used for making iron. The presence of pyrite and pyrrhotite in sulphide ores is undesirable and usually methods have to be found to remove them [2]. Ilmenite is a source of titanium as well as iron. Although titanium minerals are used for producing titanium metal, yet 99% of the tonnage is used for TiO 2 pigment manufacture. Furthermore,
Iron ore is the raw material used to make pig iron, which is one of the main raw materials to make steel. Raw iron is alloyed with a variety of elements (such as tungsten, manganese, nickel, vanadium, chromium) to strengthen and harden it, making useful steel for construction, automobiles, and other forms of transportation such as trucks, trains and train tracks.
Bhupinder Dhir, in BioGeotechnologies for Mine Site Rehabilitation, 2018. Abstract. Acid mine drainage (AMD), a waste from mining sites is highly acidic, rich source of sulfate and heavy metals. Conventional technologies for treatment of AMD include various physicochemical methods, which involve excessive use of chemicals and capital.
Heavy metals are naturally occurring elements that have a high atomic weight and a density at least 5 times greater than that of water. Their multiple industrial, domestic, agricultural, medical and technological appliions have led to their wide distribution in the environment; raising concerns over their potential effects on human health and the environment.
Mining water use is water used for the extraction of minerals that may be in the form of solids, such as coal, iron, sand, and gravel; liquids, such as crude petroleum; and gases, such as natural gas. The egory includes quarrying, milling of mined materials, injection of water for secondary oil recovery or for unconventional oil and gas ...

· Toxic chemicals used to extract the valuable materials from the ore, such as the cyanide used in gold mining, remain in the tailings at the end of the process, and may leach out into ground water. Rock may naturally contain dangerous chemicals, such as arsenic and mercury, which leach into water much more readily after rock has been ground up and exposed to the wind and the rain.
