WO2012095815A1 - Production of calcium carbonate -

The invention relates to a process of producing precipitated calcium carbonate. The process includes, in a calcium dissolution step, contacting a solid particulate feedstock, which contains calcium as a calcium compound in a calcium-containing matrix, with hydrochloric acid. At least some of the calcium is thereby dissolved from the matrix and is recovered as an acidic calcium-containing solution.
