These releases can happen naturally. Both volcanoes and forest fires send mercury into the atmosphere. Human activities, however, are responsible for much of the mercury that is released into the environment. The burning of coal, oil and wood as fuel can cause mercury to become airborne, as can burning wastes that contain mercury.

Mining produces mainly tailings (the waste materials left after the valuable ore is separated out) and overburden (the waste materials removed to reach the ore). During the mining process, water within and around the mine is usually contaminated, so treating the mine water before it is discharged back into the environment is a major issue [2].

Jun 15, 2008· Answer. Limestone is mostly made up of the mineral calcium carbonate (CaCO3). This is not very soluble, so rocks don't dissolve very quickly. But if you add an acid, you add hydrogen ions (H+), which will react with the carbonate to form hydrogen carbonate HCO3 ions, which are very soluble in water, and the limestone will dissolve.
