siderite and pyrite

Millerite, NiS, has been identified for the first time in cinnabar- and pyrite-bearing siderite ore samples from „Steirischer Erzberg", Styria, Austria. In addition, the occurrence of other nickel sulfides has been confirmed, such as siegenite-violarite solid-solutions 2 S A carbonate concretion from the shale bed overlying the No. 5 coal of Pennsylvanian age in Tuscarawas County is composed of siderite and contains pyrite, barite, sphalerite and traces of calcite in its interior and in fractures. The siderite has 8I 3C= +0.65%o, Sr

2017/5/28The physical and mechanical properties of pellets which were obtained using the raw siderite and the calcined siderite were compared with each other. As a result of experimental studies, it was found that the calcination process decreased the milling time, causing the significant energy saving and the most suitable calcination process for siderite ore was found as 15 min at 700C temperature.

SIDERITE (Iron Carbonate)

Siderite is named for the Greek word for iron, sideros.The word siderite is used in a number of rarer minerals and except in the fact that they all contain iron, they are otherwise unrelated to siderite. They include: Alumopharmacosiderite, arseniosiderite, barium-alumopharmacosiderite, barium-pharmacosiderite, chalcosiderite, erythrosiderite, pharmacosiderite, phosphosiderite and
