From the European Union by yourself, this will likely introduce nearly 13,000 metric a lot of further mercury to the marketplace (equal to some six-twelve many years of Main mercury manufacturing). In response to this probable glut of mercury, Euro Chlor, which represents the eu chlor-alkali industry, has signed a contractual agreement with Minas de Almadén in Spain.
