Mining waste: This refers to any material left over after extracting minerals from ore. It includes both solid waste (such as rocks and tailings) and liquid waste (such as wastewater from processing plants).
Tailings:Tailings are a type of mining waste that consist of finely ground rock particles, chemicals, and water. They are typically stored in large ponds or impoundments after being separated from valuable minerals during ore processing.
Overburden:Overburden refers to the layer(s) of soil, rock, vegetation, or other materials that lie above a mineral deposit. It must be removed during strip mining operations before accessing the desired minerals.
