Ivanhoe Mines begins new era of commercial 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.
What are environmental regulations on mining activities
New mine developments are now required to have operation and closure plans that define how a specific site will be reclaimed upon cessation of mining. This attention to the full life-cycle of a mining site prevents negative environmental impacts. Federal laws that regulate mining.
