Special Issue Information

Dear colleagues,

Mineral processing is a crucial part of the production of our natural resources and determines the efficiency of mining processes. Together with metallurgical processes, it delivers the main elements to national industry in a suitable form. Such processes as crushing, grinding, screening and various sorts of classification are the main technological processes, usually characterized by significant costs and environmental impact. Furthermore, the amount of natural resources is limited and it is important to recover them as well as possible. The growing demand for materials, especially for those qualified as strategic or critical materials, means that the appropriate selection of technological processes is very important, especially with regard to their capacity and the efficiency of gaining materials from both primary and secondary sources. For this reason, the influence of these processes on the economy, waste production and the natural environment is a very important issue. As a result, constant optimization should be the goal of all mineral processing and metallurgical plants.

The key objective of Minerals Engineering Conference 2019—which is at the same time 15th International Conference of Non-Ferrous Ores Processing, the 56th Seminar on Physicochemical Problems of Minerallurgy, and the 24th International Conference of Mineral Processing—is to share the latest developments in mineral processing, minimization of waste production, post-production waste management, process modeling and optimization, new technologies and others aspects supporting the current needs and expectations of manufacturers and society. The main topics of the conference are:

  • analytical techniques and applied mineralogy
  • automation and process control
  • comminution, classification and sorting
  • froth flotation
  • solid-liquid separation
  • gravity concentration
  • magnetic and electric separation
  • hydro- and biohydrometallurgy
  • extractive metallurgy
  • recycling and mineral waste
  • modification of mineral properties
  • environmental aspects of mineral processing

We invite professionals from mineral processing and metallurgy, producers of equipment and software providers, people from research institutes and scientific university staff to attend the conference. We cordially invite you to join us at the conference and also to submit the extended version of your manuscripts to this Special Issue.

The aim of the paper is an assessment of geometrical properties of regular and irregular particles of chalcedonite enrichment products carried out in a laboratory ring jig. The investigative program included experiments of aggregate enrichment, along with visual analyses made for the obtained products, separately for regular and irregular particles. Several shape coefficients were calculated, and the most effective ones in terms of assessment of particle regularity were selected from among them. Particle size distributions for feed and enrichment products were also determined using the idea of minimum Feret’s diameter, and the intensity of dust emission by individual products was measured as well. The results obtained by the visual system were discussed in the context of their application in the assessment of enrichment operations carried out in a water jig. Full article

Research on the Production of Composite Fuel on the Basis of Fine-Grained Coal Fractions and Biomass—The Impact of Process Parameters and the Type of Binder on the Quality of Briquettes Produced

This paper presents the partial results of a study on obtaining compacted fuel from fine-grained coal fractions and biomass. The aim of the study was to determine the impact of selected parameters of the extrusion process and the applied binder (mechanical durability and density of the products). The fuels were formulated using the extrusion process. Raw materials used in the research were: Fine-grained coal (flotation concentrates), biomass (hydrolytic lignocellulose), and a wide spectrum of organic and mineral binders and their compositions. During the investigations, the variable factors were the following: Extrusion pressure, preparation of the mixtures for extrusion (mixing time and temperature of the mixture), composition of the extruded mixtures (share of fine-grained coal and biomass and type of binder). It was found that it is possible to extrude mechanically durable briquettes from mixtures containing fine-grained coal products and biomass. Under the conditions of the experiment, the most favorable mechanical durability was characterized by briquettes containing in their composition 90% of coal and 6% of biomass (in relation to the dry state). The briquettes with the most favorable physico-mechanical properties were obtained using organic binders—Starch (based on wheat and potato starch) and cellulose derivatives. Full article
