THE METHOD OF SMELTING SULFIDE BEARING RAW MATERIALS INCLUDING FLOTATION CONCENTRATE WHICH COMPRISES, BRINGING TOGETHER SAID RAW MATERIAL IN FINELY DIVIDED FORM AND A CONTROLLED VOLUME OF AIR SOLELY AT A SINGLE POSITION AT THE BEGINNING OF THEIR PATH OF MOVEMENT, REACTING SAID AIR WITH SAID RAW MATERIAL AT THE POSITION WHERE THEY ARE FIRST BROUGHT TOGETHER, CAUSING SAID AIR AND SAID RAW MATERIAL REACTING THEREWITH TO MOVE SMOOTHLY DOWNWARDLY IN A VERTICAL ELONGATED HORIZONTALLY RESTRICTED PATH, WITH CONTINUOUS REDUCTION OF THE PARTIAL PRESSURE OF OXYGEN IN THE AIR WHILE INCREASING THE REACTION VELOCITY THROUGH RISE IN TEMPERATURE IN THE COURSE OF THE MOVEMENT TO PRODUCE AT THE LOWER END OF SAID PATH A MOLTEN CHARGE AND HOT COMBUSTION GASES, DIRECTING SAID COMBUSTION GASES IN A HORIZONTAL PATH AT THE BASE OF SAID VERTICAL PATH, COLLECTING SAID MOLTEN CHARGE BENEATH SAID COMBUSTION GASES AND SAID HORIZONTAL PATH, AND SEPARATING SAID MOLTEN CHARGE INTO LAYERS OF MATTE AND SLAG.
