## Gold Recovery Activated Carbon — Specification Sheet

Use this printable checklist when comparing quotes for gold recovery carbon (CIP/CIL). It lists the parameters to verify, the values we ship, and the documents to ask for.

## 1. Core Parameters (Verified per Lot)

| Parameter | Value We Ship | Test Method |

| Raw material | 100% coconut shell (Philippines/Indonesia) | — |

| Iodine value | 1000–1300 mg/g | GB/T 12496.8 / ASTM D4607 |

| Hardness | ≥98% | GB/T 12496.6 / ASTM D3802 |

| Moisture (as packed) | ≤5% | GB/T 12496.4 |

| Ash | ≤5% | GB/T 12496.3 |

| Mesh size | 6×12 / 8×16 mesh or 3×6 mm | GB/T 12496.2 / ASTM D2862 |

| Bulk density | 0.45–0.52 g/mL | GB/T 12496.1 |

*Spec tolerances on every contract: iodine ±50 mg/g of target, hardness at/above agreed minimum, moisture ≤5%, fines within agreed range.*

**Standard compliance:** Produced and tested against the key requirements of **YS/T 3038—2020** (Granular Activated Carbon for Gold Production).

**K-value / R-value (gold adsorption dynamics):** K-value (gold loading capacity, mg Au/g) and R-value (adsorption rate) are tested in our own QC laboratory per **GB/T 32992—2016**, with the result reported on the batch COA. Test parameters follow the gold-recovery application standard; for water or air treatment carbons, the relevant application standards apply.

## 2. Documents to Request (and What We Provide)

| Document | We Provide |

| COA per batch (IV, hardness, ash, moisture, mesh, test methods) | ✅ per exact lot |

| TDS (technical data sheet) | ✅ on request |

| Business license (export office + production plant) | ✅ both shown |

| English MSDS (16-section) + transport classification | ✅ UN 1362 Class 4.2 |

| Packing list, commercial invoice, CO, bill of lading | ✅ per shipment |

| K-value / R-value test report (GB/T 32992—2016) | ✅ in-house QC, every batch — with COA |

## 3. Buying Checklist for CIP/CIL Buyers

- ☐ Confirm your process: CIP or CIL, target iodine, hardness, mesh

- ☐ Order a **3-grade sample pack** (iodine 1000/1100/1200) with COA — test on your own liquor

- ☐ Verify COA test methods (GB/T or ASTM) — compare apples to apples

- ☐ Check fines / platelet content — high fines = carbon loss in circuit

- ☐ Lock spec tolerances and replacement terms in the contract

- ☐ Confirm packing for your inland route (moisture-proof jumbo bags, pallets)

- ☐ Arrange third-party inspection (SGS etc.) for container orders if needed

### Print This Sheet, Then Send Us Your Spec
