Siderite an overview ScienceDirect Topics

Siderite is paramagnetic at ordinary temperatures and carries no NRM. Its interest is as a source of diagenetic magnetite. On Earth, the oxidation of siderite at room temperature and accompanying CRM acquisition is well documented (Hus, 1990). The process becomes rapid and even explosive at higher temperatures, and the magnetite CRM effectively

Upgrading of Iron Concentrate by Fluidized-Bed

2019-3-6  Efficient use of abundant low-grade siderite ores can potentially mitigate the shortage of iron ore in the iron and steel industry in China. In this work, the beneficiation of siderite fines containing high levels of carbonates was studied using a combined fluidized-bed magnetizing roasting process. The siderite was almost completely converted into magnetite under the optimum conditions of

Processes and Procedures in the Extraction of Iron

2021-2-15  The extraction of iron from its ores is quite a technical process. The iron ore is first roasted in air to produce iron(III) oxide which is mixed with coke and limestone and then further heated to a very high temperature in a blast furnace. These materials are loaded into the blast furnace from the top while a blast of hot air is introduced into it from beneath via small pipes known as tuyeres.
