China's 14th Five-Year Plan explicitly mandates strengthening rubidium and cesium resource security. Jinyinhé Company—as the world's first enterprise to achieve full production capacity for its thousand-ton-scale high-purity rubidium-cesium salt recrystallization project—has now reached full operational capacity.

Jinyinhé's thousand-ton-scale cesium-rubidium salt project leverages the company's proprietary two-stage low-temperature sulfation ore-phase restructuring technology. This technology represents the world's first fully enclosed continuous production process and equipment line, enabling high-value utilization of all elements—including lithium, rubidium, cesium, potassium, vanadium, and faraway—from lithium mica. It has fundamentally restructured the resource value of China's low-grade lithium mica industry. The project comprises two main production lines: low-temperature sulfuric acid mica lithium extraction and rubidium-cesium salt recrystallization. Key products include battery-grade lithium carbonate, industrial-grade lithium carbonate, rubidium salt (99.9%), cesium salt (99.9%), potassium alum, potassium sulfate, and silica sand.

By mid-October 2025, the company's thousand-ton-scale high-purity rubidium-cesium salt production line had successfully achieved full capacity.
