Definitions
- An object of the present invention is to imfprove the overall economic efllciency of this method.
- a more specific object is to obtain a maximum recovery of magnesium in the calcine ered.
- each retort While the retort remain within the furnace under operating temperatures of 1100 to 1200 C. the condenser end of each retort is opened to the air for removal of the condensed metal, discharge of the residue and recharging.
- the retorts may be 6 to 12 inches in diameter, preferably 8 'or 10 inches, and are charged and discharged in groups in an operating cycle which may vary from say 6 to 12 hours.
- the hot retorts are charged with briquettes, evacuated to remove steam, occluded and adsorbed gase and the charge is maintained under avery low pressure.
- Silicon vapour is evolved from the ferrosilicon and this vapour reduces the magnesia to magnesium which is volatilized and condensed.
- the exposed ends of the retorts are opened to the air and discharged.
- a method of producing metallic magnesium which comprises calcining dolomite; and heating under reducing conditions thefcaicined dolomite with ierrosilicon in proportions to provide aratio of calcine to silicon between I to 0.160 and 1'toO.189.
- a method of recovering magnesium'from' magnesia-containing material which comprises the step of heating under reducing conditions the magnesia-containing material with ierrosilicon proportions to provide substantially 15% silicon in excess oi the theoretical amount required for the reaction.
- a method of recovering magnesium from magnesia-containing material by thermal reduction which comprises heating under reducing conditions said material containing one mole of VICTOR'WHITON. 4 HUGH MQLAURIN'WELD.
