Dec 19, 2018· This stone is named Phosphosiderite because of its mineral makeup. It contains phosphorous, phospho, and iron, siderite. The word siderite is from the Greek word sideros, which means iron. It's also sometimes called 'PiedreaVoga', which means pink stone, and 'La Rosa Voca', which means pink rock. It exhibits a purple to reddish violet color.
Siderite mineral process plant and siderite processing method. Siderite instruction Siderite processing method.

Siderite is one of the significant iron ore resources in China and yet is difficult to upgrade by traditional beneficiation processes. A process of coalbased direct reductionmagnetic separation was successfully developed for the beneficiation of siderite.
Lowpermeability corrosion products (, siderite, as formed in the presence of certain oils and/or inhibitors) Nature of steels. Alloying iron with carbon (usually to 1%) forms steel (lowalloy steel)—a far stronger metal than iron, hence, suitable for oilfield use.

Siderite is usually not found as pure FeCO, in nature; Both Mn'z* and Mg2* can substitute for Fe2* in appreciable amounts. A complete solidsolution series exists between siderite and magnesite, and between siderite and rhodochrosite (Deer et al., 1962). This paper investigates the former series. Mineral carbonates containing Fe and Mg have been

Isothermal experiments were conducted to investigate the thermal decomposition kinetics of siderite lump in a weakly oxidising atmosphere at 500–850°C. The results reveal that siderite has selfmagnetisation characteristics under controlled conditions, and the phase evolution process and final products of decomposition depend temperature and atmosphere.
