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. |
