The invention relates to a method that includes: placing a bone material, containing hydroxyapatite and organic substances, in contact with an extraction liquid that gives rise to a first liquid phase, containing said organic substances and possibly impurities extracted from said bone material, and a second solid hydroxyapatite phase, containing said hydroxyapatite; and separating said liquid phase and said solid hydroxyapatite phase. Said extraction liquid is an aqueous extraction solution brought to a temperature between 150° C. and 300° C. and a pressure between 150 kPa and 350 kPa. |
