Synthesis of magnetite powder from the mixture consisting of siderite
The formation of magnetite started at 400 °C, resulting in magnetization increase. Both siderite and hematite transformed into magnetite, since two different Curie temperatures were recorded at cooling. The mixture consisting of siderite and hematite ores in equal proportion completely transformed into magnetite.
