Abstract

In Kazakhstan, in-situ recovery (ISR) mining utilizes H2SO4 (pH < 2) to mobilize uranium from naturally reducing conditions. ISR can be less environmentally impactful than physical mining techniques, but it risks groundwater (GW) contamination. Presented here is a geochemical and metagenomic analysis and comparison of pre-, mid-, and post-mining GW conditions. Biostimulation may limit the spread of U and decrease the time of exposure, compared to natural attenuation, by orders of magnitude

Environmental effects of mining

Environmental effects of mining can occur at local, regional, and global scales through direct and indirect mining practices. Mining can cause in erosion, sinkholes, loss of biodiversity, or the contamination of soil, groundwater, and surface water by chemicals emitted from mining processes. These processes also affect the atmosphere through carbon emissions which contributes to climate change.

Groundwater pollution

Groundwater pollution (also called groundwater contamination) occurs when pollutants are released to the ground and make their way into groundwater. This type of water pollution can also occur naturally due to the presence of a minor and unwanted constituent, contaminant, or impurity in the groundwater, in which case it is more likely referred to as contamination rather than pollution.

Mountaintop removal mining

Mountaintop removal mining (MTR), also known as mountaintop mining (MTM), is a form of surface mining at the summit or summit ridge of a mountain. Coal seams are extracted from a mountain by removing the land, or overburden, above the seams. This process is considered to be safer compared to underground mining because the coal seams are accessed from above instead of underground. In the United States, this method of coal mining is conducted in the Appalachian Mountains in the eastern United States.
