Process Development for Solid Fuel Use at Siderite Ore ...

The evaluation results allowed development of a roasting process for siderite ore in neutral (low reducing) atmosphere and designing of a shaft furnace operating on solid fuel. Such roasting process is of a certain interest, as far as saving the insufficient fuel types, and predominantly natural gas, is concerned. Access through your institution.

Research on Siderite Ore Reducing Firing Scientific.Net

It was determined that the current method of the Bakalsk mining department siderite ore preparation for blast-furnace smelting does not allow production of concentrate meeting the state-of-the-art metallurgy requirements. The most perspective method is reducing firing when a metallized product with higher iron content is obtained. It was demonstrated that implementation of this method requires ...

Green magnetization roasting technology for refractory ...

2019-1-1  The siderite resource is abundant in China with a reserve of approximately 1.8 billion tons. In addition, most of the refractory iron ores in China contain a certain amount of siderite. However, extensive research has reported that siderite is a refractory iron ore, which is difficult to utilize in the traditional beneficiation process.
