         9 . The method of  claim 1 , wherein said furnace system is comprised of a first furnace configured to receive the prepared ore comprising a plurality of the element oxides and receiving a first feed chemical including hydrogen for stripping a substantial portion of the oxygen from the oxides for outputting a plurality of different elements; and wherein said furnace system is also comprised of a second furnace for receiving the plurality of different elements and receiving a second feed chemical for outputting the plurality of different chemical compounds that are chemical salts of the various elements to the electrowinning system. 
     
     
         10 . The smelting system of  claim 1 , wherein the prepared ore is input into the furnace system as a liquefied feed stock. 
     
     
         11 . A method of using a smelting system comprising a furnace system and an electrowinning system for extracting elements from ore, comprising the steps of:
 obtaining ore comprising a plurality of different elements and/or comprising a plurality of different naturally occurring element compounds;   preparing the ore for transportation and input into the smelting system;   inputting at least one feed chemical into the furnace system;   inputting the prepared ore into the furnace system;   heating the ore and the at least one feed chemical in the furnace system to convert the plurality of different elements and/or the plurality of naturally occurring element compounds in the inputted ore into a corresponding plurality of different chemical compounds utilizing the input feed chemical;   outputting the different chemical compounds from said furnace system into the electrowinning system comprising a plurality of electrowinning tanks provided in series, wherein said electrowinning tanks are configured to extract the different elements from respective chemical compounds output by the furnace;   operating each one of the electrowinning tanks to extract the different elements; and   outputting the different elements separate from each other from respective outputs of the electrowinning tanks.   
     
     
         12 . The method of  claim 11 , wherein said electrowinning system releases the feed chemical or a compound thereof for recirculation in the smelting system.
