TL;DR: In this paper, the impact of wear on the global energy consumption due to friction and wear in the mineral mining industry is investigated, and the authors present a detailed analysis of a large variety of mining equipment used for the extraction, haulage and beneficiation of underground mining, surface mining and mineral processing.

TL;DR: In this article, the authors identified challenges related to adopting novel business models, data collection and management, collaboration and competence requirements, and virtualization of products and processes, collaboration with stakeholders and utilising digitalization were highlighted to be major opportunities in adopting CE-based business models.

TL;DR: In this article, the authors evaluate the abrasion resistance of tool steel matrix-based composites having different micro-structures and find out whether the simple dry sand rubber wheel abarasion test (ASTM G 65-91), which is a commonly used and relatively cheap and easy to perform test, could be used to rank materials for rock crushing.

TL;DR: A high speed slurry-pot wear tester was developed for close-to-reality heavy-duty wear testing of materials used in mineral applications as mentioned in this paper, where samples are attached on four levels in a pin mill configuration.

TL;DR: In this article, a sample rotation test method was developed for testing of materials used in mining and other mineral handling applications, where the samples are attached to a vertical rotating shaft on four levels in a pin mill configuration.
