute to a better understanding of selected mechanisms relating to dynamic breakage, such as the probabilities of establishing the given size of particles and their location within the crushed product. Papers included in this Special Issue of Minerals, entitled “Advanced Techniques and Efficiency Assessment of Mechanical Processing” addressed significant problems related to the processing of raw materials that can be grouped into the following categories:
Summary
Processing”—Editorial Note and Critical Review of the Problems. Publisher’s Note: MDPI stays neutral with regard to jurisdictional claims in published maps and institutional affiliations. Its main duty is to provide material of a sufficient size, and generate an acceptable level of useful mineral liberation This allows the required results to be achieved in downstream beneficiation operations, which are measured through the recovery of useful metals and the level of pay metal loss in tails. The aim of mechanical processing is, to provide a sufficient size reduction in material by dividing it into particles or fragments, which are measured using the comminution ratio level. All of these operations aim to remove impurities and other unwanted fractions from the feed, which is mainly applied to the aggregate production sector. Achieving the required technological outputs measured through the obtained size reduction in the feed material and specific particle size composition; Economical assessment of the real and potential effects through the analysis of the relationship between costs and benefits; Environmental and social aspects resulting from a general negative impact of mining on the environment and society; Application of optimization approaches and methods, together with simulation models based on theories of mathematical and statistical modelling; Other approaches not listed above or a combination of several scopes
