Treatment of Fulverulent and Dust Ores.
We, APOLLON MOEVIUS, Mining Engineer, and SERGIUS KOKIN, Mining
Engineer, of German Street, Kharkov, in the Empire of Russia, do hereby declare
the nature of this invention to be as follows:-
This invention relates to a new compound or improved material for use in
smelting metals. This material is an ore containing coke, which contains an
admixture of say 15-35% of ore of the metal to be smelted. This compound
permits the utilization of fine dust ores which cannot be advantageously treated
by well known methods; moreover the invention presents the following
advantages:
a) It renders more rapid and more easy the operation of smelting metallic ores;
b) It increases the production of the blast-furnace;
c) It effects a considerable economy in fuel; and,
d) It economises the cost of working.
This method may be also applied to lump or broken-ores and generally to any
ore capable of being first reduced to a powder like state for the purpose of being
more intimately mixed with the fuel.
The new ore containing coke may be applied to the treatment in a blast furnace
of iron-ores, as well as other ores, containing any other metal, provided that the
ore be rich enough and should not contain considerable quantities of lime or
magnesia. These ores are mixed by means of ordinary mixing or kneading devices,
such as are used for clay in brick-fields in a ratio of about 15-35% with a fat
coke-coal; said compound is then treated in an ordinary coke-oven provided with
a discharge-device, this operation not differing from the ordinary coking process,
except that it may be of somewhat greater duration. The compact and resistant
coke, obtained by this process, contains the ore in a state almost completely reduced
by the action of the carbon thereby facilitating and rendering more economical
the ulterior process of treatment in the blast furnace. The pulverulent and dust-
ores treated by this method do not descend too rapidly in the furnace, do not
impede the ascending draught of the combustion gases, are not carried away by
the gases in the exhaust-chimney of the furnace do not obstruct the blast-devices
and gas supply nozzles, whereby these devices remain for a longer time in a good
and efficient condition, so that the complicated and difficult operation of cleaning
them is less frequently required.
In respect to the quality of coal, for this improved ore containing coke, it may
be stated that not only any ordinary metallurgical coal may be used, but also any
coal more fat and rich in gas, as smith's coal or gas-coal may be used; this circum-

page_text: stance presenting great economical advantages in localities in which these kinds
of coals are abundant.

An Improved Ore-containing Goke and its Application for the
Treatment of Pulverulent and Dust Ores.
We, APOLLON MOEVIUS, Mining Engineer, and SERGIUS KOKIN, Mining
Engineer, of German Street, Kharkov, in the Empire of Russia, do hereby declare
the nature of this invention and in what manner the same is to be performed, to
be particularly described and ascertained in and by the following statement:-

claim is:-
An improved ore containing coke preferably applicable to the treatment of

consisting of a compound of ore and coal preferably in the proportion of 15-33%
of ore intimately mixed together and coked substantially as and for the purpose
described.
