An experimental study of the system CaCO3–MgCO3–FeCO3 was undertaken in order to calibrate the iron correction to the calcite–dolomite geothermometer, which is based on the solubility of magnesium in calcite in the assemblage calcite + dolomite. The experiments, at 450°C and lower temperatures, resulted in products with a very small grain size and …

Word Equation. Hematite + Carbon = Iron + Carbon Dioxide. Fe2O3 + C = Fe + CO2 is a Single Displacement (Substitution) reaction where two moles of Hematite [Fe 2 O 3] and three moles of Carbon [C] react to form four moles of Iron [Fe] and three moles of Carbon Dioxide [CO 2]
Ore is a deposit of one or more precious minerals in the Earth's crust. The most important ore deposits, such as copper, silver, and iron, contain metals that are essential to industry and trade. Copper ore is mined for a wide range of industrial applications. Copper, an exceptional electricity conductor, is used as an electrical wire.
ABSTRACT Siderite ore (FeCO3) is an important iron ore resource that is widely distributed around the world. However, it is difficult to process using conventional methods owing to the low iron grade, easy sliming, and high impurity content. Based on the mechanism of thermal decomposition, the combination of metallurgy and processing is a promising method to …

Siderite occurs as clay ironstone, an impure mixture of siderite with clay minerals. It may form concretions or concentric layers. It may also occur as black-band ore, which can form extensive stratified beds admixed with shales, other carbonates, and coal. Siderite is also formed as iron rich waters replace Ca in limestone.
