YX500 Eco‑Friendly Non‑Cyanide Gold Leaching Reagent
YX500 is proprietary low‑toxic cyanide‑free composite gold leaching reagent independently developed by Y&X Beijing Technology Co., Ltd. It acts as a direct replacement for sodium cyanide for gold‑silver extraction. No major reconstruction required for existing CIL, CIP, heap leaching, tank leaching and stirred leaching plants. It delivers comparable gold leaching performance under proper metallurgical conditions. Suitable for oxide gold‑silver ore, partial primary gold ore, cyanidation tailings, gold concentrate, roasting slag and anode mud. Widely deployed for gold mine projects across Africa, Central Asia, Southeast Asia and Latin America, helping mines satisfy ESG and local environmental regulations while maintaining stable gold recovery.
Key Advantages & Product Highlights
- Direct Sodium Cyanide Replacement: Fully compatible with existing gold leaching workflow. No large‑scale equipment modification for CIL / heap‑leach plants, low conversion investment.
- Low‑toxic for Site Safety: Not classified as highly toxic hazardous poison. Minimize operator poisoning risk. Leached tailings are non‑hazardous waste and reduce tailings disposal cost.
- Convenient Global Shipping & Storage: General chemical commodity. Simplified import procedures for countries with strict cyanide restrictions. Stable performance under normal room‑temperature storage.
- Faster Leaching Kinetics: Accelerate gold dissolution and shorten leaching cycle. Reduce water and power consumption, good compatibility with activated carbon adsorption system.
- Wide Raw‑material Compatibility: Fit for oxide ore, gold tailings, gold concentrate, roasting slag and anode mud. Supports heap leaching, tank leaching, CIP, CIL and stirred‑tank leaching.
- Complete Technical Service Package: Provide ore‑sample lab test, dosage optimization, on‑site commissioning guidance and operator training.

Typical Application Scenarios
- Medium‑small oxide gold mine heap‑leaching projects where sodium cyanide import is restricted by local regulations.
- Existing CIL / CIP gold processing plant seeking eco‑friendly alternatives to lower environmental risks.
- Retreatment of historic cyanide gold tailings for residual gold recovery.
- Leaching for gold‑silver concentrate, anode mud and precious‑metal secondary resources.
⚠️ Note: Pretreatment is required for high‑sulfur, high‑arsenic refractory gold ore. Ore‑sample laboratory test is strongly recommended before bulk purchase.
FAQ
Can YX500 replace sodium cyanide without modifying my existing CIL plant?
Yes. YX500 supports seamless substitution. You can retain existing agitation tanks, carbon adsorption system, thickeners and pipelines. Only dosing rate and pH parameters need fine‑tuning based on ore testing. Major equipment reconstruction is not required.
What gold recovery rate can be achieved comparing with sodium cyanide?
For oxide gold ore and low‑refractory ore, gold leaching recovery can reach a comparable level to sodium cyanide with optimized dosage. Performance varies for high‑sulfur / high‑arsenic refractory ore. Please send ore samples for lab leaching test to obtain real benchmark data before site application.
Are YX500 and leached tailings hazardous?
YX500 is low‑toxic general‑purpose chemical instead of lethal poison like sodium cyanide, greatly reducing on‑site safety risks. Post‑leaching tailings are non‑hazardous waste and cut tailings pond management & remediation costs. Standard PPE procedures must still be followed during reagent dissolving and production operations.
Can you ship YX500 to my country? Is import approval complicated?
As general chemical commodity, YX500 has far simpler import formalities than sodium cyanide in most countries. We provide complete shipping documents including MSDS, packing list and commercial invoice. Please advise your destination country in advance so we can verify local import requirements.
What preparations should I complete before on‑site application?
Please send representative ore samples for laboratory leaching tests. We confirm optimal reagent dosage, pH window, leaching duration and expected gold recovery. Our metallurgical engineers can travel to mine‑site for commissioning and operator training upon request.
What are storage requirements and shelf‑life for YX500?
Store in dry, ventilated room‑temperature warehouse, keep away from moisture and rain. Valid shelf‑life reaches 24‑months under proper storage conditions. Seal packaging tightly after partial use.
What technical support can Y&X provide besides supplying chemicals?
We deliver ore‑sample lab analysis, leaching‑condition testing, technical datasheet, on‑site commissioning guidance, operator training and long‑term technical consultation. We provide complete leaching solution rather than only chemical products.
Is YX500 mechanical equipment or consumable?
YX500 is a mining beneficiation chemical consumable, not machinery equipment. It is continuously consumed during gold leaching production and requires regular bulk procurement, same category as flotation collectors, frothers and flocculants.
