We take pride in our environmentally-responsible mining process when producing our flagship mineral products – iron carbonate (siderite) and iron oxide (hematite/magnetite). Established in 1962 by Mathis & Mathis Mining Co., Sidco Minerals was purchased in 1993 by the next generation of mineral processors.

The process becomes rapid and even explosive at higher temperatures, and the magnetite CRM effectively masks any remaining NRM of the carbonate rock being thermally demagnetized.

The description of the old process is included, as it is a standard method for the treatment of blende-siderite ores, the direct separation of which is not always advisable. The ore treated at Friedrichssegen was a mill product, assaying from 11 to 15 per cent. zinc (as blende) and 18 to 23 per cent. iron (as siderite).

Iron makes up 5.6% of the earth's crust. There are many minerals containing Fe, but the principal minerals including this element can be noted as hematite Fe 2 O 3, magnetite Fe 3 O 4, limonite Fe(OH) 3, siderite FeCO 3, and pyrite FeS 2 (Bolewski and Manecki, 1993).The background process leading to the presence of Fe in natural water is leaching from rock formation.
