Introduction for Trade of Mineral ProductsBusiness ScopeCopper concentrate, gold ore and gold concentrate。Copper ConcentrateDefinitionCopper concentrate is a kind of powder products with size of 200 mesh (74um), produced by copper ore through process of crushing, milling and floatation.Method of Pricing There are two kinds of pricing methods: Ratio pricing, 2.Processing charge pricing. 2.2.1 Ratio pricing (it applies to small quantity purchasing)The calculation formula: Total price= LME (Cu) ×Ratio (%) × Content (Cu %) +Value of Gold+ Value of SilverLME (Cu): The future price of Cu in London Metal Exchange。Content (Cu %): the percentage of Cu element in copper concentrate. The pricing method of Silver (Ag) and Gold (Au) is the same with Cu. The price will not be paid if the content of Ag and Au lower than certain content, which will be discussed by buyer and seller.Ratio (%): a percentage for pricing, it’s related to the content of Cu.For example:Content Cu (%)18~18.9919~20.9921~21.9922~27.99≥28Ratio (%)60616263652.2.2 Processing Charge Pricing (It applies to international big quantity purchase)The calculation formula: Total price/metric ton= (LME (Cu) –Treatment Charge-Refining Charge) × Content (Cu %) × Payable Ratio (%) +Value of Gold+ Value of Silver.Treatment Charge＝ 1 ÷ Cu％ ÷ Payable Ratio (%) ×TCRefining Charge = 22.0462×RCTC: the treatment charge of processing the copper ore to positive plate.RC: the refining charge of processing positive plate into /link?url=Mbgko_O7obn51WXBqoVumHZmNpCntYkNrv9FlbG4__c5HgarjSKiY9j7Ks-9fuORlIpB8inPimc8yl8naRPHrjTMDP4MBQMVAXdgW-nXfb_v7g-F1ccENCKm3RGJa93yelectrolytic copperPayable Ratio: the recycling rate for smelting the ore.TC, RC and payable ratio will be negotiated by seller and buyer. Quality Control Content (%): The standard basic content of Cu is 20%. Normally, we just accept the content higher than 18%. The content, lower than 18%, is also negotiable.Quantity: the supply quantity for each time should be more tha
