UNITED STATES PATENT OFFICE.
ROKUSABURO KONDO, OF TOKYO, JAPAN.
SM-ELTING OF S ULFlD ORES- Specification of Letters Patent.
Patented Nov. 20, 1906.
Application filed latch 21 1906. Serial No. 803,749-
To all w/wm it may concern:
Be it known that I, RoKUsABUno Kouno, a subect of the Em eror of Japan, and a resident of No. Badbacho Honjo-ku, Tok 0, Japan, have invented a new and useful mprovement in Smelting ofv Sulfid Ores, of
rectly into the blast-furnace would cause much trouble by choking the furnace, causing irregularity, lessening capacity, requiring more blast-pressure and more coke andproducing much flue-dust. To avoid these evils, it has been customary to mixthese chargingmaterial smalls with clay or with lime as a binding or cementing material, and mold the mixture into bricks, which after being dried were smelted in the blast-furnace; but. the bricks made in this way cannot Withstand breakage and'are very largely broken again into fine particles by handling.
My invention consists in the process of preparing the aforesaid charging-material smalls of sulfid ores for smelting by combining the same with matte (either copper matte or iron matte) as the binding material, and-my invention also includes the brick of said chargingmaterial smalls bound or unitized by said matte as a new article of manufacture.
in the accompanying drawings I have shown an apparatus in which my process may be carried out and my new article of manufacture produced.
Figure 1 isavertical section of said appa ratus. Fig. 2 is a section of the brick removed from the apparatus.
a is a pot or mold, preferabl of cast-steel but which may also be made 0 cast-iron, and which may be two feet in diameter.
1) is the matte-spout on the forehearth of a copper or iron matting-furnace of sul-fid ores.-
c is a hopper containing fine sulfid ore or flue-dust, and h is the spout therefrom. The fine ore or fiue-dust from the s out 7:. and the molten matte from the spout are allowed'to run into the molda simultaneously, so as to-be' thoroughly mixed together therein. If desired mixing may be facilitated by stirfurnace.
ring. When the mixed mass is chilled sufficiently, it is dum ed out of the mold and crushed into suita ble size for charging the The smalls produced by crushing may be returned to the mold again. I use the word matte in its standard signification as meaning an impure metallic product containin sulfur, obtained in the smelting of the suliids ofdifierent metals, especially copper. i
It will be observed that by the use of the apparatus above described the stream of matte from the spout b and the stream of sulfid-ore charging-material smalls from' the spout h are directed'substantially' to the 1 same point at the center of the pot a, so that they practically mingle together as they fall into the pot at this point, and spread outwardly in filling the pot. This mode of operation is very important to the proper formation of the brick, because it causes the inflowing smalls to mix with the inflowing matte at the time when the matte is at its maximum temperature, and therefore in its most liquid condition, and causes the cooling to take place after the two constituents of the brick have been mixed together. The com arative specific gravity of the smalls an the molten matte is such that the particles of the smalls will be floated by the stream'of matte and carried b it until cooled, so as to forman approximate y homogeneous mixture of the two in the com leted brick. I
I am aware 0 Patent No. 784,850, granted March 14, 1905, to Furukawa, covering a smelting-brick composed of a single core of charging-material smalls substantially sur-' terial smalls as a core and the matte as asurrounded by a shell'of matte, and I do not rounding shell, in my brick the char ing-mamatte and sulfid ore charging-material smalls.. 2. The improvement in the art of making smelting-fl)ricllgs1 which consists in causing 1a stream 0 su ore char i -materi-al smal s to mingle with a stream o i molten matte at ROKUSABURO KONDO' approximately the center of a containing ves- Witnesses: v
