Magnesium - for reuse in zirconium sponge production (market for)

The activity generating the emissions is market for magnesium, for reuse in zirconium sponge production. The reference product is magnesium, for reuse in zirconium sponge production. This product represents magnesium produced by the electrolysis of magnesium chloride according to the following reaction: MgCl2 -> Mg + Cl2. The magnesium chloride is obtained during the production of zirconium sponge using the Kroll process, in the reduction and distillation step, described by the following reaction: ZrCl4 + 2Mg -> Zr + 2MgCl2. Through the electrolysis of magnesium chloride, part of the Mg and Cl is recovered and then reused in the Kroll process. This product should not be used in any other context. The reference product amount is 1. The cut-off classification is allocatable product. The activity type is ordinary market activity.
