Mineral refining
BUY GOLD CO supplies verified copper concentrate to industrial buyers who need consistent grade and impurity control. We source from licensed operations in South Africa and Ghana, verify moisture and arsenic levels on-site, and provide lab-certified data that matches refinery intake specs. In industrial supply, tolerance isn’t flexibility it’s failure.
Challenge
An electronics manufacturer in China rejected two prior African copper shipments due to unverified arsenic levels and inconsistent moisture content. The variability disrupted their smelting process and triggered costly production line stoppages.
Solution
We sourced 12 tonnes of copper concentrate from a DMRE-licensed site in Rustenburg, South Africa. Our team used a Fluke moisture meter (8.3%) and oversaw sampling for ALS Johannesburg. The assay confirmed Cu 28.6%, As 0.04%. Full GACC-aligned documentation enabled first-time clearance in Shanghai.
