stages of copper ore process
8.2: Mining and Ore Processing
But separation of ore minerals is only the preliminary stage of metal refinement, for most metals the second stage involves separating the actual elements within the ore minerals. For example, the most common ore of copper is chalcopyrite (CuFeS 2). The copper must be separated from the iron and sulphur to make copper metal and that …

Copper Production
Copper sulfide ores also contain other metal sulfides such as molybdenite (MoS 2), sphalerite (ZnS), and galena (PbS). Some oxidized copper mineral deposits that have resulted from the oxidation of sulfides are also found. ... In the broadest sense, any metal production process that involves a molten stage is called "smelting."

Extraction of Copper Oxide (I): Purified CuSO4 Solution
Heating and melting are frequently used to extract copper (Cu) from its parent ores [1,2,3,4].Roasting, smelting, and conversion are the three phases of the heating and melting process for primary copper ores [5,6,7,8,9,10,11].Significant amounts of copper are lost as dust in the first and second phases; this dust is referred to as waste …

Our work shows that scheelite geochemistry can be used to trace the mineralizing conditions but the compositions may be significantly modified during the ore-forming process. Thus, detailed textural relationships should be investigated before using scheelite geochemistry to constrain the hydrothermal fluids and ore genesis.

The main raw material is copper sulfide ore, and high-grade copper oxide ore can also be smelted in the pyrometallurgical process. The mining grade of copper sulfide is 0.3–2%, and the average mining grade is approximately 0.81%. The mined ore is crushed and pulverized. Then flotation will separate the copper sulfide concentrate.
