Banded Iron Formations Encyclopedia

Banded iron formations. Banded iron formations (BIFs) are chemically precipitated sedimentary rocks.They are composed of alternating thin (millimeter to centimeter scale) red, yellow, or cream colored layers of chert or jasper and black to dark gray iron oxides (predominantly magnetite and hematite), and/or iron carbonate (siderite) layers. Banded iron formations

Siderite

Siderite is a mineral composed of iron(II) carbonate (FeCO 3).It takes its name from the Greek word sideros, iron. It is a valuable iron mineral, since it is 48% iron and contains no sulfur or phosphorus. Zinc, magnesium and manganese commonly substitute for the iron resulting in the siderite smithsonite, siderite magnesite and siderite

Ore mining Britannica

Ore Ore, a natural aggregation of one or more minerals that can be mined, processed, and sold at a profit. An older definition restricted usage of the word ore to metallic mineral deposits, but the term has expanded in some instances to include nonmetallics. Although more than 2,800 mineral species

A Review on Novel Techniques for Chalcopyrite Ore

Chalcopyrite ores are usually processed by means of hydrometallurgical or pyrometallurgical processes, but due to environmental aspects and the possibility of increased exploitation of mixed and lower grade ores and relatively small isolated deposits, there has been a worldwide upsurge of interest in the hydrometallurgical

Magnesite is a magnesium carbonate mineral occurring

Magnesite is mostly an evaporite mineral found in sedimentary rocks. It also occurs as veins in ultramafic rocks, such as serpentinite and other magnesium rich rock types found in mountain forming belts. It is used in furnaces in conjunction with lime as a slag former in steelmaking. The use of magnesite protects the magnesium oxide lining. It is also

Banded Iron Formation (also known as BIF, or as taconite in North America) is a term that is applied to a very unique sedimentary rock of biochemical origin. These rocks are unique in their make up, unique in their age and unique in their origins. They are found all over the world, but only in certain areas of all the major continents.

In the bauxite refining process, the aluminum bearing minerals in bauxite are converted in a multiple step process to alumina (Al2O3). Alumina can be smelted to form metallic aluminum or it can be used as the source of many other products, including refractory materials used to line high temperature rotary kilns and metallurgical furnaces.

Iron ore

The Lower grade sources of iron ore generally require beneficiation, using techniques like crushing, milling, gravity or heavy media separation, screening, and silica froth flotation to improve the concentration of the ore and remove impurities. The results, high quality fine ore powders, are known as fines.. Magnetite. Magnetite is magnetic, and hence easily
