  3. Mining Requirement For Copper

mining requirement for copper

22 hours ago As of 25 May, 5% to 6% copper ore is being conveyed directly from Kakulas underground mining operations to the run-of-mine stockpile and the concentrator. Based on extensive testwork, the concentrator is expected to produce a very high-grade, clean concentrate grading approximately 57% copper, with extremely low arsenic levels.

ASSESSING GLOBAL LAND REQUIREMENT FOR SURFACE COPPER MINING

In this work, a new methodical approach for estimating land requirement for surface copper mining operations is introduced. For the reference year 1998 facts and figures concerning global land requirement for surface copper mining operations are presented. The work closes with a short discussion and gives an outlook to forthcoming research.
