Toxic chemicals used in mining include: cyanide, sulfuric acid, and solvents for separating minerals from ore; nitric acid; ammonium nitrate and fuel oil (“ANFO”) used in blasting tunnels
The chromium extracted from chromite is used in chrome plating and alloying for production of corrosion resistant superalloys, nichrome, and stainless steel. Chromium is used as a pigment for glass, glazes, and paint, and as an oxidizing agent for tanning leather. It is also sometimes used as a gemstone. Porcelain tile pigmentation
Chromite is the main source of the metal chromium, a metal used to induce hardness, toughness and chemical resistance in steel. It was named after its chemical composition, chromium oxide. The mineral is brownish to black in colour with a dark brown streak. ... Chrome mining in Canada (The Ring of Fire):
Chromium (Cr) is a versatile element used in numerous applications in the metallurgical, chemical, foundry sand, and refractory industries. Chromite (FeCr 2 O 4) is the only commercially recoverable source of Cr.South Africa holds approximately three-quarters of the world's viable chromite reserves.

Apr 07, 2015· Chemical Used in Gold Mining - Refractory Gold Ores The gold also occurs as sub microscopic particles in sulphides or as absorbed gold onto surfaces of carbonaceous matter. Because of the variation of these refractory ores, gold occurrence is ore specific and before process decisions are made, competent mineralogical and metallurgical ...
Chrome ore is usually for production of ferrochromium and chrome, which is widely used in metallurgical industry, refractory matter, chemical industry and so on.
The earliest form of marine mining entailed shore diving, where a swimmer would collect diamond bearing gravel from the shallow seabed. Today technology has evolved to specialised ships that mine for diamonds deep out at sea. These specialised ships use a powerful crawler that sucks gravel on the seabed up through flexible hoses/pipes.
Chromium (Cr) has a wide range of uses in metals, chemicals, and refractories. It is one of the Nation's most important strategic and critical materials. Chromium use in iron, steel, and nonferrous alloys enhances hardenability and resistance to corrosion and oxidation. The use of chromium to produce stainless steel and nonferrous alloys are two of its more important

Water, streams and rivers are the main drivers in the formation of secondary mining deposits as they can transport rough diamonds away from Kimberlite pipes to locations as far out as the ocean. Another mining method that is frequently used is called alluvial mining.
Chromium is unstable in oxygen, it immediately produces a thin oxide layer that is impermeable to oxygen and protects the metal below. Applications. Chromium main uses are in alloys such as stainless steel, in chrome plating and in metal ceramics. Chromium plating was once widely used to give steel a polished silvery mirror coating.
