Environmental impact of mining Wikipedia

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

A Life Cycle Assessment study of iron ore mining

Dec 01, 2015· The results also show how mining can influence the production chain of its inputs and impacts associated with this chain. For example, the area required to obtain some inputs such as starch is as significant as the area needed for ore mining and tailings dams. That is, many times, the lower use of inputs can be more significant for

Influence of ore processing activity on Hg, As and Sb

May 01, 2018· The present study was realized with the main objectives of: i) defining the influence of different ore processing activities such as ore crushing, sieving and drying, cinnabar roasting, Hg distillation and mining waste disposal in dumps, on contamination and fractionation patterns of Hg, As and Sb; ii) assessing the behaviour of these heavy

Mining Underground mining Britannica

Mining Mining Underground mining: When any ore body lies a considerable distance below the surface, the amount of waste that has to be removed in order to uncover the ore through surface mining becomes prohibitive, and underground techniques must be considered. Counting against underground mining are the costs, which, for each ton of material mined, are much higher underground than on the

Ore Dilution & Recovery in Mining

Recovery and dilution usually are interrelated; with some methods of stoping a high recovery involves contamination of the ore from the walls or capping, and often clean ore can be obtained only by leaving some ore in the mine. In open-stope mines the greatest loss of ore is that tied up in pillars left for support of the back or hanging wall. The amount of ore thus left varies considerably

1.1 PHASES OF A MINING PROJECT

waste called ‘tailings,’ the residue of an ore that remains after it has been milled and the desired metals have been extracted (e.g., with cyanide (gold) or sulfuric acid (copper)). If a mining project involves the extraction of a few hundred million metric tons of mineral ore, then the mine project will generate a similar quantity of

What are the main methods of mining? American

There are four main mining methods: underground, open surface (pit), placer, and in-situ mining. Underground mines are more expensive and are often used to reach deeper deposits. Surface mines are typically used for more shallow and less valuable deposits. Placer mining is used to sift out valuable metals from sediments in river channels, beach sands, or other environments.
