Siderite Wikipedia
Siderite is a mineral composed of iron(II) carbonate (FeCO 3).It takes its name from the Greek word σίδηρος 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-rhodochrosite solid solution series.

Kinetics of thermal decomposition of siderite: effect of
Sep 01, 1992 On calcination, the grain of siderite becomes porous and hence becomes a good candidate of hydrogen by the steam-iron process and probably for SO2 pollution abatement (Chatterjee et al., 1980, Dhupe et al., 1989). In the recent work on intrinsic kinetics of Indian siderite from Kutch, Dhupe and Gokarn (1990) used very fine particles.

Iron ore deposits of india SlideShare
Oct 22, 2017 Origin and classification of Iron ore deposits: The iron ore deposits of India can be broadly divided in to the following six groups on the basis of mode of occurrence and origin: o Banded Iron Formation of Pre-Cambrian Age o Sedimentary iron ore deposits of siderite and limonitic composition o Laterite ores derived from the sub-aerial

Siderite an overview ScienceDirect Topics
Like the precipitation of secondary Al(OH) 3, that of secondary siderite [FeCO 3] is widely employed in geochemical models. Secondary siderite and associated iron oxyhydroxides were determined to have formed as coatings, up to 1,000 μm thick, on ankerite-dolomite in the Kidd Creek tailings impoundment at Timmins, Ontario, Canada (Al et al., 2000).

Siderite: The mineral Siderite information and pictures
Siderite is a common mineral and is found worldwide in many different environments. Only the most noteworthy will be mentioned here. Classic Siderite occurrences in Europe include Neudorf in the Harz Mountains, Germany; and Panasqueira, Portugal. Excellent gemmy greenish crystals come from Isere, (especially at Allevard), France.

India's three step nuclear program: Step 1: P.H.W.R use uranium + D2O to get plutonium + energy Step 2: Fast Breedor Reactors use plutonium + uranium oxide to get U-233 + energy Step 3: Thorium based reactors use Thorium+U-233 to get energy . BARC processes used fuel in P.H.W.R to get reactor grade plutonium for fast breedor reactors.
