Iron PTMS MAGNETIC SEPARATOR iron removal method by zinc hot acid in the presence of alkali metal, the solution close to the boiling temperature, then into iron crystal (mFe (SO4) 2 (OH) 6, formula m represents the monovalent ion, such as K, Na, Rb, Cs, Li, Ag, NH ₄, H ₃ O) precipitation, in order to remove iron as far as possible, in the reaction process need to add neutralizing agent to maintain pH value at around 1.5,
At the same time, the reaction temperature needs to be maintained at a higher temperature close to the boiling point of the solution, and this method will consume a lot of reagents and energy.
Needethore PTMS MAGNETIC SEPARATOR iron removal: iron is mainly precipitated from the solution in α -FeOOH and β -FeOOH, the process can be carried out at atmospheric pressure, the temperature is maintained in the range of 70-100℃,
Needethite forms large crystals, with less valuable metals, which is easy to filter. If the process of converting Fe² into Fe³ during reaction PTMS MAGNETIC SEPARATOR is slow, the processing time is long (basically more than 24h), and there are more anode ions in the sediment, which reduces the value of iron slag as a by-product.
