Siderite
Siderite is a mineral that is composed of iron, carbon, and oxygen. It is typically found in sedimentary rocks such as limestone and shale, and is often associated with other minerals such as quartz and calcite.
Siderite can range in color from yellow to brown to grey, and has a dull to glassy luster. It is sometimes used as an iron ore, as it contains a relatively high percentage of iron, and is also used as a pigment in paint and ceramics.

Information about Siderite
Appearance
Siderite is primarily used as an iron ore, but carbonate iron ore is definitely not as useful as typical ores like haematite, as further processing is required.
Uses and History
Siderite is primarily used as an iron ore, but carbonate iron ore is definitely not as useful as typical ores like haematite, as further processing is required.
In rare cases, siderite is faceted for jewellery usage.
These ores were, for a time, very useful as the Bessemer process for manufacturing steel required an ore with minimal phosphorus, which siderite was.
Siderite does also produce siderite concretions, which have been known to preserve some very good quality fossils.

Hazards and Warnings
Mineral collectors should wash their hands after handling specimens, to avoid any exposure to potential toxins.
Almost all rocks, minerals (and, frankly, almost all other substances on earth) can produce toxic dust when cutting, which can cause serious respiratory conditions including silicosis.
When cutting or polishing rocks, minerals, shells, etc, all work should be done wet to minimise the dust, and a suitable respirator or extraction system should be used.
