The company holds mining rights for 724.3493 km² east of the Chaka Salt Lake Railway, producing products such as “Blue Sky” potassium chloride and “Aviation” magnesium chloride, with an annual potassium chloride output exceeding 1 million tons. Zangge Potash Fertilizer is one of the drafters of the national standard for potassium chloride and a national pilot unit for green mines. Globally, the company actively integrates into the “Belt and Road” national strategy, seeking high-quality mineral resources. In 2023, it signed the “Potash Exploration Agreement for Sainyabuli and Bokeo Counties, Vientiane, Laos” with the Laotian government and has secured mining reserves covering 157.72 km² in these regions, with estimated potassium chloride resources of approximately 984 million tons. The first phase of the project is planned to have an annual capacity of 2 million tons. Through expanding resource reserves, the company significantly strengthens China’s potassium resource base, ensuring domestic supply, closing the potash gap, and safeguarding national food security.

Since its establishment, Zangge Potash Fertilizer has adhered to a technology-driven strategy, overcoming challenges in extraction technologies such as “separation of mining and transportation, dispersed brine extraction, and centralized brine transport”; salt field brine dilution and water-chain techniques; low-grade ore processing for high-quality potassium chloride; and single-stage drying with primary bag dust collection. As China’s largest potash production base, Chaka Salt Lake contains abundant low-grade solid potassium resources. The company independently developed the “solid-to-liquid” technology to activate low-grade potassium ore, ensuring long-term efficient utilization of potassium salts and the supply of strategic resources. This technology won the Third Prize of Qinghai Provincial Science and Technology Progress. By employing “separation of mining and transportation, dispersed brine extraction, and centralized brine transport,” the company achieves high brine utilization, with potassium chloride recovery rates above the industry average. The implementation of new technologies on low-grade ore is expected to extend the mine’s service life by at least 20 years. To meet higher market requirements for potassium chloride quality, the company collaborates with leading research institutions and universities to develop technologies such as “High-Quality Potassium Chloride Production via Direct Flotation Process,” “Comprehensive Utilization of Tailings and Tail Brine from 2 Million t/a KCl Co-production,” and “Process Applications for Improving Sylvite Flotation and Fine Salt Separation.” These initiatives produce large-crystal, high-quality potassium chloride products, improve product quality, and reduce production costs. At the same time, the company promotes effective, high-value utilization of magnesium resources, supporting sustainable and balanced salt lake resource development and the circular economy. To date, the company has completed 11 R&D projects, won the National Technology Market Golden Bridge Award (1), Qinghai Provincial Science and Technology Progress Awards (2), and Haixi Prefecture Science and Technology Progress Awards (2), obtaining 3 certificates of scientific and technological achievement. Independently developed technologies have led to 2 authorized invention patents, 15 utility model patents, 2 pending invention patents, and 5 pending utility model patents, all applied in frontline production.

Zangge Potash Fertilizer firmly believes that “talent is the primary resource,” establishing internal recruitment, talent development, retention mechanisms, and human resource planning. The company also reports lists of senior technical and management personnel to provincial, prefectural, and municipal talent authorities. Adhering to ecological and environmental requirements, the company advances resource efficiency and sustainable development, building a model for circular economy. Optimized technology routes and green production principles reduce environmental burdens from the source. Through processes such as brine recycling and tail brine recovery, in 2024, the company maintained a 100% comprehensive utilization rate of liquid waste, with resource extraction and recovery indicators at advanced domestic levels. In co-developed projects, bromine and iodine recovery technologies increase efficiency in extracting deep brine by using “special adsorbent iodine adsorption + oxidation adsorption for bromine,” fostering a diversified industrial chain. The company also promotes smart, high-end, and green mine development. In 2024, it obtained the “Integration of Informatization and Industrialization” (A-level) project management capability certificate, further integrating technology, products, and management to lay a foundation for new industrialization. Zangge Potash Fertilizer prioritizes social responsibility, supporting rural poverty alleviation, education, disaster relief, and other public welfare projects, with cumulative donations reaching RMB 171.83 million by the end of 2024.

Over 20 years, the company has received more than 200 awards and honors from government agencies and industry associations, including “National Quality Exempt Product,” “Top Ten Chinese Potash Fertilizer Brands,” “Advanced Taxpayer,” “Advanced Industrial Operation Unit,” “Earthquake Relief Advanced Collective,” “Excellent Enterprise of Qinghai Province,” “National Green Mine Pilot Unit,” “Top 50 Qinghai Enterprises,” “Technological Innovation Advanced Enterprise,” “Meritorious Enterprise in China Potash Industry,” and the “Science Progress Award” from the China Inorganic Salt Association. As a pioneer in China’s salt lake development, Zangge Potash Fertilizer has accumulated rich experience in production and management, laying a solid foundation for industrial optimization and diversified development. Moving forward, the company will strengthen systems, enhance operational efficiency, improve mining processes in Chaka Salt Lake, accelerate Laos potash projects, and through continuous technological innovation, build a global benchmark for potash development and ecological protection, ensuring national food security.
