Production of liquid magnesium

Claim 1

IN A METHOD OF PRODUCING MAGENSIUM BY THE THERMAL REDUCTION OF MAGNESIUM ORES BY NON GASFORMING SOLID REDUCING AGENTS, THE STEPS OF FORMING FINELY DIVIDED PARTICULATED INTIMATE MIXTURE OF SAID ORE AND REDUCING AGENT, INTRODUCING SAID MIXTURE INTO A VERTICAL ELONGATED REACTION CHAMBER COMPRISING THREE SUPERIMPOSED VERTICAL ZONES, HEATING SAID MIXTURE TO DEGAS AND DRY IT AND SIMULTANEOUSLY FEEDING THE SAME BY GRAVITY TO FORM A SELF-PACKED SUBSTANTIALLY GAS IMPERVIOUS ENCLOSED COLUMN OF SAID MIXTURE IN THE FIRST ZONE, ALLOWING SAID GAS IMPERVIOUS COLUMN TO DESCEND BY GRAVITY FROM SAID FIRST ZONE INTO A REDUCTION ZONE, REDUCING THE ORE IN SAID REDUCTION ZONE BY HEATING TO REACTION TEMPERATURE TO VAPORIZE THE RESULTING MAGNESIUM, WITHDRAWING THE MAGNESIUM VAPORS FROM SAID REDUCTION ZONE SUBSTANTIALLY LATERALLY INTO A CONDENSATION CHAMBER, ALLOWING THE SPENT SOLID REACTION MATERIALS TO FORM BY GRAVITY A SELF-PACKED GAS-IMPERVIOUS ENCLOSED COLUMN IN THE THIRD ZONE BENEATH SAID REDUCTION ZONE, SAID COLUMNS OF RAW AND SPENT MATERIALS IN
