2019-11-25The crushing and grinding (comminution) of mineral processing has the objective of separating the ore min-erals from the waste, generally referred to as gangue. To effect separation, the mined ore is finely crushed to lib-erate individual ore mineral grains to enable concen-tration of the sought after ore minerals. The very fine

Erosion and Sedimentation

Erosion in the context of soil and watershed conservation is the detachment and movement of soil particles by natural forces, primarily water and wind. More broadly, erosion is the process of wearing away rocks, geologic, and soil material via water, wind, or ice (e.g., glaciers).

Anthropogenic Activity

Anthropogenic activities are responsible for an intensive emission of greenhouse gases to the atmosphere, contributing to an increase of 35% of carbon dioxide (CO 2, one of the most important greenhouse gases) emissions between 1990 and 2010 [1]. A large fraction of these emissions results from the combustion of fossil fuels for energy production.
