IMPROVEMENTS IN AND RELATING TO THE MANUFACTURE OF SALT FROM BRINE
Year: 1884

page_text: 'I GEORGE STEWARD HAZLEHURST of Southlands, Rhyl in the County of Denbigh,
North Wales Gentleman do hereby declare the nature of my said Invention for
IMPROVEMENTS IN AND RELATING TO THE MANUFACTURE OF SALT FROM BRINE
to be as follows:-
My Invention has for its object certain improvements in the manufacture of
common salt from brine, and consists in precipitating the salt from the brine by
mixing the brine with a salt such as chloride of calcium, or any other salt that is
more soluble than common salt. The solution of the precipitant being always of
greater specific gravity than the brine causes the salt to be precipitated from the
brine.
If the precipitant be hot and strong, salt of a fine quality is instantly precipitated
from the brine.
If the precipitant be cold and of specific gravity only slightly greater than the
brine, very large crystals are slowly formed,
When the salt has been precipitated from the brine I remove the liquor and
reconcentrate it up to the required strength. It can then be used over again in
precipitating the salt from a fresh quantity of brine.
In order to remove all traces of the precipitant from the salt, it is first drained
and then thoroughly washed with brine.
By my Invention salt can be precipitated from brine, either as fine as the best
table salt, or in very large crystals, the intermediate qualities may also be obtained
the qualities depending on the strength and temperature of the precipitant.
Dated this Eighth dose of Da 1901.

page_text: I GEORGE STEWARD HAZLEHURST of Southlands, Rhyl, in the County of Denbigh,
North Wales Gentleman do hereby declare the nature of my said Invention for
IMPROVEMENTS IN AND RELATING TO THE MANUFACTURE OF SALT FROM BRINE
and in what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement:-
My Invention has for its object certain improvements in the manufacture of
common salt from brine and consists in precipitating the salt from the brine by
mixing the brine with a salt such as chloride of calcium, or any other innocuous
salt that is more soluble than common salt. The solution of the precipitant being
always of greater specific gravity than the brine, causes the salt to be precipitated
from the brine.
If the precipitant be hot and strong salt of a fine quality is instantly precipitated
from the brine.
If the precipitant be cold and of specific gravity only slightly greater than the
brine very large crystals are slowly formed. In forming these large crystals care
must be taken that the solutions be mixed without the least disturbance.
When the salt has been precipitated from the brine I remove the liquor and
reconcentrate it up to the required strength. It can then be used over again in
precipitating the salt from a fresh quantity of brine.
In order to remove all traces of the precipitant from the salt, it is first drained
and then thoroughly washed with brine.
By my Invention salt can be precipitated from brine, either as fine as the best
table salt, or in very large crystals; the intermediate qualities may also be obtained
the qualities depending on the strength and temperature of the precipitant.
Having now particularly described and ascertained the nature of my said
Invention and in what manner the same is to be performed, I declare that what
I claim is:
In the manufacture of salt from brine, precipitating the salt from the brine,
by mixing such brine with chloride of calcium, or equivalent innocuous salt,
substantially as set forth.
