A study was therefore undertaken using life cycle assessment methodology to examine various alternative processing routes for extracting metal from low grade ores (down to 0.1% metal), particularly those of copper and nickel, in terms of their life cycle-based energy consumption (embodied energy) and greenhouse gas emissions.

Nickel processing | Britannica.com

Extraction and refining. The extraction of nickel from ore follows much the same route as copper, and indeed, in a number of cases, similar processes and equipment are used. The major differences in equipment are the use of higher-temperature refractories and the increased cooling required to accommodate the higher operating temperatures in nickel production.

Transforming Copper Ore into a Refined Product - feeco.com

copper products. Once mined, higher quality sulphide ores are processed into a more concentrated form, referred to as copper concentrates. This ore type is then refined via pyrometallurgy. Low-grade sulphide ores and oxide ores are processed via heap leaching and typically refined via the increasingly popular hydrometallurgical approach - SX-EW.
