A Guide To Copper Production and Manufacturing Methods
Refining. The first step in the copper manufacturing process is refining. Copper ore that is mined from the earth is typically mixed with other minerals, such as iron, sulfur, and silica. This mixture is then heated in a furnace to a temperature of 2,000 degrees Fahrenheit. This process removes most of the impurities from the copper ore and ...

Copper Processing | Multotec
Extraction of copper from ore begins with pre-treatment. Due to the decreasing concentration of copper in ores, this is an important step to decrease the volume of material and to increase the grade of copper in the ore. Most copper ores will only contain a small percentage of copper mineral, with the average grade being below 0.6% copper.
