Combination Crusher

Combination Crusher

The combination crusher is a new generation high efficiency crushing machine designed and researched by integrating the domestic and foreign crusher technology with the same kinds and optimizing the main technical parameters.

process of formation of copper ore

Most nonrecycled supplies come from porphyry copper deposits (PCDs), which form whenhot,metal-bearing fluids percolate up through Earth’s crust. But while geologists have long recognized — and exploited — PCDs, two new studies suggest they may need to rethink how these deposits form We are a professional mining machinery manufacturer, the main equipment including: jaw crusher, cone crusher and other sandstone equipment;Ball mill, flotation machine, concentrator and other beneficiation equipment; Powder Grinding Plant, rotary dryer, you can click the button to consult us.

    Processes of Ore Formation. Current theories of thegenesis of ore depositcan bedivided into internal (endogene) and external (exogene) or surface processes. It must be understood that more than one mechanism may be responsible for the formation of an ore body.
