Pollution problems in the metallurgical industry: A review

pollution problems in the metallurgical industry: a review

processing of minerals and production of metals has increased greatly in recent years. as a result, the quantities of waste material and pollutants have also increased. in many cases technology has changed to cope with the problem. processes have been either modified to decrease emissions, or replaced by others that are less polluting even if at a higher cost. this paper briefly reviews example...

Algorithmic Solutions to Some Transportation Optimization Problems with Applications in the Metallurgical Industry

In this paper we address several constrained transportation optimization problems (e.g. vehicle routing, shortest Hamiltonian path), for which we present novel algorithmic solutions and extensions, considering several optimization objectives, like minimizing costs and resource usage. All the considered problems are motivated by practical situations arising, for instance, in the mining and metal...

Regional Distribution of the Metallurgical Industry in the Czech Republic

T. Sadilek, University of Economics, Faculty of International Relations, Prague, Czech Republic The aim of the article is to present the regional distribution of the metallurgical industry in the Czech Republic and to describe the specific factors which determine the localization of the industry in Czech regions. In order to achieve that goal, traditional tools of regional analysis are used, su...

Options of Utilising Steelmaking Dust in a Non-metallurgical Industry

Recycling of by-products of the steelmaking process in electric arc (EAF) furnaces is an important activity from the perspective of environmental protection as well as the steelmaking industry itself. This article is a discussion concerning the selected research results in terms of utilisation of steelmaking dusts containing 4 12 % of zinc in manufacture of cement bricks, ceramic construction m...
