Embodiment Construction

[0034] The inventive reactor for the continuous production of inoculum is a bubble column reactor with a cylindrical body consisting of a cylindrical body (1) and a bottom plate (2). The reactor is closed by a cover (3) which enables the reactor to be covered and also allows substances that may fall on the reactor to slide off the reactor, preventing them from remaining on the reactor. This makes it possible to prevent foreign substances from falling into the reactor, so that the reactor can be installed in the open air, which also makes it possible to reduce the construction cost of the cover by avoiding having to support the weight of substances that may accumulate on the cover.

[0035] The materials of construction of the reactor, as well as of all components operating or used inside the reactor (e.g. coils, baffles, supports, etc.) Solutions as low as 1.0 remain in contact. Among other materials, polyester reinforced glass fibers (using phenolic or alquidic resins), and ...

Abstract

The invention publishes a reactor and method for the culture, biooxidation of cations in solution and / or large-scale propagation of jointly isolated microorganisms, with or without native microorganisms that are useful in sulfide metal ore bioleaching. The invention particularly publishes a reactor for the large-scale culture and / or propagation of an association of Acidithiobacillus thiooxidans Licanantay DSM 17318 isolated microorganisms jointly with Acidithiobacillus ferrooxidans Wenelen DSM 16786 with or without the presence of other microorganisms.

Description

technical field [0001] The present invention relates to reactors for large-scale continuous cultivation and / or propagation of microorganisms useful for metal sulphide leaching of ores, which are co-isolated with or without native microorganisms. The reactor is also used for biological oxidation through the action of extremophilic microorganisms capable of oxidizing cations such as ferrous, arsenous, cuprous or Cations contained in effluents, liquid industrial residues or other solutions of industrial value. In particular, the present invention relates to a reactor for large-scale cultivation and / or propagation of a combination of Acidithiobacillus thiooxidans Licanantay DSM 17318 isolated microorganisms together with Acidithiobacillus ferrooxidans Wenelen DSM 16786 with or without other microorganisms. Background technique [0002] In general, in the cultivation of microorganisms, artificial or specially formulated media are used, often starting from organic and / or inorgani...
