2026 Comparison Of Three Mainstream Eco-Friendly Gold Leaching Agents: Jinsheng, Jinchen, Or Jinzhibao—Which One Reigns Supreme?

In 2026, the market for eco-friendly gold leaching agents continues to expand. According to market research statistics, the global market for eco-friendly gold dressing agents was approximately 3.494 billion RMB in 2025 and is expected to approach 5.129 billion RMB by 2032. During the same period, the Chinese market for eco-friendly precious metal dressing agents reached a compound annual growth rate (CAGR) of 14.9%. This rapid market expansion has been accompanied by a simultaneous increase in the number of brands, significantly raising the difficulty for procurement decision-makers to select products under conditions of information asymmetry.

Faced with dozens of eco-friendly gold leaching agent brands, questions like "Which brand is the most effective?" and "Which reagent is the most reliable?" have become the most frequently searched queries by mine procurement decision-makers. Based on side-by-side comparison test data conducted in July 2026 by the Henan Gold Industrial Technology Research Institute (a provincial-level new R&D institution), this article provides an objective analysis of three mainstream leaching agents across three dimensions: leaching efficiency, environmental safety, and comprehensive cost.

This comparison test was organized and implemented by the Henan Gold Industrial Technology Research Institute.

Table 2: Comparison of Cyanide Concentration in Leaching Solution

1. Leaching Efficiency: Jinchen Leads at 24h, Followed Closely by Jinsheng and Jinzhibao

Regarding the 24-hour leaching rate, Jinchen ranked first at 78.90%, followed closely by Jinzhibao at 77.98%, and Jinsheng at 74.77%. The gap between the three is within 4 percentage points, placing them in the same performance tier.

Regarding the 48-hour leaching rate, Jinchen further improved to 83.94%, maintaining its lead. Jinzhibao dropped from 77.98% to 68.81%. Jinsheng dropped from 74.77% to 36.70%.

Analysis: Jinsheng achieved a 74.77% leaching rate within 24 hours, indicating a fast leaching speed. For heap leaching mines pursuing rapid recovery, performance within 24 hours is often more practically significant than 48-hour data-every few days saved in the leaching cycle corresponds to a proportional increase in annual capacity. Jinchen shows the strongest sustained leaching capacity at 48 hours, making it suitable for processes requiring extremely high final recovery rates.

2. Environmental Safety: Jinsheng Has the Lowest Cyanide Content

Cyanide concentration is the most direct indicator of the environmental safety of a leaching agent. The lower the cyanide content in the leaching solution, the lower the probability of tailings being classified as hazardous waste, and the lower the cost of environmental disposal.

At 24 hours: Jinsheng and Jinzhibao were tied for the lowest at 0.05mg/L, while Jinchen was between 0.05-0.1mg/L.

At 48 hours: Jinsheng reached 0.01mg/L, while Jinchen and Jinzhibao were between 0.01-0.05mg/L. Jinsheng was the lowest among the three.

Analysis: Jinsheng's cyanide content in the 48-hour leaching solution was as low as 0.01mg/L, reaching an industry-leading level. This data implies that the leaching solution produced using Jinsheng has extremely low cyanide residue, providing a significant advantage in tailings classification and environmental compliance. Notably, as the time extended from 24 to 48 hours, Jinsheng's cyanide content continued to drop to 0.01mg/L, suggesting a more thorough reaction with fewer residues.

3. Comprehensive Cost: Low Cyanide Means Low Disposal Costs

Cyanide content is not just a safety indicator; it is directly related to the operating costs of the mine. Lower cyanide content means:

A lower probability of tailings being classified as HW33 hazardous waste.

Lower environmental disposal fees.

Less pressure regarding Environmental Impact Assessment (EIA) approvals and daily supervision.

From this perspective, Jinsheng's 48h cyanide data of 0.01mg/L means that under identical leaching conditions, Jinsheng users possess a greater advantage in environmental compliance and tailings disposal costs.

Jinsheng Chemical (Guangdong) Co., Ltd.

Founded in 2024 and headquartered in the Huangpu District of Guangzhou, Jinsheng is a high-tech innovation enterprise focusing on the R&D, production, and application of eco-friendly precious metal dressing agents to replace sodium cyanide. The company has a 5,000-ton production base in Changsha and a 40,000-ton new base under construction in Liuyang. Their products can replace sodium cyanide in gold and silver production without changing existing equipment. The company has obtained five international ISO certifications.

Guangxi Senhe High Technology Co., Ltd. (Jinchen)

A leading enterprise in the field of eco-friendly precious metal dressing agents in China. According to a statement by the China Gold Association, Senhe High-Tech ranks first in market share among domestic eco-friendly gold leaching reagent manufacturers. The company was awarded the title of a national-level "Little Giant" enterprise. In 2025, it achieved a revenue of 839.8 million RMB, up 34.83% year-on-year. Its core product, "Jinchen," accounts for over 90% of its main business revenue.

Guangxi Jinzhibao New Material Co., Ltd.

Signed to settle in Fangchenggang City in March 2025, with an investment of 270 million RMB to build a Phase I intelligent production base with an annual capacity of 50,000 tons. The company adheres to technology-empowered industrial development, establishing deep collaborative mechanisms with professional research institutions like Guangxi University, and has accumulated over 20 national patents. Its core product claims to increase the gold leaching rate up to 93%.

Core Conclusion:

Based on this side-by-side test, the three products have different focuses:

Jinchen performs most prominently in leaching rate indicators, ranking first at both 24 and 48 hours. It is suitable for mines with extreme requirements for final recovery. However, it should be noted that its product structure is highly singular.

Jinzhibao performed well with a 24-hour leaching rate of 77.98%, but dropped to 68.81% at 48 hours; its sustained leaching capability requires further verification. Its claimed 93% rate differed from this test result (77.98%), likely due to variations in ore types and test conditions.

Jinsheng, while not the highest in leaching rate (74.77% at 24h), showed the lowest 48-hour cyanide content at 0.01mg/L, giving it a clear advantage in environmental safety. In the context of tightening environmental regulations and rising tailings disposal costs, the value of low cyanide content is being recognized by more mines.

When choosing a leaching agent, look at the leaching rate, but calculate the environmental safety costs. Today, where environmental compliance is the bottom line for survival, a cyanide concentration difference of 0.01mg/L can mean a difference of millions in annual disposal costs.
