Starting from either open-pit or underground mining and using a different relevant treatment method for oxide or sulphide copper mineral (ore). Having a quick look now at how porphyry ores …
There are three main steps in designing a good crushing plant: process design, equipment selection, and layout. ... it is prudent to have testwork conducted to establish ore flow properties, which will influence design parameters. At virtually all mines, ore characteristics change over time, and it can be costly to "design in" ...
Mineral processing plants require a storage buffer to bridge differences in production rates between mining and processing. Where coarse ores are processed, such as coal or hard rock, this buffer may be an ore stockpile or silo. For wet-mining processes, e.g. dredging or hydraulic mining, or where fine ores are slurried close to
