release of impurities from a calcium based mineral |
| abstract |
A method for releasing impurities from a calcium-based mineral is described. The method comprises reacting a calcium-based mineral containing impurities with an aqueous solution of one or more ionic salts at a temperature of approximately 85 ° C or more, wherein at least one of the calcium-based mineral and the one or more salts. The ionic salts comprise sulfate and at least one of the calcium-based mineral and the one or more ionic salts comprise ammonium and wherein the concentration of the solution is approximately 25% or more by mass so that double salt crystals are formed. and the impurities are released. The method further comprises separating the double salt crystals from the impurities. Several process products are also described. |
