YHGOLD Grade Activated Carbon For Gold Recovery

YHGOLD series metallurgical‑grade activated carbon is premium regenerable granular activated carbon manufactured from high‑grade mature coconut shell charcoal via high‑temperature steam activation process, specially engineered for precious‑metal cyanide leaching and gold elution‑regeneration operations.

The product features well‑developed microporous pore architecture optimized for selective adsorption of gold‑cyanide complex ions. Strict raw‑material screening, carbonization, activation, crushing, screening and dedusting procedures deliver outstanding mechanical hardness, low attrition loss, minimal platelet content and stable batch‑to‑batch consistency.

When deployed in slurry‑based gold extraction circuits, YHGOLD carbon maintains fast gold loading kinetics, high volumetric activity and elevated gold loading capacity, while lowering soluble gold losses caused by carbon fines. Multiple thermal reactivation cycles are supported, helping mines cut carbon consumption and operating expenditure. Four grades are available covering iodine values from 1050 mg/g up to 1200 mg/g to match different ore conditions, throughput demands and process configurations for global gold mining projects across Africa, Southeast Asia and Latin America.

Core Product Advantages

• Optimized micropore structure for high gold‑cyanide complex adsorption performance
• Superior ball‑pan hardness & low attrition rate, reducing fine‑carbon‑driven gold tailings loss
• Low platelet content and rigorous de‑dusting treatment, less screen clogging risk
• High volumetric activity and higher gold loading capacity
• Good re‑generability, suitable for repeated thermal reactivation in on‑site kilns
• Multiple grades & mesh options for CIP, CIL, CIC and heap‑leach gold recovery workflows

Note: K‑value and R‑value reflect real‑world gold adsorption capacity and kinetic speed. Batch COA documents including iodine, hardness, particle‑size distribution are supplied per shipment. Third‑party inspection reports are available upon request.

YHGOLD metallurgical‑grade coconut shell activated carbon is widely adopted for precious‑metal extraction circuits in global gold‑mining operations:

1. Carbon‑in‑Pulp (CIP) Circuits: Gold adsorption after cyanide leaching of ore pulp, stable high‑throughput operation
2. Carbon‑in‑Leach (CIL) Circuits: Simultaneous leaching and gold adsorption, ideal for preg‑robbing carbon‑bearing oresCalgon Car...
3. Carbon‑in‑Column (CIC) Circuits: Heap‑leach pregnant‑solution adsorption in fixed carbon columns
4. Gold elution & thermal reactivation systems, repeated carbon regeneration cycles
5. Secondary recovery of silver and platinum‑group metals from cyanide leachate
6. Gold‑mine solution purification and cementation supporting processes

Mesh selection guidance:

• 6×12 mesh: Global mainstream standard for CIP / CIL, balances screening efficiency and gold‑loading kinetics, low carbon carry‑over loss
• 8×16 mesh: Faster adsorption kinetics, fit for CIC column‑type systems with well‑controlled screening
• 6×16 mesh: Intermediate option for mixed‑condition mining sites

Q1: Which YHGOLD grade should I select for my plant?

A: For conventional CIP/CIL circuits, YHGOLD GRADE 1901 (1050 mg/g iodine) works well for general‑grade ores. High‑throughput plants or preg‑robbing carbon‑rich ores are recommended to choose GRADE 1902 / 1903. YHGOLD GRADE 2000 (1200 mg/g iodine) is the premium choice for demanding high‑gold‑loading scenarios. Share your ore characteristics, circuit type and throughput, and our technical team can deliver targeted recommendations.

Q2: Why is hardness and attrition so critical for gold‑recovery activated carbon?

A: Carbon is continuously agitated, pumped and screened inside ore slurry. Low‑hardness carbon breaks easily and generates fine particles. Carbon fines loaded with gold pass through safety screens into tailings ponds, directly causing irreversible gold loss and increasing carbon make‑up costs. Our YHGOLD series maintains ≥ 98.5 % ball‑pan hardness to minimize fine generation over multiple re‑activation cycles.

Q3: How many re‑activation cycles can YHGOLD carbon sustain?

A: Under proper thermal re‑activation operation, YHGOLD carbon can achieve 5‑8 effective re‑activation cycles before major replacement. Service life varies according to ore abrasiveness, elution‑regeneration operation quality and on‑site screening performance. Strict batch‑consistent quality helps extend service life and stabilize your gold‑recovery rate.

Q4: What is the difference between iodine number and K‑value?

A: Iodine number reflects overall micropore volume, while K‑value directly characterizes real gold‑loading capacity under mining‑simulated conditions. Higher iodine provides a good foundation, yet you should evaluate both K‑value and R‑value (adsorption kinetic rate) to judge actual gold‑capture performance of activated carbon, instead of only comparing iodine‑number figures.

Q5: What is your MOQ and sample policy?

A: Standard minimum order quantity for YHGOLD series is 5 tons. Plant‑trial samples are available. Contact sales team for sample specifications, shipping arrangement and quotation. Every commercial shipment comes with complete batch COA documentation.

Q6: What lead‑time and delivery terms can you offer?

A: Normal production lead‑time is 10‑15 working days for standard‑spec bulk orders. We support FOB major Chinese ports, and can coordinate DDP services for mining destinations in Africa and other regions.
