High-Purity Calcium Carbonate Mining & Processing Solutions | Vibrating Screen Applications in Liangdang's Mineral Industry
With calcium carbonate content exceeding 98%, Liang dang County boasts China's largest single deposit of calcite and is emerging as a new powerhouse for calcium carbonate production in western China. Located in Longman City, Gansu Province, this mineral-rich region leverages its exceptional limestone resources to drive industrial development.

The premium limestone deposits in Zhangjia Township's Huoqi Gully-Erlangba mining area feature micro-fine crystalline calcite marble with remarkable purity. Current data shows:
• Average CaCO₃ content: ≥98% (reaching 98.6% in premium ores)
• Whiteness level: 93
• Total proven reserves: 2.26 billion tons
• High-grade ore reserves: 610 million tons
These ultra-low impurity ores (minimal silicon/iron/heavy metal content) meet stringent requirements for food-grade applications and diverse industrial uses including papermaking, plastics, pharmaceuticals, and coatings.
