GEORGE L. COLLORD, OF PITTSBURGH, PENNSYLVANIA.
TREATING ORES No Drawing.
To all 10710122 it may concern:
Be it known that I, GEORGE L. CoLLoRD,
ments in Treating Ores, of which improvements the following is specification.
It is a peculiarity of some ores found in certain parts of the Mesaba region and also in. other parts of the country that they contain a high percentage of moisture and are so lean that nearly all the moisture must be removed to raise the contained. ore to a commercially workable percentage,'i. e.,'
while being dried, the oil will form a protective coating on all the particles of ore and that when so coated, the percentages of moisture can be reduced to or below three per cent. (3%) without the ore being disintegrated in the drying.
In lieu of applying the tar oroil prior to Specification of Letters Patent.
Patented June 15,1920.
Application filed May a, 1919. Serial No. 296,031.
or while the moisture is being reduced to the desired percentage, as described and clalmed in an application, Serial Number 296030, filed of even date herewith, the ore may be subjected to the drying operation 1n any suitable form or construction of drier, and after the moisture has been reduced to the desired percentage, 6. g., to three or two and one half.(3 or 2 )per cent., the tar or oil is mixed with the dried ore. 1t has been found, however, that as there is practicaly no moisture present to facilitate or promote the spreading of the oil or tar over the surfaces of the particles, a larger percentageof oil than that required for the method described in the application above refered to, must be employed, as for example, eight to ten per cent. more or less. It has been found that by the addition of the oleaginousmaterial, the particles of dust will collect and adhere together forming small grains and entirely free from dust.
I claim herein as my invention:
The method herein described of treating moist ore, which consists in reducing the percentage of moisture in the ore, and mixing with the ore thus treatedan oleaginous material adapted to cause an agglomeration of the fine particles of the ore.
In testimony whereof, I have hereunto set my hand.
ono. L. COLL-0RD.
