After heavy firing, siderite and ankerite becomes magnetic, dolomite and calcite does not. If a carbonatic sample is wetted with a weak acid solution of K 3 Fe(CN) 6 , some carbonates gets a blue color (Turnbulls blue) : calcite none, dolomite none, ankerite light blue, siderite dark blue.
They are similar in many physical properties, and may partially or fully replace one another, forming a solid solution series. All members of the calcite group crystallize in the trigonal system, and have perfect rhombohedral cleavage. Siderite is easily altered to iron oxides. A brown Goethite replacement of Siderite is common. Limonite, an amorphous mineral

technical information Siderite Iron Carbonate Siderite is a mineral composed of iron carbonate FeCO3. 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. Both magnesium and manganese commonly substitute for the iron.

Siderite is a carbonate mineral (FeCO 3). It is not rare but nowhere as common carbonate as calcite (CaCO 3) and dolomite (CaMg(CO 3) 2). Typically to carbonates, siderite also forms rhombohedral crystals. It shares the same crystal structure with calcite, but there is no solid solution between them because Ca and Fe ions are significantly ...

Dissolving siderite is actually hard. Water won't do it. You need to use an acid, and high temperatures. There are papers by the Rosenheim group and ETH that shows that you need to use acid at 100˚C over a period of more than an hour to obtain complete dissolution of the siderite.
