May 27, 2020· Owned and operated by Boliden Kevitsa Mining Oy, Kevitsa mine's production is approximately 40 Mtpa, including 8 Mt of ore containing nickel, copper, gold, platinum and palladium. In 2016, Boliden Group acquired the Kevitsa operation and fragmentation was identified as one of the key performance indicators to evaluate several productivity ...
Efforts to maintain effective drilling and rock fragmentation by reducing the blasthole grid are necessary as a result of the hardness of the rock mass. Therefore, a grid of 4.5mx4.5m (Figure 16.2) is used for waste and, generally, a denser grid of 3.5mx3.5m is used for ore to achieve greater fragmentation.

This paper presents the results from the investigation of the application of thermal fragmentation in Australian hard rock underground narrow-vein mining. Two geologically similar samples from an underground narrow-vein hard rock gold mine were collected to obtain a measure of the technology's ability to recover ore by the creation of large thermal openings to assess the applicability of the ...
Quebec explorer and developer Nippon Dragon Resources has announced that it is restarting development work at its Rocmec 1 gold property, which it will use as a showcase for thermal fragmentation technology. The company will employ its patented mining method at Rocmec 1, as well as conventional mining methods as warranted.

1. Introduction. Mining is an extensive driver of land use change. Although mines occupy less than 1% of Earth's land surface (Hooke et al., 2012), mining and mineral processing can influence landscapes far beyond the site of mineral extraction.Mining projects can pioneer investments in pristine regions and, by establishing infrastructure and facilitating access to previously undisturbed land ...
A fragmentation study was carried out for the New Afton B1 and B2 caves to generate fragmentation models that could be applied to future lifts. In part 1 of this paper, implications of fragmentation size for the mine are considered, whereas the effects on mill performance are addressed in part 2.
