Sulfide ores thereby go through a froth flotation process to gain concentrates containing ≈ 30% Cu, converting concentrates to main products offered by copper mining companies (Glöser, Soulier ...
In some cases, the concentrate is submitted to an additional processing step to extract a by-product (e.g. molybdenum sulfide). Finally, the copper concentrate is dried ready for transportation to the next step (smelting). The copper concentrate production process does not involve any chemical modification of the original ore body. 2.
Sphalerite/marmatite existed in copper sulfide concentrate as impurity may lead to severe damage of the smelting equipment, and cause the waste of copper and Zn resources, it will also decrease of the sale price of copper concentrates. Therefore, the deep separation of zinc from zinc bearing copper sulfide concentrate is of great …
Following a one-month consultation, Fastmarkets will proceed to revise the outlier detection method used in the calculation of its copper concentrate TC/RC index to reflect spot market changes. Changes will take effect on Friday June 4. The prices involved are: -CU-0287 Copper concentrates TC index, cif Asia Pacific, $/dmtu
A copper concentrator is milling 15,000 tons/day of a chalcopyrite ore assaying 1.15% copper. The concentrate and tailings produced average 32.7% and 0.18% copper, respectively. I let you do the math! Three product (bi-metallic) formulas

The spread between Asia origin, blended copper concentrates and standard clean copper concentrates narrowed from $10/mt TC in September to $2-$3/mt TC Oct. 31. Meanwhile, a number of Chinese smelters have also sought to increase concentrate inventory levels, thanks to higher sulfuric acid prices and copper cathode premiums …
The motivation of this paper is to identify the effect of treatment charge (TC) on LME (London Metal Exchange) copper prices. It is a fundamental variable as a supply side factor, because it is related to the smelting process and reflects the level of concentrates market tightness. To examine this question carefully, the regression model …
The purpose of smelting is to enrich most of the copper in the copper concentrate in the matte phase. The gangue, oxides and impurity elements were combined in the slag phase to completely separate the copper matte in the slag phase. In this paper, a mathematical model based on the optimization of copper concentrate cost and the …

TC/RCs are discounts paid to smelters for turning copper concentrate into refined metal. Typically, the fees drop amid tight supply and increase in a well-supplied market. Most miners and smelters tend to follow an annually agreed benchmark number for their long-term contracts, which is set during supply negotiations between major Chinese …
The delayed restart date for Dongying Nonferrous' second copper production line has also added uncertainty to copper concentrate demand. The second production line with a copper production capacity of 280,000 mt/year had initially been due to restart in October, but the dateline had still yet to be confirmed as of Oct. 4, market sources said.
