With prices of iron ore jumping from a little above 50 dollars to $200 per metric ton between 2006 and 2007 and now back to alittle above $50 in November 2008, mining companies around the world are pulling back according to Thomson Reuters. China's building boom is seeing a big slumo with new floor space up 30%in 2007 now down close to 40% from peak according to data from Macquarie Securities. And the Australian dollar up almost 30% in 2007 is now down about 50% from peak. The last time the mining companies saw such a slump was after the Asian financial crisis in 1997 and the US recession of 2001, with metals coming back only after Chinese demand kicked in in 2003. This affects mining in Africa which was seeing boom times in places like S. Africa where there were electricity shortages because of huge demand from mining.
