Simultaneously Roasting and Magnetic Separation to Treat Low ...

During the roasting process, siderite (FeCO3) transforms to magnetite (Fe3O4) along with producing carbon monoxide (CO), but hematite (Fe2O3) needs CO to reduce into magnetite. The process of simultaneously roasting and magnetic separation was developed to treat the low grade siderite and hematite ores without...

Metallization of siderite ore in reducing roasting | SpringerLink

A difference in the mechanisms of the metallization of crude ore and the roasted concentrate is observed. The metallization of roasted concentrate lumps is more efficient than that of crude siderite ore. In this case, the process ends earlier and can be carried out at higher temperatures (1250–1300°C) without danger of skull...

State-of-The-Art-Technology in Ore Mining - Mineral Processing - Logo

The “cut-off grade”, i.e. the minimum level at which mined ore is still worth processing, is currently at 22.0 % Fe which amounts to 25 % of siderite and ankerite. Ore with a ferrous content of above 30 %, which corresponds to approximately 55 % siderite aggregate material, is called ‚finished ore' (about 1 million tons/year).

Neutralization Potential of Overburden Samples Containing Siderite

Abstract. Acid-base accounting (ABA) is a common procedure to predict the alkaline or acid-producing potential of overburdens. Neutralization potential (NP) as currently written in ABA overestimates alkalinity when siderite (FeCO3) is present in the overburden. Siderite initially yields alkalinity upon digestion, but with time...
