Replace Cyanide New Gold Leaching Environmental-Protective Reagent YX500

Eco-Friendly Gold Leaching Reagent (YX500) - Product Introduction

The YX500 Eco-Friendly Gold Leaching Reagent, developed by Y&X Beijing Technology Co., Ltd., is a state-of-the-art alternative to sodium cyanide, widely used in gold beneficiation and smelting processes. This innovative product has complete independent intellectual property rights and has been industrialized for production and application.

**Key Features:**
**Environmental Compatibility:** YX500 is an environmentally friendly leaching agent that replaces highly toxic sodium cyanide. It is composed of sodium carbonate tripolycyanate, alkaline thiourea, alkaline polymeric iron, and carbonates, which work synergistically to complex and dissolve gold without releasing free cyanide ions, ensuring a safe and eco-friendly gold extraction process.

- **Industrial Application:** YX500 has achieved standard discharge of tailings slurry while ensuring gold leaching indicators, significantly reducing environmental impact. The technology has been appraised by the China Gold Association as innovative and reaching international advanced levels.

- **Advantages:** YX500 offers low toxicity and environmental protection, high recovery rates, good stability, convenient operation, fast recovery, reduced dosage, low cost, and ease of storage and transportation.

**Technical Specifications:**
- **Low Toxicity Principle:** The cyano-like groups in YX500 are covalently bonded, not ionically, which, along with steric hindrance, prevents the release of free cyanide ions in alkaline environments while maintaining complexation capabilities similar to free cyanide.

- **Water-Insoluble Substances:** YX500 contains a small amount of water-insoluble substances (≤3%), primarily iron-containing oxides, which further stabilize the carbonized sodium cyanurate, enhancing the product's stability and safety performance.

**Usage Guidelines:**
- **Application Range:** YX500 is applicable to a variety of gold-containing materials, including oxidized ores, primary ores, tailings, concentrates, roasting slag, and anode sludge, and is compatible with heap leaching, pool leaching, carbon slurry, and other leaching processes.

- **Product Form:** YX500 is available as a powdery solid.

- **Dissolving Method:** It is fully dissolved in water at room temperature after thorough stirring.

- **pH Adjustment:** The pH is generally maintained between 10-12 using lime or caustic soda.

- **Dosage:** YX500's dosage can refer to the amount of sodium cyanide used, with adjustments based on ore grades and impurity contents. It is typically prepared as a 15-20% solution and added at the same point as sodium cyanide.

**Environmental and Economic Benefits:**
- **Cost-Effective:** While YX500 may have higher reagent consumption for certain ores, the overall production cost is reduced when considering the reuse of leachate and the reduction in tailings treatment costs.

- **Safety and Compliance:** YX500 reduces hidden costs related to safety management and ensures continuous production in regions with unstable sodium cyanide supply.

YX500 represents a significant advancement in gold leaching technology, offering a safer, more environmentally friendly, and cost-effective solution for the gold extraction industry. It is a reliable choice for mines seeking to enhance sustainability and efficiency in their operations.
