Abstract

Magnesium is recovered from a superheated gaseous mixture comprising essentially carbon monoxide gas and magnesium vapor by shock-cooling the vaporous composi­ tion with a spray of liquid magnesium chloride flux composi­ tion preferably heated to a temperature near its vaporization temperature. The liquid magnesium chloride flux composi­ tion is instantly vaporized with a large absorption of high temperature heat and the vaporous mixture is thereby cooled to a temperature somewhat about the vaporization temperature of magnesium. The resultant vaporous magne­ sium is recovered by condensation to produce a molten magnesium product.
