Activated Carbon for Gold Recovery / 黄金提取用椰壳活性炭
Description
High-hardness coconut shell granular activated carbon for gold recovery in CIP, CIL, CIC and heap-leach circuits. The carbon is intended to maintain stable adsorption performance and mechanical strength through repeated handling, screening, elution and regeneration, helping reduce carbon breakage, fines and loss of gold-loaded carbon.
Applications: CIP (Carbon-in-Pulp), CIL (Carbon-in-Leach), CIC (Carbon-in-Column), heap-leach gold recovery.
Specifications:
- Appearance: Black granules
- Particle size: 5×10 / 6×12 / 6×16 / 8×16 mesh. All four sizes are available. Other particle sizes can be confirmed according to plant requirements.
- Iodine value: 950–1250 mg/g. A specific iodine value can be confirmed on request.
- Moisture content: ≤5%
- Ash content: ≤3%
- Hardness: ≥98.5%. Higher hardness can be supplied according to the agreed specification.
In CIP, the ore is leached before activated carbon is introduced into the slurry. In CIL, leaching and carbon adsorption take place in the same series of tanks. In CIC, gold-bearing solution flows through columns containing activated carbon; this method is commonly used for clarified solution, including pregnant solution from heap leaching. In heap-leach operations, the carbon is normally used to treat the collected solution rather than being mixed directly into the ore heap. Performance depends not only on adsorption capacity, but also on mechanical strength, particle size distribution, pore structure and resistance to attrition. High hardness helps reduce carbon breakage, fine carbon generation, carbon loss during circulation, screening problems and loss of gold-loaded carbon.
Packaging: Standard export packaging: 25 kg woven bags with inner polyethylene liner; palletized packaging available upon request; jumbo bags can be supplied for suitable bulk orders; customized marks and labels available according to order requirements.
MOQ: 5 tons, with special cases negotiable.
Sample: Free 1 kg sample, freight collect or quoted separately.
Lead time: Depends on quantity, specification and schedule, and is confirmed at quotation.
Documents: COA, TDS, packing list, commercial invoice and certificate of origin (when required).
高强度椰壳颗粒活性炭，适用于黄金提取过程中的炭浆法（CIP）、炭浸法（CIL）、炭柱法（CIC）及堆浸提金。本品需在反复输送、筛分、解吸和再生过程中保持稳定的吸附性能和机械强度，以减少炭损耗和已载金细炭流失。
用途：炭浆法（CIP）、炭浸法（CIL）、炭柱法（CIC）、堆浸提金。
规格：
- 外观：黑色颗粒
- 粒径：5×10 / 6×12 / 6×16 / 8×16 mesh。以上四种目数均有供应，也可按选厂要求确认其他目数。
- 碘值：950–1250 mg/g。可按要求确认具体碘值。
- 水分：≤5%
- 灰分：≤3%
- 硬度：≥98.5%。也可按约定规格提供更高硬度。
CIP：矿石先浸出，再将活性炭加入矿浆，溶解金由溶液转移到活性炭上。CIL：浸出与炭吸附在同一系列槽内同时进行。CIC：含金溶液流经装填活性炭的炭柱，常用于澄清液，包括堆浸所得贵液。堆浸：矿石堆淋浸出后，通常用炭柱回收溶液中的金，而不是把炭直接混入矿堆。提金炭不仅要看吸附能力，还要看机械强度、粒径分布、孔隙结构和耐磨性。较高的硬度有助于减少碎炭、细炭产生、循环过程中的炭损、筛分问题以及载金炭流失。
包装：常规出口包装：25公斤内衬聚乙烯薄膜的编织袋；可根据要求提供托盘包装；适合的大宗订单可提供吨袋；唛头和标签可按订单要求定制。
最小起订量：5吨；特殊情况可协商。
