Potash rock refers to potash rock, which generally consists of more than 15% potassium salt and more than 20% rock salt, accompanied by anhydrite, clay and other admixtures. Usually, it is a natural potassium-bearing sedimentary mineral, which consists of alternating layers of KCl and NaCl. After crushing, it can be directly used as potash fertilizer, especially for sugar beet and lawn. Potash ore can also be made into fertilizer-grade potash fertilizer by dissolution and flotation.
China is a typical potassium-deficient country, and the proven reserves of potassium resources only account for about 2% of the world's reserves. In addition, there is a shortage of solid potassium ore in China, and potassium resources are mainly potassium-bearing brine, mainly concentrated in Qaidam Basin in Qinghai and Lop Nur Salt Lake area in Xinjiang. According to official website and China of China Geological Survey of the Ministry of Natural Resources, 65.438+84 million tons of liquid potassium chloride have been found in 100 million tons of extra-large potassium ore, including the extra-large potassium ore field in Lop Nur Salt Lake.
Discovery of potash deposits
It is the result of the exploration project of potassium-bearing rock in Huadian fishing village, Ji 'an City, Jilin Province, which is undertaken and implemented by the Fourth Geological Survey of Jilin Provincial Bureau of Geology and Mineral Exploration and Development. The exploration right of this mining area was first obtained in 20 10, and the geological exploration of the project has gone through 10 years. During this period, the Fourth Geological Survey of Jilin Province made a comprehensive study by studying the previous data, collecting and sorting out the data, and boldly put forward a new prospecting direction.
In the middle of the project, geologists solved the related technical problems scientifically and reasonably, and broke through the technical problems one by one, technical problems and bottlenecks. Finally, through more than two years of field geological work, they submitted a report on the exploration of potassium-bearing rock deposits in Huadian Town, Ji 'an City, Jilin Province, and passed the examination. On June 7, 2023, the mineral resources reserves of this project were reviewed and put on record.
