ferrous carbonate

The brine also contained ferrous carbonate which was held in the solution by carbon dioxide.

Iron from ferrous sulphate, for example, is more available to the horse than the iron in ferrous carbonate.

The potassium ferricyanide component is very sensitive, and will detect iron in calcite with 1% ferrous carbonate in solid solution.

Iron ore is predominately made up of ferrous carbonate and when heated forms iron oxide, and without the presence of carbon nothing further would happen.

In addition, large amounts of white siderite (ferrous carbonate) and iron sulfides (usually amorphous) were found in the cross section of the corrosion nodules.

While most standard oxygen scavengers contain ferrous carbonate and a metal halide catalyst, there are several non-ferrous variants, such as ascorbate, sodium hydrogen carbonate, citrus and others available.

Typical reasons to use a non-ferrous variant would include the packaging of products intended for international shipping where metal detection would pose a problem; a desire to reduce the odor associated with ferrous carbonate; or dietary products where contact with iron should be avoided.
