This should be also the case of gold mining activities and the authors should clarify what is the legal status about these wastewater discharges for the studied area. The study objectives should be clearly stated as well as the novelty of this article (comparing it to other articles published in the same field by this journal or other ...
The case study probes the Gold King Mine spill through the paradigm of the lack of trust between Native Americans and the dominant culture. It describes the actions undertaken by . 4 major actors in the event: the Environmental Protection Agency (EPA), the Gold King Mine
gold miners in the Philippines and other developing countries produces and dispose of untreated wastewater to the receiving water bodies. In this study, a field-scale filter bed system was constructed to treat heavy metal metal-laden wastewater collected from small-scale gold mining site in Paracale, Camarines Norte, Philippines.
1. Introduction. Gold is essential for social development given its unique role in modern industrials and global economy (Chen et al., 2020).However, the process of gold refining is extremely unsustainable (Chen et al., 2019) and gold mining leads to land cover and land use change such as soil pit mining and forest removal (Asner and Tupayachi, 2017).
The Gramalote mining project proposes to develop an open-pit gold mine. The ore deposit covers an area of 7.221 km2 within the central mountain range in the area. The mining potential for this mine ranges between 5 to 7 million ounces of materials, of which 3,651 million ounces are gold. The mineral exploration process
Water management in mining: a selection of case studies I n t r o d u c t i o n Water's role in mining processes In mining operations, the most important use of water is typically in mineral processing. Water is required in hydrometallurgical processes (for example, to recover gold and copper from a solution of chemicals). Water is also.
A major gold mining company was experiencing a very high turnover of pH sensors. After trying most of the major brands they were struggling to find one that worked. Due to a highly complex gold and copper ore mixing process, the presence of sulfides and fluorides produced dissolved gasses that wreaked havoc on sensors, rendering most pH sensors ...
Highly toxic cyanides are among the most persistent chemical compounds in effluents, these chemicals are used in several industrial sectors and particularly in mining industry for the extraction of gold. Cyanides frequently appear at low levels in water, deteriorating its quality. In this paper a degradation of 55.76% and 62.99% was obtained using TiO2 catalyst and TiO2
