“…However, a wide range of efficiency values was discovered in Ecuadorean, Bolivian, and Canadian mines. These findings are analogous to those of other researchers who discovered significant technological gaps between mines and locations [14]. Mines in the United States, Russia, and other locations, for example, have lower technical efficiency, which could be attributed to lower ore grade, as well as differing operating environments and technologies.…”

“…Other studies used either mine-level or aggregate data to investigate the efficiency and productivity of specific commodities [14,29,35]. de Solminihac et al, used the Solow residual approach to compute the TFP of the Chilean copper sector and concluded that the rising input costs and declining ore quality reduced labour productivity [34].…”

“…Mining operations' efficiency can also be influenced by the different operating environments, such as open-pit and underground operations [44]. For instance, Ahmad et al, find that open-pit mines appear to be more efficient, perhaps due to the operations' scales, which help to increase the mine-level productivity [14].…”

“…Several factors influence mining industry productivity and efficiency, including management approaches, effective resource allocation, scale economies, and, most importantly, innovation [13]. Embracing new technologies and optimal management practices also significantly influences the efficiency and productivity of the mining industry [14]. Automation and advancements in robotics technology, for instance, contribute to decreases in carbon emissions and increases in mining industry productivity [10].…”

Innovation and technology are important tools for delivering efficiency and productivity improvement in the minerals sector. The uptake of technologies has proven to be an important lever for increasing the productivity of the mining sector. This paper provides a comprehensive analysis of mine-level productivity using global data of copper, gold, and platinum from 1991 to 2020. Various drivers of productivity have been analysed to draw policy insights. Empirical findings reveal significant disparities in terms of technical efficiency and productivity across mines and regions. The further decomposition of total factor productivity (TFP) into its different components suggests that the adoption of innovative practices and investment in technology adoption could improve the overall productivity of these commodities sectors. Our findings also suggest that an appropriate input mix and optimal scale of production could boost platinum mining productivity. Regional disparities in the productivity of different commodities sectors (e.g., South Africa vs. Zimbabwe) give policymakers insights into how to support production scale and productivity through appropriate input mixes.
