SHANGHAI, Mar 9 (SMM) - The domestic refined nickel output in March is expected to increase 1.16% on the month and 38.89% on the year to 17,500 mt. The domestic refined nickel output in March is expected to increase only slightly compared with that in February as most new production lines have been fully put into production. Many companies still have expansion plans in the second quarter, and thus China's refined nickel output is expected to hit a new high in the second quarter.
