With increasingly stringent national environmental policies, green mining construction has become an inevitable trend for the mining industry. In 2026, the Ministry of Natural Resources released the "Green Mining Construction Evaluation Indicators (2026 Edition)," setting higher requirements for environmental protection, resource utilization, and energy conservation. As key auxiliary materials in the mineral processing, the environmental performance of flotation reagents directly affects mining green ratings.

Key Points of 2026 Green Mining New Regulations

The new evaluation indicators mainly emphasize the following aspects regarding reagent usage:

• Limiting toxic and hazardous substances: Strictly controlling impurity content in traditional reagents such as xanthates and dithiophosphates, particularly heavy metals and sulfides
• Promoting low-toxicity environmental reagents: Encouraging the use of collectors and frothers with good biodegradability and low toxicity
• Wastewater treatment and recycling: Requiring mineral processing wastewater recycling rates of no less than 85%, with reagent residues meeting discharge standards
• Whole-process environmental management: Establishing comprehensive environmental management systems from reagent procurement, storage, use to waste disposal

Environmental Flotation Reagent Selection Guide

Faced with new regulatory requirements, mining enterprises should focus on the following aspects when selecting flotation reagents:

1. Collector Selection: Prioritize environmentally friendly collectors with high selectivity and low dosage. New ester-type collectors have better biodegradability compared to traditional xanthates, with less long-term environmental impact. For copper, lead, and zinc sulfide ores, thiocarbamate collectors can be considered as alternatives to some dithiophosphate products.

2. Frother Optimization: Choose low-toxicity, low-residue frother products. MIBC (methyl isobutyl carbinol), as a traditional frother, while performance-stable, is relatively volatile. New polyether frothers offer better environmental performance and excellent frothing capabilities, serving as viable alternatives.

3. Reagent Combination Optimization: Through scientific reagent system design, reduce total reagent usage while ensuring mineral processing indicators. Adopt a "less but better" strategy to both reduce costs and environmental burden.

Implementation Recommendations

Regarding the 2026 new regulations, mining enterprises are recommended to take the following measures:

First, comprehensively assess current reagent usage and conduct gap analysis against new regulatory requirements. Second, cooperate with professional reagent suppliers to develop reagent substitution and optimization plans. Third, establish reagent usage records and improve environmental management systems. Finally, strengthen employee training to enhance environmental awareness and operational skills.

Green mining construction is a systematic project requiring joint efforts from mining enterprises, reagent suppliers, equipment manufacturers, and other stakeholders. Qingdao Ruchang is willing to work hand in hand with mining enterprises to jointly promote mining green transformation, achieving win-win economic and environmental benefits.
