Opis:: The consumption of energy contributes significantly to the overall cost of operations and the environmental impact of the mining and mineral processing industry. However, despite a few notable exceptions, most of the resulting waste heat produced is dissipated, without recovery, into the environment. There is also a lot of stored heat in mine water which can be tapped into long after a mine has closed. There is, therefore, significant opportunity to improve the industry's sustainability through increasing the amount of waste heat recovered and repurposed.

Opis:: Artisanal and small-scale mining (ASM) - small sized, largely unrecognized, rudimentary, and an informal form of mining - occurs in more than 70 countries around the world and is mainly hailed for its socioeconomic benefits and reviled for its environmental devastation. As a result, many people are confused about the future of ASM. In Ghana, the government banned ASM in 2017 and formed a security taskforce drawn from the military and police to crack down on nomadic and local ASM workers who defy the ban. This approach is unsustainable, deals less with the fundamental problems, and increases poverty among the already impoverished local populations who depend on this type of mining as their only means of livelihood. To support the argument for sustainable reforms, revenue growth decomposition and growth accounting analyses were performed to determine the factors shaping ASM revenue over 25 years (1990-2016). Results show that production (gold output) is the most important factor that influences revenue growth from ASM, contrary to the usual view that the price of the metal is mainly responsible for the increase in revenue. Thus, increasing labor hours in ASM could significantly increase mining revenue, reduce unemployment, and improve local commerce. We strongly conclude that sustainable reforms such as increasing local participation in decision making, education and training, adoption of improved technology, strengthening regulatory institutions, legislation and enforcement of enactments, and the provision of technical support and logistics could ensure socio-environmental sustainability.

Opis:: This paper presents the results of an investigation carried out on the impacts of cobalt extraction process using a life cycle assessment by considering a cradle-to-gate system. Life cycle inventory data was collected from the EcoInvent and Australian Life cycle assessment database (AusLCI) and analysis were performed using SimaPro software employing the International Reference Life Cycle Data System (ILCD) method, and Cumulative Energy Demand method (CED) for per kg of cobalt production. Several impact categories are considered in the analysis i.e. global warming, ozone depletion, eutrophication, land use, water use, fossil fuels, minerals, human toxicity, ecotoxicity, and cumulative energy demand. The analysis results indicate that among the impact categories, eutrophication and global warming impacts are noteworthy. Medium voltage electricity used in cobalt production and the blasting operation appears to be causing most of the impact and emission into the environment. The sensitivity analysis was carried out using three different case scenarios by altering the electricity generation sources of UCTE (Synchronous Grid of Continental Europe) to investigate the proportional variation of impact analysis results. Furthermore, the impacts caused by cobalt production are compared with nickel and copper production processes to reveal their relative impacts on the environment and ecosystems.
