The KDD process, specifically data mining techniques, is used to characteristically discover knowledge from data (Zhu & Davidson, 2007). The data mining process extracts knowledge from an existing data set and transforms it into a human-understandable structure for further use (Witten, Frank, & Hall, 2011).
The copper production process involves several steps. Mining extracts the raw copper ore from the earth. Crushing reduces the ore's size for easier processing. Concentration separates the copper-bearing minerals from waste rock. Smelting melts the concentrated ore to extract the copper. Refining purifies the copper to a high level of purity.
