Siderite Mineral Properties, Photos and Occurence

2018-11-22  Blast furnaces were serially modified with acid, then basic liners; heating times were extended; additives were reformulated to replace lost elements and ore sources were changed. All of these interventions permitted the cyclical production of steel from siderite, but over time the strength of the siderite mining sector declined.

The use of siderites in blast furnaces operated on

These advantages, combined with the favorable composition of the country rock-which has a basicity (based on CaO + MgO/SiO 2) of up to 2.6-makes it possible to classify these siderites as iron-fluxes that can be used effectively in a blast furnace. Roasted siderite concentrate (RSC) can be used efficiently in the blast-furnace charge to make different grades of manganese-bearing foundry iron as long as
