Document Type and Number:
WIPO Patent Application WO/2021/121312
Kind Code:
A1
Abstract:
A method for carbothermic smelting of magnesium and co-production of calcium carbide, particularly appropriate for carbothermic smelting of magnesium using a mixture of magnesium oxide and calcium oxide as a raw material, and carbon as a reducing agent. Preparing a mixed powder containing magnesium oxide, calcium oxide and a carbon reducing agent; preparing the mixed powder into a pellet furnace charge, and placing same into a reactor provided with a heat source; configuring an absolute pressure P in the reactor to be in a range of 1000 Pa ≤ P ≤ atmospheric pressure, or to be micro-positive pressure, and a reaction temperature T being in a range of 11lg2P+71lgP+1210°C
