Limonite - Wikipedia

Limonite is relatively dense with a specific gravity varying from 2.7 to 4.3. It varies in colour from a bright lemony yellow to a drab greyish brown. The streak of limonite on an unglazed porcelain plate is always brownish, a character which distinguishes it from hematite with a red streak, or from magnetite with a black streak. The hardness is variable, but generally in the 4 - 5.5 range. Although originally defined as a single mineral, limonite is now recognized as a mixture of related hydratedcompare siderite with limonite,what are limonite and siderite ores used for what are limonite and siderite ores used for Different Types of Iron Ore Mineral Processing Siderite Siderite or spathic iron ore is usually gray or white but at the surface it weathers to limonite and the weathering may extend to a considerable depth A rusty capping may cover a deposit of siderite Where the ore forms the face of a cliff the...Siderite: The mineral Siderite information and pictures,Limonite, an amorphous mineral, is commonly found in rhombohedral crystals, as it frequently pseudomorphs after Siderite.

Zinc, magnesium and manganese commonly substitute for the iron resulting in the siderite-smithsonite, siderite-magnesite and siderite-rhodochrosite solid solution series.Decomposition of Carbon Disulfide Using Dielectric Barrier,,Siderite (FeCO3) is a traditional iron mineral resource used in steel smelting. China’s siderite resources, with reserves of 2 billion tons, are especially abundant. However, only 10% of the country’s siderite reserves have been utilized thus far (Xing et al., 2017; Huang et al., 2017).
