Increase The Micro Fracturing Copper Ore

Hydraulic fracturing in mining - CSIROpedia

Hydraulic fracturing in mining - CSIROpedia

A fracturing equipment system was designed, built, and delivered to the mine, allowing the mine to continue to use hydraulic fracturing to induce caving. From 1997 through 1999, eight million tonnes of copper-gold ore were induced to cave saving the mine several million dollars compared with conventional blasting methods.

These secondary copper minerals may form rich ore in the upper parts of many deposits, and owing to their characteristic green or blue colour, even small amounts are easily seen in the rocks in which they occur. Copper bearing minerals are commonly found in association with minerals which may contain gold, lead, zinc and silver. Resources
