However, gold is produced in much smaller quantities, so the total environmental footprint for global gold production is smaller than some other commonly used metals, including steel, copper and aluminium. The stages that contributed the most to golds environmental impact were mining and comminution (crushing and grinding of the ore).

Additionally, the significant of environmental impact has been assessed using MCDM based on SAW techniques. Materials and Methods. In the present study the SAW method was used to assess environmental impact assessment of mining activities in the study area, and TOPSIS method was applied to select the best location for the dumping site.
Keywords: Gold Mines, Pollution, Heavy metals, mining. INTRODUCTION Mining is one of the activities of human that puts a negative impact on the quality of the environment. Mining is the main source of destruction of natural ecosystems that is done by soil and vegetation removal, as well as burial under the waste disposable sites.

#0183;#32;Mining is widely regarded as having adverse effects on environment of both magnitude and diversity. Some of these effects include erosion, formation of sinkhole, biodiversity loss and contamination of groundwater by chemical from the mining process in general and openpit mining in particular.
Cyanide, mercury, and other toxic substances are regularly released into the environment due to dirty gold mining. Toxic Waste. Modern industrial gold mining destroys landscapes and creates huge amounts of toxic waste. Due to the use of dirty practices such as open pit mining and cyanide heap leaching, mining companies generate about 20 tons of

November 24, 2020 Ottawa Impact Assessment Agency of Canada. The Impact Assessment Agency of Canada (the Agency) is holding a public comment period as part of the postdecision phase for the Hardrock Gold Mine Project, an openpit gold mine and onsite metal mill located approximately five kilometres south of Geraldton, Ontario.. In December 2018, the Minister of Environment and
Environmental impacts of mining can occur at local, regional, and global scales through direct and indirect mining practices. Impacts can result in erosion, sinkholes, loss of biodiversity, or the contamination of soil, groundwater, and surface water by the chemicals emitted from mining processes. These processes also have an impact on the atmosphere from the emissions of carbon which have

Open pit mining, where material is excavated from an open pit, is one of the most common forms of mining for strategic minerals. This type of mining is particularly damaging to the environment because strategic minerals are often only available in small concentrations, which increases the amount of ore needed to be mined.
and around the largescale openpit mining . Environmental Impact Assessment (EIA) is a The negative impacts of mining on the environment are usually critical and visible.

Environmental Impact Overview Gold mining in Penhalonga represents all methods of gold extraction from deep underground mining, to smallscale mining with mines only a few metres deep, through largescale alluvial mining and the most infamous gold panning. The area therefore is affected by the environmental impacts of each of these
The environmental impact of gold production. New researchhas assessed the environmental impact of gold production using life cycle assessment and estimated embodied energy and greenhouse gases, embodied water and solid waste burden that each tonne of gold produces, using various processes. The environmental impact of gold production.
