The main marketable product, potassium sulphate (SOP), is a completely harmless potash fertilizer of the highest quality. According to the technology, a chemically pure product is produced, because initially there is no chlorine content in the raw material, what compares favorably with existing technologies for obtaining SOP. Potash fertilizers have an extremely beneficial effect on the development of most crops, potatoes, beets, grapes, citrus fruits, sunflowers, and many others. Globally, the main raw materials for potash fertilizers are sylvins (potassium and chlorine compounds) and it is expensive and time-consuming to completely get rid of the presence of chlorine, which accelerates the processes of decay. As a result, chlorine compounds significantly reduce the safety of harvested agricultural products. By processing synnyrites, we get a product free from the main disadvantage, expanding the range of potassium sulfate application. Even a small amount of potassium sulfate – 100-150 grams, can serve as a vital source for one hundred square meters of agricultural land. Continuous growth of the Earth’s population stimulates the optimization and development of agriculture, the cultivation of new crops, increasing their productivity, what creates a natural demand for mineral fertilizers.
Alumina obtained from synnyrites along with potash fertilizers is a raw material for the production of aluminum. Currently, this metal is in demand and indispensable for solving a whole range of problems in engineering, metallurgy, everyday life, food industry, etc. For example, over the past 20 years, primary aluminum production in China has increased over twenty-fold, and its consumption is growing in a similar way. In connection with the growing consumption of aluminum, the issue of finding new deposits and developing new extraction technologies is relevant.
Obtaining alumina during the integrated processing of synnyrites at the Kalyumnoe subsurface site allows to organize a unique waste-free production.
The volume of the synnyrite deposits of the Kalyumnoe subsurface site is enormous, and can provide enterprises of Russia and the world with raw materials for the potash fertilizers and alumina production for many years.
