Base metals, excluding copper, prolonged their slump on Wednesday. The commodity group came under persistent pressure after the IMF lowered its global growth forecast. However, unexpected increase in Italian, French and Swedish industrial production last month restricted the downswing of industrial metals.
Aluminum was the top-loser after the world's largest aluminum producer, Alcoa, cut its global demand growth forecast from 7% to 6%, citing a slowdown in China.
Copper was the only gainer despite weak China's demand and heavy pressure from global growth concerns.
Nickel slid as global steel sector remained weak. Moreover, sluggish demand from China depressed the metal further.
Zinc retreated on continuous supply glut and bleak demand prospects amid global economic uncertainty.
