METHOD OF PRODUCTION OF KALIUM SULPHATE |
| abstract |
A process for the production of potassium sulphate using ammonium sulphate and potassium chloride, with precipitation and no evaporation. The process involves several stages of precipitation and solid / liquid separation. In the first stages of the reaction, a double salt is formed, which in subsequent steps is converted into potassium sulfate.ŕ |
