The Effect of Rock Properties on the High Stress Abrasive Wear Behavior of Steels, Hardmetals and White Cast Irons
Mining and mineral processing is a challenging field of industry for many reasons, including technological, economical, as well as political aspects. The market prices are constantly changing, many of the mines are located in politically unstable areas, environmental issues are becoming more and mor...

Mining and mineral processing is a challenging field of industry for many reasons, including technological, economical, as well as political aspects. The market prices are constantly changing, many of the mines are located in politically unstable areas, environmental issues are becoming more and more topical, and, of course, technological requirements for the machinery used in various applications are constantly increasing. There are many ways to answer the technological challenges, and materials science is evidently one of the key areas where technological development can and must be expected. As wear of materials is a technological problem that causes huge expenses to the mining and mineral processing industry, it is only natural that this area is being under intense scientific and technological research, a part of which also this doctoral thesis is. The correct material selection for a certain wear environment will provide not only longer service intervals but also higher productivity, reduced use of energy and lower operating costs, as well as better environmental balance and lower climate impact. Despite the many changes that have taken place in mineral handling over the years, still today the significantly highest fraction of mine products constitutes mineral fuels, ferro-alloys, and other industrial minerals. All these product lines are very different from each other, and therefore the material selection suitable for one type of production may not be applicable to the other ones.
