Singh & Perwez 2015 Discovered the transportation of iron ore as the most devastating activity in Goa iron ore mining region & found the depreciation in air quality to be
To quantify this stress, we develop a set of global composite environmental, social and governance indicators, and examine mining projects across 20 metal commodities to identify the co-occurrence ...
In contrast to previous studies that have investigated iron ore mining efficiency and its determinants, this research stands out by examining the TBL dimensions—economic, social, and environmental—and their combined impact on iron ore mining efficiency in this diverse region.
Mining company Oz Minerals wants its next project, West Musgrave, to be carbon neutral. ... "Commodities like iron ore, copper, nickel, lithium, these are the commodities that will help drive the ...
The iron ore mining and dressing industry accounts for a large share of the ferrous metal mining and dressing industry, and the iron ore resource tax represents 93% of resource tax revenue obtained from the ferrous metal mining and dressing industry.
Land use change driven by mining is a major environmental concern, affecting ecology and local populations via habitat destruction, water use, and pollution. The provenance …
The environmental impacts considered in the study were embodied energy and greenhouse gas (GHG) emissions, while the functional unit was 1 ... Impact assessment of iron ore mining and processing stages.
environmental impacts of metal ore mining and iron mountain 7 of these processes is determined by the extraction process and how the material was initially fractured (Norgate & Haque, 2010).
In this study, the impacts of mining iron ore particularly resulting from open-cast mining are covered with special reference to environmental issues (such as Air, Water, Soil), and health hazards on the population of the mining region.
Appendix 2: Environmental and Social Impacts of Mining This appendix is meant to provide a brief review of the literature with regard to environmental and social impacts from mining, as well as key regulatory issues.
In recent years, changes in management techniques have efficiently minimised many negative impacts. Mining companies are also making efforts to reduce the environmental and social impacts of ...
Body of evidence, with examples, of different impacts of mining on biodiversity across spatial scales (site, landscape to region, global) and their causal pathway (defined as either a proximate cause of …
This study asks: Do environmental impacts from historic iron mining in the Mesabi Range persist? Mapping historic mining and current lake water quality within the Mesabi Iron Range suggests that they do. HUC-12 subwatersheds that experienced historical mining activity are also the subwatersheds with a greater percentage of …
For example, mining, processing and transportation require fuel and electricity, and the decomposition of carbonate minerals, employed to reduce …
Notably, major disruptions such as copper and iron mining mainly occurred in RoW America and Brazil, which had a big impact on other countries. China and RoW America were the most affected by both the overall …
This chapter identifies and explores the common environmental effects of mining in Western Australia (WA). Utilising unique state-specific data, we examine site-specific factors with reference to metals, mine life …
