Siderite is a mineral composed of iron carbonate FeCO takes its name from the Greek word sideros iron It is a valuable iron mineral since it is 48% iron and contains no sulfur or magnesium and manganese commonly substitute for the Its crystals belong to the hexagonal system and are rhombohedral in shape typically with curved and striated faces

We show that siderite can form via heated transformation at temperature 100°C for 48 hr of calcite and monohydrocalcite seeds in the presence of dissolved iron Our transformation experiments suggest that the formation of siderite is promoted when carbonate seeds are present 1 INTRODUCTION
