Gold ore is an important strategic mineral resource, and its efficient and green mining is the core direction of the high-quality development of the mining industry, bearing on resource security and the sustainable development of the sector. At present, with the gradual depletion of easily treatable gold ore resources, the development of refractory gold ore has become a focus of the industry. The complex mineral composition of such gold ore leads to great difficulty in gold extraction and places higher demands on the performance of auxiliary reagents in the mining process. Relying on its core characteristics such as unique strong oxidizability and environmental friendliness, sodium persulfate has become a high-quality auxiliary reagent in the mining of refractory gold ore and plays a key role in the gold extraction process.
Oxidatively Decomposes Sulfides to Facilitate the Exposure of Gold Particles
Gold in refractory gold ore is often tightly encapsulated by various sulfide minerals such as pyrite and arsenopyrite. These sulfides not only have a stable structure but also form a natural physical and chemical barrier that hinders gold extraction. This makes it difficult for conventional processes to effectively contact and extract gold particles, severely restricting the comprehensive utilization efficiency of gold ore resources. As a high-performance strong oxidant, sodium persulfate can effectively and selectively oxidize and decompose such sulfide minerals under suitable reaction conditions (e.g., acidic system, mild temperature) without damaging the gold particles themselves. Its reaction process can destroy the crystal structure of sulfides, fully exposing the gold particles originally encapsulated inside to the mining system. This creates favorable conditions for the contact and dissolution between the subsequent leaching agent and gold particles, thus breaking the extraction bottleneck of refractory gold ore and laying a foundation for the efficient leaching of gold. As a professional manufacturer of sodium persulfate, Fujian Zhanhua Chemical produces products with a high sodium persulfate content (≥99.0%), low impurity content and stable oxidation activity. This ensures the stable exertion of strong oxidizability in the process of oxidizing and decomposing sulfides, avoiding the impact of impurity interference on reaction efficiency or the generation of adverse side reactions, and providing a reliable reagent guarantee for the efficient and stable progress of gold mine mining.
Optimizes the Mining Process and Improves Production Adaptability
The mining process of refractory gold ore is often faced with problems such as complex procedures, harsh conditions and limited efficiency, which places high demands on the process adaptability of auxiliary reagents. Sodium persulfate has excellent process compatibility: it can be seamlessly integrated into various gold ore leaching processes such as cyanidation leaching, heap leaching and bioleaching without large-scale transformation of existing mining equipment and core processes, effectively reducing the cost and cycle of enterprise process upgrading. It is suitable not only for large mines but also for the transformation needs of small and medium-sized mines. It can play a stable role under conventional production conditions, optimize the oxidation environment of the leaching system, reduce invalid consumption, improve the overall production efficiency and recovery rate, and at the same time lower the difficulty of process control, helping mines realize large-scale and efficient production. The sodium persulfate products produced by Fujian Zhanhua Chemical have good water solubility and convenient operation. When stored in strict accordance with MSDS requirements, they maintain high stability at room temperature and controllable hygroscopy to prevent caking. The powder form is easy for storage and can be accurately adapted to various process scenarios in the gold mine mining process, avoiding the impact of reagent characteristic problems on process stability and providing a reliable guarantee for the standardization and high efficiency of the mining process.
Boasts Environmental and Safety Advantages to Boost Green Transformation
With the increasingly stringent national environmental protection laws and regulations, green and low-carbon development has become an inevitable trend for the transformation and development of mining enterprises. Environmental compliance and safety control in the mining process are becoming more and more important, bearing on the compliant operation and long-term development of enterprises. Compared with traditional mining auxiliary reagents, sodium persulfate has remarkable environmental and safety advantages, which perfectly align with the policy orientation of green mine development and the industry's development needs. Sodium persulfate itself has low toxicity, and its main decomposition products during mining are sulfates, with no toxic and harmful residues. It will not cause secondary pollution to soil and water bodies, demonstrating outstanding environmental friendliness. At the same time, its characteristics of low toxicity, non-flammability and non-explosiveness reduce the safety risks and treatment costs in all links such as transportation, storage, use and tailings disposal. It meets the requirements of environmental protection laws and regulations, helps mining enterprises realize clean production, and promotes the development of the mining industry towards a green, safe and sustainable direction.
Fujian Zhanhua Chemical has a mature production process for sodium persulfate, and its products are recognized as a National Single Champion Product by the Ministry of Industry and Information Technology. As a National Green Factory, the enterprise's product quality has passed strict market verification. It not only fully complies with industry standards in terms of environmental indicators but also achieves efficient pollution control and energy conservation in the production process, ensuring the green attributes of products from the source and providing high-quality and reliable reagent support for the green transformation of mining enterprises.
In the mining of refractory gold ore, sodium persulfate accurately solves the core problems such as low extraction efficiency and high environmental pressure of refractory gold ore through the targeted oxidative decomposition of sulfides, excellent process adaptability and its prominent environmental and safety advantages, providing strong technical support for the efficient, green and safe recovery of gold ore resources. With the further development of refractory gold ore exploitation, its application value and industrial importance in the field of gold mine mining will become increasingly prominent, and the stable supply of high-quality sodium persulfate products will also become an important guarantee for promoting the green mining of gold ore.
