APPARATUS FOR BIOCHEMICALLY LEACHING ORES Russian patent published in 1994 - IPC

Abstract RU 2011691 C1

FIELD: chemical engineering. SUBSTANCE: apparatus incorporates percolator and solution bacterial recovery apparatus integrated into closed circuit by solution circulation system. Solution bacterial recovery apparatus is composed of fermenter and systems for automatically maintaining prescribed temperature and oxygen content, feeding solution to percolator and monitoring and recording oxidation-reduction potential, pH value and rotational speed developed by stirrer. Taken together, these systems allow controlling bacterial leaching process and intensifying it. EFFECT: more intensive process. 1 dwg
