Carbon budget for reclaimed post mining ecosystem. Carbon sequestration shows the removal of CO 2 from atmosphere by the way of equivalent CO 2 out of the total carbon sequestered to the reclaimed ecosystem. Therefore, an evaluation of carbon budget over a chronosequence is very essential to identify sustainable management …

Cyanide is a lixiviant, or reagent that is used to leach, often in tanks, gold from a solid matrix and form a gold cyanide complex. The gold cyanide complex is then extracted from the pulp or slurry by adsorption onto activated carbon. CIL stands for carbon-in-leach. This is a gold extraction process called cyanidation where ...
Carbon emissions' accounting boundaries. The primary task of life cycle analysis is to determine the scope of system boundaries. Starting from the whole life cycle of coal mining, this paper analyzes all activities related to greenhouse gas emissions and divides all emission activities into three categories according to emissions methods: …

De Beers has announced it is leading a research project that aims to make some of its mines carbon neutral within five years. The idea involves storing carbon through the mineralisation of kimberlite waste from the diamond extraction process. This could potentially offset up to ten times the emissions of a typical mine.

In surface mining, large machines remove the topsoil and layers of rock known as overburden to expose coal seams. A form of surface mining, mountaintop mining, is where the tops of mountains are removed, allowing for almost complete recovery of coal seams. Underground (deep) mining is used when the coal is more than 200 feet below the surface.
