Copper concentrates:

Copper concentrate is a product made by processing/enriching copper ore, which usually has a relatively low metal content and is not suitable for direct metallurgical processing. Usually, copper content in concentrate varies from percentages in the teens to several tens of percent, which enables further processing in copper smelters and refineries. The cost of transporting products with a lower copper content (for example copper ore) basically eliminates them from trade in the global market (with certain exceptions), therefore it may be assumed that copper concentrate is the first product of processing copper ore that may be generally traded. As a result of metallurgical processes copper is produced as well as the by-products of processing (mainly precious metals, sulphuric acid, lead etc.).

The main participants of the concentrate markets are mines supplying the product on the market and smelters and refineries, for which the concentrates are materials for production. Trading companies also play a role on this international market, intermediating in the purchase/sale transactions and offering additional services expected by the parties.

Copper concentrates require processing into refined copper, which leads to incurring processing costs and the incomplete recovery of metals in individual production stages. Therefore, the transaction price should have a set of discounts as compared to quoted prices for refined copper. The benchmark of these discounts (for TC/RC) is determined during negotiations with the main producers of concentrates (Freeport McMoRan, Antofagasta) and their customers (mainly Chinese and Japanese smelters and refineries).

Copper cathode (LME):


Copper cathode is used as a starting material for copper rods. Copper cathodes are also used for making alloys like brass, bronze and alloy steel, with applications in defense and construction. Our cathodes meet international quality standards and are registered as LME “A” grade known for its high purity and consistent quality. Ametheus copper cathodes are square-shaped plates of 6mm thickness, with 99.99 per cent copper purity levels which are produced using the Mount ISA electro-refining process.

Copper cathodes meet International Quality Standards such as BS 6017 1981 (1989) and u-Cath-1 / ASTM B-115 (1999) and are registered as A-Grade cathode on London Metal Exchange (LME). Copper cathodes are high-grade, and have the lowest levels of various group and individual impurities.

Copper cathodes are used in the manufacturing of continuous cast copper rods which are further used for the wire, cable and transformer industries. They are also used for the manufacturing of copper tubes for consumer durable goods and other applications in the form of alloys and sheets.

Continuous Cast Rods (CCR)

Our copper continuous cast rods meet all the requirements of international quality standards. Our copper rods are currently used primarily for power and communication cables, house wire, strips for power and distribution transformers, magnet wires, etc. Their excellent surface finish makes them suitable for processing to enameled, coated and plated wires. They are available in diameters of 8, 11, 12.5, 16 and 19mm.
