The raw material is digested with a digestion liquor (L) of an aqueous solution of sulphuric acid (H2SO4) and a mineral acids (HX), in a ratio (H+(SA)/H+(L) of between 2 and 75%, where H+(SA) and H+(L) are the mole content of H+issued from the sulphuric acid and the digestion liquor (L), respectively. The in amounts such that the molar ratio H+(L)/Ca is between 0.8 and 1.95, wherein Ca is the mole content of calcium. The digested suspension is separated into an aqueous phosphate rich solution and a first solid phase.
