Biometallurgical technology, that is, soaking the ore with the bacterial liquid containing bacteria, these bacteria feed on the ore and obtain energy through oxidation, and because the ore is oxidized, it changes from insoluble in water to soluble, so people can extract from the solution It has the characteristics of low cost, low pollution, and reusability. Compared with the high cost and high pollution of conventional metallurgical technology, biometallurgy has a more obvious advantage in processing low-grade minerals, which is also one of the ideal directions for the future development of the metallurgical industry. Bacteria commonly used in biometallurgy include Thiobacillus ferrooxidans and Thiobacillus thiooxidans. They are two autotrophic microorganisms that can obtain energy by oxidizing ferrous sulfate or reducing sulfide. In the oxidation process, many reducing sulfur compounds can be produced, and these compounds are further oxidized to sulfates through chemical action or the action of Thiobacillus, and sulfuric acid is generated under certain conditions). Ion chromatography analysis is used to monitor the morphological changes of sulfur in the biological leachate system, which helps to grasp the role of bacteria in the entire smelting process.
In this summer of barbecue carnival, sitting around with friends, setting up a grill in the middle, putting a big pile of skewers on it, brushing with oil, sprinkling with seasonings, the smell of barbecue straight to the nose, you should have an outdoor barbecue!
But organize an outdoor barbecue, the preparation of tools is very troublesome?
