Process for producing potash fertilizer from potassium feldspar
Thread Content
Dear sea friends, has anyone used potash feldspar to produce potassium fertilizers or potassium-containing compound fertilizers? Does anyone who knows about this area please share some information?
Sulfuric acid as a solvent and hydrofluoric acid as a catalyst can decompose at temperatures below 100 degrees, but the price of HF is 10,000 per ton. No one will do it at this price. When Canada and Russia also run out of soluble potassium fertilizers, they might consider adopting this process. In short, cement plants may be able to make comprehensive use of potash feldspar as well. The other kids, give up.
Could you give some details? Our company has also been granted mining rights for a potash feldspar deposit!
It’s okay; adding additives can lower the decomposition temperature, allowing for the direct production of ammonium-potassium fertilizer, and aluminum can also be extracted – so there seems to be potential for further development
Consider using fluorosilicic acid as a substitute for hydrofluoric acid
