Weak concentrates supplies are among other factors that have seen copper concentrate treatment and refining charges (TC/RCs) hit their lowest-ever level, with Fastmarkets’ most recent calculation of the copper concentrates TC index, cif Asia Pacific, at $(3.00) per tonne on May 10 – ...
In the copper concentrates market, the consensus is for a decline in 2025’s copper concentrates treatment and refining charge (TC/RC) benchmark, but just how much the number will fall remains a key talking point, Fastmarkets has heard. “I am still thinking next year’s copper concentrates ...
are subjected to fire refining to recover the valuable associated elements (Au, Ag, Se, Fe, Bi) and to remove the harmful impurities. This process is based on the greater affinity (than that of copper) of the impurity metals for oxygen: Fe, Zn, Co, some of the Ni, and other metals...
Copper treatment and refining charges declined for a thirdconsecutive month in January, pushing the Metal Bulletin CopperConcentrates Index to its lowest level since August.The index was calculated at $90.40 per dry metric tonne/9.04 centsper lb on Friday January 29, down from $92.70/9.27 midway...
Although supply tightness was supportive for copper prices, smelters profits at the same time were put under pressure. Treatment and Refining Charges (TC/RCs) are the fees paid to smelters by mines for converting copper concentrate to copper cathode and key revenue source for smelters. Falling TC...
Copper (Cu) can have either a +1 or a +2 charge in its ionic state. As a transition metal, copper exhibits variable valency and can form ions with partially filled d orbitals. A neutral copper atom ha.. How to Make CuSO4: A Simple Guide to Producing Copper (II) SulphateHave you ...
Capstone Copper Corp. (“Capstone” or the “Company”) (TSX: CS) (ASX: CSC) today reported financial results for the three months and quarter ended March 31, 20...
TCRCs (treatment and refining charges) fall when tight concentrate supplies squeeze smelters’ profit margins. A recent BMO Metals Brief states “Spot TCRCs are now at the lowest level since March.” Global miners have reached agreements with Chinese smelters for lower TCRCs, the first drop in...
The U.S. president has also pledged a broader set of tariffs to match the rates that the U.S. government says other countries charge, as well as specific tariffs on autos, computer chips and pharmaceutical drugs. Trump's broader tariffs on as much as $3 trillion in imports...
no additional heat need be supplied the charge in the refining furnaces B and C as the deoxidation reactions are sufficiently exothermic to maintain the metal in the desired molten state. If necessary, however, heat may be supplied by the combustion of dry coke or pre-ignited charcoal through ...
