Salaria also criticised the annual benchmark mechanism for copper concentrate treatment and refining charges (TC/RCs), usually agreed in November by a leading miner and a Chinese smelter, sayingThe head grade of copper in the ore is 1–2% and the oxidation state is ~60% [ 26 ]. The decision to use the combined technology for processing ores with the ultimate recovery of copper into a bulk concentrate (~90%), its low copper content (~5–6% copper), and the decrease in copper loss with tailings was taken after numerous tests.Current Status of Copper-Ore Processing: A Review

The price of the raw materials shall be the sum of the values of the payable metals less the sum of the deductions. The refining charge for payable copper shall be 4.5 USc per pound of payable copper. Example) For a concentrate with a copper content of 24% the payable copper value is 24% 1 %-unit = 23%. 23% x 22.046 x 4.5 USc/lb = Given that the price coefficient for domestic copper concentrate was close to smelters' production cost in late 2020, the room for increase would be limited, and the best guess is that the overall price coefficient would inch up by 0.3-0.7 percentage points in 2021.

Copper smelting open-circuit (CSO) dust contains various valuable metals, such as copper, lead, and zinc, as well as undesirable toxic elements such as arsenic. Thus, the comprehensive recovery of valuable elements from CSO dust is highly significant from both economic and environmental perspectives.

Flotation is a common mineral processing method used to upgrade copper sulfide ores; in this method, copper sulfide mineral particles are concentrated in froth, and associated gangue minerals are separated as tailings. However, a significant amount of copper is lost into tailings during the processing; therefore, tailings can be considered A typical treatment charge is US$45/dry metric tonne (DMT) of concentrate. A typical refining charge is 4.5US¢/lb of payable copper (Söderström, 2008), which approximately equates to US$23/DMT of concentrate, for concentrate with a Cu grade of ∼24 wt%.
