Background

Siderite (siderite) is a relatively widely distributed mineral whose constituent is ferrous carbonate. Siderite is typically present in thin layers along with shale, clay or coal. Siderite is generally in the form of crystal grains or compact blocks, spheres or gels without crystals. Siderite can also become limonite in the case of oxidative hydrolysis. Limonite is usually in the form of block, soil, milky or grape, loose porous or powder. Yellow brown or dark brown. The streaks were tan. The luster is dull, the hardness is different according to the components and the forms, and the hardness of the compact block rich in silicon can reach 5.5; while those rich in muddy soil have a hardness reduced to 1. Iron-containing minerals are formed through oxidation and decomposition, particularly the surface part of a metal sulfide deposit, and after the iron is oxidized, limonite is often formed and can be used as a mineral raw material for iron making.

At present, siderite processing equipment for siderite pretreatment has the defects of insufficient and imperfect treatment and the like. If siderite is not oxidized and hydrolyzed, the hardness of siderite is very low, and siderite is gelatinous and cannot be processed at all. Although some devices can complete the oxidation hydrolysis treatment of siderite, the reaction is generally insufficient, the generation is not thorough, the purity and the quality of the obtained limonite are poor, and the thorough and efficient oxidation hydrolysis of siderite cannot be realized.
