Energy and greenhouse gas impacts of mining and mineral processing

Transparency on greenhouse gas emissions from mining to enable climate change mitigation. M. Azadi S. Northey Saleem H. Ali M. Edraki. Environmental Science. 2020. The climate change impacts of mining are often not fully accounted for, although the environmental impact of mineral extraction more generally is widely studied.2.1 Energy. Rock drilling, blasting, and comminution (crushing and grinding) consume a vast amount of energy in hard rock mines. As mentioned in Sect. 1, statistics from hard rock mines indicates that drilling and blasting consumes 2% and comminution does 53% of the total energy input in the whole production chain from Reduction of Fragment Size from Mining to Mineral Processing

OVERVIEW OF THE IMPACT OF MINING ON THE IIED

On the basis of these impacts, mining and mineral processing operations could be classified into high impact,<br /> medium impact and low impact, as shown in Table 1.3. These descriptors were then used in descriptions of the<br /> scale and variety of impacts linked to mining activities in each of the sub-catchments.<br /> xxvAn LCA model has been developed to analyze the environmental impacts, with respect to the defined functional unit of mining and processing one tonne of ore, from all the core processes involved through ore extraction and mineral processing stages up to transportation of concentrates to off-site refining facilities (Fig. 1).Download : Download Environmental impact improvements due to introducing automation

Evidence of the impacts of metal mining and the effectiveness of mining

Mining activities, including prospecting, exploration, construction, operation, maintenance, expansion, abandonment, decommissioning and repurposing of a mine can impact social and environmental systems in a range of positive and negative, and direct and indirect ways. Mining can yield a range of benefits to societies, but it may also Abstract. Mining of iron ore is a highly capital and energy-intensive process. Life cycle assessment of the mining and mineral processing of iron ore in Australia was carried out in this chapter using SimaPro life cycle assessment software as a case study. The environmental impacts considered in the study were embodied energy and Life cycle assessment of iron ore mining and processing

Energy Efficiency Improvement in Surface Mining IntechOpen

This chapter aims to provide an overview of energy efficiency in the mining industry with a particular focus on the role of fuel consumption in hauling operations in mining. Moreover, as the most costly aspect of surface mining with a significant environmental impact, diesel consumption will be investigated in this chapter. This An exhaustive review of recent LCA studies on mining and mineral processing operations was conducted to identify how these have dealt with various methodological challenges. A total of twenty-nine studies were found, most of which focusing on developed regions and in three commodities: coal (28%), aggregates (21%), and Life Cycle Assessment in the minerals industry: Current

Coal and Other Mining Operations: Role of Sustainability

Pyrite (FeS 2) is the major sulfur mineral in coal. When coal is mined, fresh sulfur-bearing minerals in the coal and rocks are exposed to air and water. Problematic mine drainage is given many names including acid rock drainage (ARD), acid mine drainage (AMD), and mining-influenced water (MIW), among other names.The purpose of the paper is to identify factors associated with operational factor (OF), geo-environmental factor (GEF), and managerial factor (MF) from the literature. After identification, the study intended to assess the impact of geo-environmental factors and managerial factors on operational factors of the mining industry. The study also tests the Geo-environmental factors’ influence on mining operation:

Mineral Processing SpringerLink

In mineral processing, ores must go through a number of different operations to obtain the final products. Thus, mineral processing involves four major steps or stages: (1) comminution or size reduction, (2) size separation, (3) concentration or beneficiation by taking advantage of physical properties, and (4) dewatering.Dear Colleagues, Water within minerals processing is currently a highly topical issue. With so many mining operations being located in water-scarce regions as well as worldwide water shortages, tighter environmental restrictions, and developing corporate sustainability strategies, it is essential that mineral-processing operations become Minerals Special Issue : Water within Minerals Processing

Analysis of Environmental Costs’ Effect in Green Mining

Nowadays, one of the most significant problems in mining activities is the significance of analyzing environmental issues along with mining, concentration, and mineral processing operations to achieve the goals of sustainable development. Nevertheless, mine owners refuse to include environmental costs (EC) and consider them unprofitable. Due Mineral processing is the process in which chemical or physical methods are used to separate the useful minerals in the ore from the useless minerals (usually called gangue) or hazardous minerals, or to separate multiple useful minerals.
