1. Introduction. Metals are essential in the transition to the green technologies e.g. in low emission electric vehicles and in energy storage systems (Upadhyay et al., 2021).At the same time with the positive contribution to the society, mining also produces significant amounts of solid waste (Edraki et al., 2014) belonging with millions of tons …

Considering the continuous increase in production costs and resource optimization, more than a strategic objective has become imperative in the copper mining industry. In the search to improve the efficiency in the use of resources, the present work develops models of a semi-autogenous grinding (SAG) mill using statistical analysis and …
Despite the interest in investigating mine-to-mill integration at individual gold mines (Bamber, 2008, p. 5; Grundstrom et al., 2001), information on ore loss and dilution is relatively scarce as few reliable works have been documented that are applicable to conditions in South African gold mines (Onederra, 2004, p. 1). Moreover, very few ...

For underground mines the following relationships may be used to estimate the number of mine personnel required for mines using various mining methods (Fig. 6.3.2).T is the short tons of ore mined per day, W is the average stope width in feet, and Nmn is the number of persons required by the mine. Nmn = 8.0 TO.7/WO.5 for unmechanized square

The quantity of ore mined and waste rock (i.e., overburden or barren rock) removed to produce a refined unit of a mineral commodity, its rock-to-metal ratio (RMR), is an important metric for understanding mine wastes and environmental burdens. In this analysis, we provide a comprehensive examination of RMRs for 25 commodities for 2018. …
