Main Business
Mingzhu Chemical, founded in 2010, has inherited the renowned "Night Pearl" brand in the mineral processing industry. As a provider of mineral processing reagent solutions serving both domestic and international markets, the company is primarily engaged in the research and development, production, and sales of flotation reagents, including collectors, modifiers, and frothers. Its products are mainly used in the mining of precious and non-ferrous metals, offering highly efficient, low-toxicity reagent formulations and lime-free flotation processes that enhance concentrate recovery while reducing the generation of hazardous waste.
According to data from Frost & Sullivan:
In 2024, based on revenue attributable to flotation reagent product sales within China, Mingzhu Chemical ranked second among Chinese flotation reagent companies, with a market share of 1.05%.
In 2024, based on sales revenue of yellow pharmaceutical products within China, Mingzhu Chemical ranked first among China's yellow pharmaceutical companies, with a market share of 15.57%.
Mingzhu Chemical's business model is rooted in technology collaboration rather than mere commodity supply, embodying the "one mine, one reagent" operating philosophy. The company develops customized formulations tailored to each customer's specific ore characteristics and provides end-to-end technical services that encompass pre-sales flotation testing and analysis, on-site implementation and dynamic optimization, as well as continuous post-sales process monitoring. By leveraging its technical expertise within customers' operations, Mingzhu Chemical helps improve concentrate grade and recovery rates, thereby maximizing the value of mineral resources. Since its establishment, Mingzhu Chemical has served more than 500 clients worldwide, with operations spanning over 20 provinces, municipalities directly under the central government, and autonomous regions in mainland China, and exports to more than 15 countries.
