Description
Technical Field
The invention relates to a method for extracting natural minerals and trace elements from natural ores, in particular to a method for extracting natural minerals and trace elements from ores by using microorganisms.
Technical Field
It is well known that the development of modern industry brings about serious damage to ecological environment and more serious pollution to drinking water. In order to ensure the safety of drinking water, the drinking pure water is produced at the same time, and at present, the drinking pure water on the market is mainly produced by adopting a reverse osmosis technology and a distillation method. The methods can really achieve the purpose of improving the quality of drinking water, but simultaneously bring a series of problems, and because the purified water is too pure and lacks of minerals and trace elements necessary for human bodies, the minerals and the trace elements in the human bodies are unbalanced after long-term drinking, thereby causing a series of diseases. In order to solve the problem, many pure water plants begin to add artificially synthesized inorganic salts, such as potassium salt, sodium salt, calcium salt, magnesium salt and the like, into pure water to prepare mineral water, and because the types and the amount of the inorganic salts in the water are very small and the activity of the water cannot be improved, the artificially synthesized mineral water cannot be absorbed by human bodies, animals and plants and cannot achieve the aim of comprehensively and uniformly supplementing mineral substances and trace elements required by the human bodies, the animals and plants.
In agriculture and planting industry, in order to improve yield, a great amount of pesticides and fertilizers are used at present, and the fertilizers are mainly composed of plant skeleton elements such as nitrogen, phosphorus, potassium and the like, but other minerals and trace elements are needed for plant growth besides the skeleton elements, the essential minerals and trace elements are not needed, and the quality of crops and economic crop fruits is deteriorated. At present, people feel that fruits such as cucumbers, eggplants, tomatoes, strawberries, cherries and the like grow greatly, but the fruits are not delicious, which is the reason. In addition, a large amount of pesticides and fertilizers are used, and adverse consequences such as land hardening and soil degradation are brought. In order to solve the problem, a plurality of compound fertilizers and trace fertilizers are developed, however, most of the compound fertilizers and the trace fertilizers are artificially synthesized and lack activity, and because the activity is poor, mineral substances and trace elements in the compound fertilizers and the trace fertilizers cannot be absorbed by plants and enter the cells of the plants, so that the fertilizer efficiency is not obvious.
In the wine industry, in order to obtain a good wine, the winery must store the new wine that has just been produced in the cellar for ten or eight years, for which reason the winery must pay high investment costs and time costs.
In the aspect of tap water treatment, the tap water treatment technology in China is not greatly improved for decades, the traditional chlorination mode is still adopted for sterilization and disinfection, drinking water sources are seriously polluted along with the development of modern industry, a plurality of pollutants are contained, the pollutants cannot be treated only by the simple chlorination mode, and the pollutants form serious threats to the health of people. Therefore, the conventional tap water treatment process must be modified or upgraded.
In the aspect of beautifying, a plurality of current cosmetics, skin care products and cosmetics and a beautifying method seek sufficient nutrient components in one face, neglect the activity of the nutrient components and have no activity, and the nutrient components can not be fully absorbed, thereby causing poor skin care and beautifying effects.
Before the invention, the preparation method of the natural mineral and trace element activation concentrated solution similar to the preparation method of the natural mineral and trace element activation concentrated solution is adopted, most of the natural mineral and trace element activation concentrated solution is prepared by using a chemical method, and mineral and trace elements in ores are leached by using an acidification oxygen injection process at high temperature and high pressure. The microbial metallurgy technology is now a well established biometallurgical technology. The industrial production on a large scale is started in the seventies of the last century, the world produces copper and the Congo, millions of tons of electrolytic copper are exported every year, all the electrolytic copper is produced by utilizing the microbial metallurgy technology, and the purity reaches more than 99 percent. The microbial metallurgy technology of China starts in 1997, and the Jiangxi copper industry builds the first microbial wet copper smelting plant in the Jiangxi Dexing copper mine in China, and the annual electrolytic copper yield is 2000 tons, and the purity is 96%.
