About this site

Jan 25, 2005  Table 1 details the concentrations of iron removed by the different extraction techniques for a range of Fe minerals. The data shown relate to the optimum extraction times determined for each technique. Tests of the effectiveness of various acetate extractions for the dissolution of crystalline siderite were complicated by the fact that natural siderite rarely occurs in pure form.

Jan 15, 2009  The influence of time extraction from 0.5 to 8 h for HAc of concentrations of 0.1 and 0.25 mol L −1 on iron concentration was rather insignificant. The mean iron concentration equaled 0.67 ± 0.03% (m/m) for these extraction conditions. This quantity of iron resulted from the presence of this element in dissolved calcite.

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.
