  • AN INTRODUCTION TO COPPER EXTRACTION

    The copper extraction process begins at an open cut mine where Copper Ore is blasted and removed via Excavators and Tip Trucks The ore is fed to a Crusher where it is broken down to a specified maximum size and passed through to a conveyor When the crushed ore falls onto theCopper has been an essential material to man since prehistoric times In fact, one of the major "ages" or stages of human history is named for a copper alloy, bronze Copper and it's many alloys have played an important role inCopper History: Copper through the AgesHistory of copper Copper has been an essential material to man since prehistoric times In fact, one of the major 'ages' or stages of human history is named after a copper alloy: bronze Copper was the first metal used by man in any quantityHistory of Copper | Home | Website | Makin
