In our work, the preparation technique of high pure manganese sulfate directly from low-grade rhodochrosite ore (MnCO 3) was studied and improved intensively, including the effective leaching process and the short purifying process
Sep 18, 2013· Manganese is a silvery-gray metal that resembles iron It is hard and very brittle, difficult to fuse, but easy to oxidize  Manganese metal and its common ions are paramagnetic  Manganese tarnishes slowly in air and oxidizes ("rusts") like iron in water containing dissolved oxygen
Manganese was used long before it was isolated as an element , 10 million tonnes of manganese ores are mined and smelted every year as pyrolusite or rhodochrosite (manganese carbonate) The main mining areas are China, South Africa and Australia , or aluminium, or by the electrolysis of manganese sulfate Manganese metal is not ,
The invention discloses a method for preparing trimanganese tetroxide by using rhodochrosite, comprising the following steps of: lixiviating the rhodochrosite by using a sulfuric acid solution to prepare a manganese sulfate solution; then purifying the manganese sulfate solution; then adding ammonia water to the purified manganese sulfate .
Manganese occurs principally as pyrolusite (MnO2), and to a lesser extent as rhodochrosite (MnCO3) More than 2 million tones are mined every year in Iran, representing 600,000 tons of the metal The main mining areas for manganese ores is in south east and north east of Iran

For example, calcite (calcium carbonate), rhodochrosite (manganese carbonate), and siderite (iron carbonate) are all different kinds of carbonat They all have the same carbon atom surrounded by three oxygen atoms, but they also have different atoms, such as manganese, iron, or calcium
