Factory vs Trader ## Factory vs Trader — What It Changes for You Buying carbon from a factory is not the same as buying through a trading company. Here is what changes for your operation. | What changes for you | Factory (YELI Carbon) | Trading company | | **Price** | Factory-direct, no middleman — you pay the plant's price, not a reseller's margin | A markup on top of another factory's price; quotes can shift as the trader changes supply sources | | **Quality control** | In-house QC on every lot — hardness, iodine, moisture and ash tested at our plant | QC is done by whoever made the carbon; the trader mostly passes the certificate through | | **COA authenticity** | COA issued for every batch, straight from the production line, with the test method on it | Certificates can be copied or mixed between suppliers — hard to verify at arm's length | | **Custom specs** | Mesh cut, hardness target, iodine range and packing can be adjusted on our own lines | Limited to whatever the underlying factory already produces | | **Lead time** | Production and dispatch under one roof — 24 h response, loading from our 4,000 m² packing and dispatch area | An extra step between the factory and your container; delays depend on a third party | | **Accountability** | One company owns the plant, the QC and the shipment — a single point of responsibility | If quality or delivery fails, trader and factory can point at each other | Typical plant-practice numbers for gold-grade coconut carbon: hardness **96–99%** (ASTM D3802 ball-pan method; coal-based grades run **90–95%**), make-up carbon **20–100 g** per tonne of ore, regeneration mass loss **5–15%** per cycle, iodine **1000–1300 mg/g** and gas-phase CTC **30–90%**. These are typical industry ranges — tell us your circuit and we will spec the carbon to it. Experience ## 20+ Years Behind Every Batch Gold recovery carbon is not an off-the-shelf product. It takes production know-how to get the hardness, kinetics and consistency that CIP / CIL circuits demand. 🔬 ### Deep Production Experience More than two decades of activated carbon manufacturing, with a long track record in gold-leaching grade coconut shell carbon for mining customers. ⚡ ### Dedicated Gold-Grade Lines Specialized production lines for CIP / CIL carbon — engineered for high loading rate, fast kinetics and low attrition in gold recovery circuits. 🌍 ### Validated in Gold Mining Regions Our grades are proven in real mining operations, with wide market validation across Africa and other gold-producing regions. Stable Supply ## Supply You Can Rely On A mine cannot stop production because of a missing shipment. Our factory structure exists to keep your supply stable. **100%**In-house production & QC on every lot **25 kg / 1 MT**Export bags and jumbo bags, container-ready **≥8,000 MT**Annual gold-grade production capacity **24 h**Response to inquiries, day and night [Factory address] ### Visit Our Factory Production Plant: No.52 Yanling West Road, Yanshi Town, Xinluo District, Longyan City, Fujian Province, China 生产车间：福建省龙岩市新罗区雁石镇雁岭西路52号生产车间 Export office: Room 2604-4, No.6 Hubin East Road, Siming District, Xiamen City, China +86 136 0090 6330 (tel:+8613600906330) · info@yelicarbon.com (mailto:info@yelicarbon.com) Buyer Q&A ## Questions Mining Buyers Ask Before Ordering Are you a real factory or a trading company? + We are a real factory.
