On February 23, the Qinghai Provincial Department of Science and Technology organized relevant experts to jointly undertake the “Qinghai CITIC Guoan Lianyu Potash Fertilizer Co., Ltd. with an annual output of 150,000 tons of potassium magnesium magnesium "Technical transformation and optimization of fertilizer technology" technology personnel service enterprise action plan project was checked and accepted and the results identified. The project relies on the patented technology of the Qinghai Salt Lake Research Institute to use potassium-containing sulfate ore to prepare potassium and magnesium sulfate fertilizers. It uses room temperature decomposition and conversion and flotation separation technologies to transform the original heating conversion and sieve removal of sodium to produce potassium and magnesium sulfate fertilizers. The technological process is better optimized, and the design and production capacity of potassium sulfate and magnesium fertilizer is realized. After the production and operation evaluation, the potassium sulfate magnesium fertilizer flotation agent has strong adaptability, good selectivity, and high yield. The pharmaceutical system is reasonable. The potassium yield has increased from 30-35% of the original process to 66-68% now. Energy consumption Decreased by 40%, water consumption reduced by 45-55%. The production cost per ton of products has been reduced by more than 300 yuan, and the product quality has reached the national standard GB / T20937-2007. After reporting, questioning and answering questions, the expert group unanimously agreed that the project passed the acceptance and evaluated the results, and considered that the results reached the domestic leading level.
