Abstract

The invention discloses a process for processing mineral medicaments such as cinnabar, orpiment, native copper, magnetite, and reddle, especially the method for dissolving and removing hazardous materials in the medicaments, which comprises processing the minerals with bacteria, dissolving the minerals insoluble to water into aqueous solutions under the action of bacteria, then removing unwanted ions in the solution through chemical or physical methods.

Description

technical field [0001] The present invention relates to a treatment method for traditional Chinese medicine ore medicine (referring to mineral medicine in traditional Chinese medicine and other ethnic medicines), more precisely, it is a kind of treatment method for using bacteria to treat insoluble mineral medicine, such as: cinnabar, realgar, natural copper , Magnet, substitute ocher, etc., become soluble components and dissolve into the solution, and remove harmful substances. Background technique [0002] In addition to a large number of herbal medicines and animal medicines, the Pharmacopoeia of Chinese Medicine also contains many mineral medicines, such as: cinnabar, realgar, natural copper, magnet, ochre, etc. In Chinese medicine practice, the unique effects of these drugs are used to treat various diseases in combination with other drugs. However, due to the excessive amount of heavy metal harmful ingredients contained in mineral medicines, its use is subject to some...
