Improvements in Apparatus for washing ores,
We MYLES KENNEDY of the Roanhead Hæmatite Mines, Offices, Market Street
Ulverston in the County of Lancaster, Mine Proprietor, and GEORGE GREEN, of
Aberystwyth, in the County of Cardigan, Engineer do hereby declare the nature of
this Invention to be as follows that is to say :-
This Invention comprises an improved combination and arrangement of apparatus
specially designed for washing iron ores but also advantageously applicable for
treating other ores.
In carrying out the Invention the ores with water are passed through a primary
cylinder made of wrought iron and placed in a position slightly inclined from the
horizontal. This primary cylinder which is situated at the highest part of the
apparatus is provided with an internal screw made of angle iron and which is
perforated to allow water to pass downwards and out over a flange at the lower end
of the cylinder, this water carrying away loosened clay, whilst the screw causes the
ore to travel upwards. The rough ore ultimately passes from the higher end of the
primary cylinder down upon a picking and shaking table, which delivers it into a
waggon. In the primary cylinder at the lower end there are a number of spikes to
loosen the clay from the ironstone and also to carry up and turn over the materials.
A length of three feet at the higher end of the primary cylinder is perforated to allow
the finer ore to pass through to a trough and on to a first trommel which is of a finer
mesh than the perforations at the end of the primary cylinder. This first trommel
delivers into the waggon the washed ore which will not go through the mesh, whilst
the finer particles which pass through are led by a launder to a second trommel
having a still finer mesh. The material which does not pass through the mesh of the
second trommel is delivered to a first jigger which separates the quartz and siliceous
matters from the ore.

page_text: The material that passes through the mesh of the second trommel is conducted to a
third trommel, and the material not passing through the mesh of this third trommel is
. treated in a second jigger. All the fine stuff which passes through the mesh of the
third trommel is conveyed by a launder to a first water-current classifier which
deposits the roughest portions on a propeller buddle on which they are scrubbed by
wire brushes and oblique scrapers and in which the ore is washed and cleaned. The
water and materials which go over the first classifier are led to a second classifier
which delivers the material to a second propeller buddle.
The materials from the jiggers and buddles are led to an elevator which raises them
and delivers them into the waggon. The number of the jiggers, classifiers, and
buddles may be varied if found desirable in different cases.

We, MYLES KENNEDY, of the Roanhead Hæmatite Mines, Offices Market Street,
Ulverston, in the County of Lancaster, Mine Proprietor, and GEORGE GREEN, Of
Aberystwith, in the County of Cardigan, Engineer, 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, that is to say :-
This Invention comprises an improved combination and arrangement of apparatus
specially designed for washing iron ores, but also advantageously applicable for
treating other ores.
The said improved combination is shown on an accompanying sheet of explanatory
drawings, of which figure, 1, is a plan, figure, 2, a sectional end elevation, and
figure, 3, a side elevation. The constructive details of each separate piece of apparatus
or machine being well known do not require to be particularly described; and the
machines are shown in the drawings diagrammatically and simply as forming
elements of the improved combination and arrangement.
In carrying out the Invention the ores with water are passed through a primary
cylinder, A, made of wrought iron and placed in a position slightly inclined from the
horizontal. This primary cylinder, A, which is situated at the highest part of the
apparatus is provided with an internal screw made of angle iron, and which is
perforated to allow water to pass downwards and out over a flange at the lower end of
the cylinder, this water carrying away loosened clay; whilst the screw causes the
ore to travel upwards. The rough ore ultimately passes from the higher end of the
primary cylinder, A, down upon a picking and shaking table, B, which delivers it
into a waggon, C. In the primary cylinder, A, at the lower end there are a number
of spikes to loosen the clay from the ironstone and also to carry up and turn over
the materials. A length of three feet at the higher end of the primary cylinder, A,
is perforated to allow the finer ore to pass through to a trough, D, and on to a first
trommel, E, which is of a finer mesh than the perforations at the end of the primary
cylinder, A. This first trommel, E, delivers into the waggon, C, the washed ore
which will not go through the mesh, whilst the finer particles which pass through are
caught in a trough, F, and led by a launder, G, to a second trommel, H, having a
still finer mesh. The material which does not pass through the mesh of the second
trommel, H, is delivered to a first jigger, J, which separates the quartz and siliceous
matters from the ore.
The material that passes through the mesh of the second trommel, H, is conducted
to a third trommel, I, and the material not passing through the mesh of this third
trommel, L, is treated in a second jigger, M. All the fine stuff which passes through
the mesh of the third trommel, L, is conveyed by launders, N, to a first water-current
classifier, O, which deposits the roughest portions on a propeller buddle, P, on which
they are scrubbed by wire brushes, and oblique scrapers, and in which the ore is

page_text: washed and cleaned. The water and materials which go over the first classifier, O,
are led to a second classifier, Q, which delivers the material to a second propeller
buddle, R.
The materials from the jiggers and buddles are led to an elevator, S, which raises
them and delivers them into the waggon, C. The number of the jiggers, classifiers,
and buddles may be varied if found desirable, in different cases.
The driving power for the various machines is derived from a steam engine or
other convenient motor, which is not shown, being transmitted by a belt, T, to a
pulley on a shaft, U, which has on it bevil gear (not shown) for turning the primary
cylinder, A; and which by pulleys and a belt, V, drives a second shaft, W. This
second shaft, W, has on it various pulleys for belts, which are indicated by dotted
lines, for transmitting power to the various machines."
Having now particularly described and ascertained the nature of the said
Invention and in what manner the same is to be performed, we declare that what we
claim is
Combining and arranging apparatus for washing ores substantially in the improved
manner hereinbefore described and shown in the accompanying drawings.
