Abstract

The invention provides a bacterial agitation leaching experimental facility and a method for measuring and calculating oxygen mass transfer coefficients, bacterial oxygen consumption rate and saturated dissolved oxygen concentration. The experimental facility is suitable for bacterial agitation leaching in particular for the bacterial leaching at a high temperature, can provide online regulation control and measurement of temperature, pH, ORP and DO, and simultaneously has a real-time recording function. In the invention, a dynamic method in a fermentation technical research is used for measuring and calculating the oxygen mass transfer coefficients, the bacterial oxygen consumption rate and the saturated dissolved oxygen concentration. The bacterial agitation leaching experimental facility has the advantages of not only providing a bacterial agitation leaching device capable of performing online regulation control and recording correlation parameters, but also being suitable for researching the oxygen supply and consumption in the process of high temperature bacterial agitation leach, thereby providing a strong support for rate-limiting factors of high temperature bacterial leaching.

Description

technical field

[0001] The invention relates to a bacterial stirring leaching experimental device and its method for measuring the oxygen mass transfer coefficient, in particular to the experimental device for stirring and leaching chalcopyrite concentrate with thermophilic bacteria and the method for measuring the oxygen mass transfer coefficient and the bacterial oxygen consumption rate. And the determination of saturated dissolved oxygen concentration. Background technique

[0002] When studying bacterial growth and ore leaching characteristics in the field of biometallurgy, the shake flask experiment is generally started. This experiment is simple to operate, easy to control, and has good stability, but the disadvantage is that it cannot be controlled and measured online. Bacterial leaching of chalcopyrite has always been a difficult problem. There will be obvious passivation phenomenon when leaching with normal temperature bacteria or mesophilic bacteria, which will aff...
