Description
the solution in a Arts Pa rnn'r PROCESS FOR EXTRACTION OF MERCURY FROM ITS ORES AND OTHER MATERIALS.
No Drawing.
To all whom it may concern:
Be it known that I, EDWIN BRYANT THORNHILL, a citizen of the United States of America, and resident of Gray Summit, in the county of Franklin, State of Missouri, in the United States of America, have invented certain new and useful Improvements in Processes for Extraction of Mercury from its Ores and other Materials, of which the -lt'o-llowing is a specification.
The invention relates to a process for the extraction of mercury from its ores or other materials, and the objects of the invention are to exercise economy in regard to the costs incidental to the production of mercury and to provide an efficient method that will insure a maximum quantity of mercury from a given quantity of the material from which it is extracted, and it consists essentially of the steps in or about the order named, together with the substances used, all being set forth in detail hereinafter and pointed out in the claims for novelty following this description. This method is based on the allinity of mercury sulfid to a solution containing an alkali sulfid and an alkali hydroxid, so that when the ore or other ma terial containing mercury sulfid is treated with this solution, the mercury will leave the original material and go with the solution. The preferable constituents of the solution are sulfid of sodium and hydroxid of sodium.
The solvent, consisting of the solution carrying the mercury that has been ext acted, is brought into contact with a metallic substance, aluminum or chromium, or any other metal that is soluble in an alkali hydroxid and does not form the sulfid in the wet way, so that the mercury contained in said solution will be precipitated as finely divided metallic mercury and the metallic substance used as precipitant will go into the solution. The preferable manner of carrying out the withdrawal of the mercury from the solution is to add the metallic precipitant in a finely divided state to the solution during the violent agitation of the latter, thus thoroughly separating all of the mercury from the solution. The mercury withdrawn from finely divided state is rubbed or otherwise treated to bring the Specification of Letters Patent.

Precipitation and regeneration:
\Vhat I claim is:
1. The herein described process for the extraction of mercury from its ores and other nuirterials consisting in first treating the ore or other material with an alkali sulfid and an alkali hydroxid in solution and carrying the mercury with said solution, and withdrawing said mercury i'rom said solution by the addition of a precipitant to the latter.
2. The herein described process -for the extraction of mercury from its ores and other materials consisting in treating the ore or other material with a solution of alkali sullid and alkali hydroxid, and adding to the solution a metallic substance as a precipitant, and thereby separating the merucry from said solution.
3. The herein described process for the extraction of mercury from its ores or other materials consisting in treating the ore or other materials with a solution composed of sulfid of sodium and hydroxid of sodium, and thereby carrying the mercury into the solution and adding aluminum to said solution as a precipitant, and thereby separating the mercury from said solution.
4. The herein described process for the extraction of mercury from its ores and other materials consisting in treatingthe ore or other material with a solution composed of an alkali sulfid and an alkali hydroxid, then adding a metallic substance to the solution Signed at the city of Toronto, this 2d day and separating the mercury from the soluof December, 1913.
