siderite uses


Description: Siderite forms as a sedimentary precipitate, in hydrothermal veins, in metamorphic rocks formed from such protoliths, and, rarely, in pegmatites. In sedimentary environments it forms in extensive beds of banded iron formations and as more localized deposits of bog-iron ore. It readily weathers to iron oxides.

Siderite forms mostly in sedimentary and hydrothermal environments, although it is also found in some igneous pegmatites. Siderite is a common mineral although excellent, attractive crystal specimens are sometimes hard to find. But many crystals, when colorfully iridescent, make a wonderful, colorful, satiny, shimmering mineral specimen.

Roasted siderite concentrate (RSC) can be used efficiently in the blast-furnace charge to make different grades of manganese-bearing foundry iron as long as unfluxed pellets are also employed. On the average, the addition of 10 kg of RSC to the charge per ton of pig iron reduces the consumption of dry skip coke by 0.6-1.5 kg/ton pig and ...

To be suitable for cutting faceted gems cassiterite must be transparent, free of fractures, be of high clarity and have an attractive color. When cut properly, cassiterite can be a beautiful gemstone. It is known to occur in brown, yellow, orange, red and green. Some stones have a strong fire that rivals the fire of diamond. [1]

2.2. Methods. The natural siderite (FeCO 3) used as a reductant in the magnetization roasting process was mainly attributed to the carbon monoxide (CO) that occurred in the thermal decomposition process.Much research has been conducted on the thermal stability of siderite, and the two-step decomposition mechanism in a neutral atmosphere has been commonly accepted (Chang and Ahmad, 1982).

Siderite is a mineral composed of iron 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.Both magnesium and manganese commonly substitute for the iron.. Its crystals belong to the hexagonal system, and are rhombohedral in shape, typically with curved and striated faces.

Siderite is a type of mineral that is composed of iron (II) carbonate (FeCO 3 ). Its name comes from the Greek term "sideros" which means iron. It is an essential iron mineral, as it is composed of 48% iron without phosphorus or sulfur. This mineral is classified as calcite which is a cluster of carbonates that are all considered isomorphous.
