The raw materials used in the production process are copper-containing dusts, ashes, drosses, shredded materials, sludges, and runback slag with copper contents between 15 and 60%, as well as other alloy scrap, such as brass, bronze, and red bronze with copper contents between 60 and 80%. The materials we use for refining, such as scrap copper, wires, profiles (rods, metal sheets, rails, etc.), and cut-up and sorted electrical cables contain around 80-99% copper. We use high-grade runback scraps from manufacturing semi-finished products directly in the foundry without refining. Alongside these solid raw materials, we also reprocess copper chloride solutions from the electronics industry.
The raw materials listed above contain copper as well as several other metals, such as nickel, zinc, tin, and precious metals. Following initial assessment and sampling, we use the raw materials in the shaft furnace, converter, anode furnace, or smelting furnaces, depending on the type of refining required.
It is important for us to inspect the secondary materials we receive for problematic substances such as mercury, cadmium, or lead, as well as to check for radioactivity. Following these assessments, which were devised by experts, we either reject the secondary materials or approve them for processing.
