The present invention relates to a process for the treatment of beeswax from beekeeping farms, contaminated with residues of veterinary and phytosanitary treatments by means of a process of extraction of the molten wax with methanol and the subsequent steps for the adaptation of the wax obtained to manufacture hives therefrom that are accepted by the bees, and that can also be used in galenic formulations. Therefore, the technological framework in which this invention is included is that of beekeeping and, more specifically, beeswax extraction processes and devices.
