What Copper Concentrate Is
Copper concentrate is a partly refined product created by crushing and processing copper ore to raise its copper content, typically to 20–30% Cu or higher. Smelters import concentrate as feedstock to produce refined copper. Because value depends on copper content, accurate assay verification is central to every transaction.
Understanding Cu Content and Assays
The copper grade (Cu%) is the headline figure, but buyers also assess moisture content, impurities, and deleterious elements. A detailed assay report accompanies quality shipments so smelters can calculate payable metal. Our copper concentrate is supplied with assay documentation for each consignment.
How Concentrate Pricing Works
Concentrate is priced against the copper market value, adjusted by treatment and refining charges (TC/RC) and the payable metal percentage. Higher Cu content and lower impurities improve the buyer’s economics.
Shipping Copper Concentrate in Bulk
Concentrate ships in bulk bags or containers by sea freight. Moisture management and proper packaging matter to prevent loss and meet transport safety rules. We coordinate export clearance and documentation to destination ports for buyers in China, Japan, and Canada.
What Smelters Should Verify
Confirm Cu content via assay, check moisture and impurity levels, agree on inspection terms, and clarify TC/RC charges. These steps ensure the delivered concentrate matches contract terms.
