TL;DR: In this paper, the authors investigated the relationship between mining revenue, government consumption, exchange rate and economic growth in Botswana and concluded that although mining sector has a significant role in the economy of Botswana, it is necessary for the government to adopt further structural reforms that promote non-mining sector development to diversify the export.

TL;DR: In this paper, a material flow accounting model using input-output technique is developed for Japanese metal flows, which can be easily integrated with the MIOT (Monetary Input-Output Table) for further simulation.

TL;DR: In this paper, a predictive model for acid mine drainage and the neutralization process was constructed based on geochemical modeling, assuming first order kinetics for the dissolution of several minerals. And the model effectively predicted AMD composition after termination of mining and was also useful for estimating future neutralizer requirements and sludge volumes.

TL;DR: In this article, the authors developed a mineral resource balance model to assess sustainable supply for such as copper, zinc, and lead up to 2150, which is distinct in the long term and global level, modeling both supply and demand sides in various mineral resources by applying linear programming to minimize discounted sum of overall system cost of the resources.

TL;DR: In this paper, the authors explored appropriate environmental indicators of mining activities that might be easy to account for and deemed suitable as a first-order estimation of overall environmental impacts, which is a topic of urgent discussion in sustainable natural resource use/management.
