From the eu Union by itself, this might introduce around thirteen,000 metric lots of more mercury to the industry (equivalent to some six-12 years of Principal mercury output). In reaction to this probable glut of mercury, Euro Chlor, which signifies the European chlor-alkali business, has signed a contractual arrangement with Minas de Almadén in Spain.
