This research, aimed to determine whether the COSO (Committee of Sponsoring Organizations) ERM (Enterprise Risk Management) model, implemented in a scientific Institute of special importance to the Republic of Serbia, can identify the multiple business opportunities and prevent instabilities caused by various external factors through its strategic...

Technological advancements have led to the emergence of various devices that can enhance employee safety in the mining industry. Even though there is no true substitute for hands-on training, certain devices can improve training, thereby making the working process safer. One such device is the 360-degree camera, which can be used to create 360-degr...

The increased exploitation of ores leads to the generation of mining waste, which has a negative impact on the environment and human health. For this reason, it is necessary to take care of it in an adequate way by applying some of the possible treatments. In addition to protecting the environment by applying appropriate treatment, there is also th...

The present paper describes the technological solution for obtaining Cu, Zn, Pb, and Ag from jarosite waste raw material, with its simultaneous separation from In and Fe. By roasting at low temperatures, iron was transformed from the Fe2(SO4)3 form into Fe2O3, which is insoluble in water and slightly soluble in acid. Copper sulfate and zinc sulfate...

Coal exploitation at the Potrlica open pit of the Pljevlja Coal Mine takes place in complex structural, geotechnical, and hydrogeological conditions. They are the cause of numerous restrictions regarding the mining works, the width of the excavation front, the speed of working front progress, the speed of deepening the mine and other aspects of exp...

The mining waste, i.e., flotation tailings occurs in the flotation concentration of copper ore processing. Considering the copper content in tailings of about 0.2-0.3%, it can be seen as a potential material for the copper recovery. This paper presents the chemical characterization of sample of the flotation tailings, deposited at the Old Flotation...

The Additional Mining Design for coal exploitation at the open pit "Potrlica" - Pljevlja for the period 2020 - 2025, has defined the exploitation system important parameters and development of the open pit. Among others, for the first half of 2022, it is planned to move the crushing plant to a new position, in a direction of the excavation front. G...

In recent years, the term "industrial tourism" has been increasingly used in the literature. It describes an area that includes industrial monuments and abandoned buildings, and above all rare ones that are still in function. Industrial tourism includes all plants used for food processing, wood processing and textile industry, there are also mills,...

This work presents the application of the COMFAR III software package in development a feasibility study of investment. The application of this program enables an efficient analysis of investment justification and numerous variations of both input and graphic and alphanumeric output data. The methodological basis of economic analysis, used in this...

There are many sources to increase value in an integrated mining–metallurgy context. The optimal strategy for concentration of minerals from the ore is one of these sources. The elements of mining-metallurgy operations from resources, infrastructure, mining site, processing, and metallurgy are mutually dependent, and reinforce and interact positive...

This paper gives the selection of the optimal model of trucks for transport of coal, and seam waste at the OP Gacko in terms of selective exploitation. Mining of coal and seam waste is carried out in two exploitation zones, the central and roof zone, and the coal and waste transport and disposal is carried out to the different crushing plants and l...
