[Claims 8 and 9 struck out.] (10.) An ore-furnace comprising, in combination, a plurality of vertical combustion-chambers each containing baffles forming a zigzag course through it for the products of combustion, a vertical exhaust-chamber for each combustion-chamber, separated therefrom by spaced walls containing numerous ports throughout their height, and forming between them an ore-channel provided with a feed-inlet at its upper end, a discharging-apparatus in the bottom of each ore-channel, and an exhaust-flue at the bases of and common to all said exhaust-chambers and having valve-controlled communication therewith.
