Star Grace Mining Co.

What Star Grace Mining Co. does

Star Grace Mining Co., Ltd. is a privately-held Chinese mining and manufacturing company established in 1990 and headquartered in Dalian, Liaoning Province. The company extracts magnesite from a mine in northern Liaoning Province — China's 'Capital of Magnesium' — with reserves sufficient for approximately 100 years of continuous extraction at 100,000 tonnes/year. Its core operations cover magnesium oxide (MgO) in grades from 60% to 94%, magnesium sulfate (heptahydrate and kieserite/monohydrate), brucite, dead-burned magnesia (DBM), and fused magnesite, produced through 32 calcination furnaces and 5 Raymond mills with a combined annual capacity of 300,000 tonnes.

The group operates through three production subsidiaries — Star Grace Mining Co., Ltd. (MgO and DBM), Star Grace Agriculture Co., Ltd. (magnesium sulfate heptahydrate and kieserite), and Star Grace Chemical (Dalian) Co., Limited (industrial chemicals) — and a Hong Kong-based sister company, CR International (Hongkong) Limited (established 2020), which handles export of magnesium, phosphate, and nitrogen fertilizers. Beyond the core magnesium range, the catalog extends to NPK, nitrogen, phosphate, potassium, zinc, and ferrous sulfate fertilizers, animal feed additives (DCP/MCP/MDCP, L-lysine, sodium bicarbonate), and industrial chemicals including coating acrylates, butyl acetate, SLES/STPP, phosphoric acid, TDI/polyols, and water-treatment chemicals.

Star Grace is a B2B bulk commodity exporter selling directly to international agricultural, feed, and industrial buyers in Latin America, Southeast Asia, Europe, Africa, and Oceania — roughly 45+ countries. Distribution runs through Dalian container port (250+ containers/week) and Bayuquan breakbulk port (6,000MT/month to South America), supported by a 13-language multilingual website that functions as the primary marketing and inquiry channel. The company holds ISO9001, ISO14001, FAMI-QS, and REACH certifications for international market access; pricing is quote-based and not publicly disclosed. The company does not disclose revenue, and operates with a lean 11–50 person headcount.
