  • AN INTRODUCTION TO COPPER EXTRACTION Murdoch University

    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 the

  • Copper Mining and Processing: Processing Copper Ores

    After the copper ore is crushed, liquid is added to make it a slurry. The slurry is a mix of valuable copper ore minerals and “worthless” rock, called gangue (pronounced “gang”). The slurry is placed in a tank and a process called froth floatation is used to separate the copper minerals from the gangue. Chemical reagents called “collectors” are added to the slurry and bind to the copper particles, making them

    The mine currently produces 60 000 tonnes per year of high purity copper cathodes. Procedure. The benches are drilled and loaded with explosives that have a powder factor around 160g / t. The ore is then hauled and dumped into the primary crusher. The primary crusher is a gyratory crusher that reduces the size to 95% below 5 inches.
