<p>The invention provides a process for the preparation of high purity bone mineral wherein the organic matter in degreased bone is degraded and solubilised by heating with ammonia or a primary amine, characterised in that the solubilised degradation products are extracted by washing with flowing water at temperatures below 60°C, such heating with primary amine and washing steps optionally being repeated, whereby substantially all organic matter removable by these steps is removed, the bone mineral so treated being heated in air at temperatures between 250°C and 600°C.</p> |
