Reuters reported that Aluminum Corporation of China Limited estimates profits for 2011 will decrease over 50% from the year earlier.

Chalco said that major reasons for the fall in profits were a sharp drop in the price of aluminum in the Q4 caused by the European debt crisis and a hike in the price of electricity which increased production costs.
