Here are three real examples showing how our sample service helps mining and industrial clients find reliable carbon suppliers.
Case 1: Gold Mine Client from Sudan (CIL Gold Recovery Carbon)
Sample Request: Early March 2026

The client runs a medium-scale gold mine using the CIL process. They needed 6–12 mesh coconut shell carbon that’s hard, has low abrasion, high iodine (≥1200 mg/g), and produces minimal fine dust to keep their adsorption tanks running smoothly.Our Service:
We sent a free 1kg test sample within two working days, tailored to their requested mesh size. Full lab reports were included: iodine value, particle strength, ash, and moisture.Communication:
The client tested the carbon for 18 days and reached out with questions about carbon loss at their pulp concentration. We provided guidance on dosing and regeneration temperature.Bulk Order: Late March 2026, 280 tons
