In 2012, the refinery posted a loss of RON16.4 million.
Alum Tulcea said its sales slid 5% to RON517.3 million in 2013, from RON544.9 million in the previous year.
Alum is Romania’s sole alumina refinery. The bulk of its output goes to aluminum smelter Alro Slatina (ALR.RO), which is 84%-owned by Vimetco.
In March, Alro announced plans to shut down some of its units because of mounting costs with the electricity bills.
