FRANKLIN OSGOOD, OF NEW YORK, N. Y.
IMPROVEMENT IN THE MANUFACTURE OF PIGMENTS CONTAINING ZINCAND LEAD.
Specification forming part of Letters Patent No. 137,474, dated Aplil 1, 1873; application filed March 21, 1873.
To all whom it may concern:
Be it known that I, FRANKLIN Osooon, of the city, county, and State of New York, have invented a new and useful Improvement in the Manufacture of Pigments containing Zinc and Lead; and I do hereby declare the following to be a full and exact description of the same.
Heretofore pigments containing zinc and lead have been manufactured in two ways: First, by a mechanical mixture of materials known as oxide of zinc and the white lead of commerce; second, by treatment of ores of zinc containing lead, or ores of lead containing zinc, by a fire process in a furnace, whereby a greater or less proportion of the lead was carried over in a vaporized form and combined with the oxides of zinc. This species of pigment has been termed in trade zinc-lead; and for its manufacture it has been customary to use solely the sulphurets of zinc containing lead found in mines and known as zinc-blend, black-jack, or other local or mineralogic term.
The difficulties of this operation have been the irregular proportion of lead in the ore, and the danger in the roasting of forming salts which were not oxidizable except at a heat higher than would flux the metal lead. From these causes the product was variable in quality, and the yield in quantity. Further, it is well known that large quantities of zinc metal are used in the process of galvanizing and other manufactures of the arts, and that from these processes and manufactures is resultant large amounts of dross and skimmings, which have heretofore been, in a great measure, a loss to the manufacturer, and that many attempts have been made to utilize these said skimmings or dross in the manufacture of pigments without producing a perfectly oxidized mate, rial, or one fully recognized as marketable.
Therefore, having made a pigment containin g zinc and lead by an entirely new process, and having succeeded in utilizing these skimmings or dross, and making therefrom a thoroughly oxidized material containing zinc and lead, and which is fully equal or superior to any zinc-lead ever before made, I will now proceed to describe my method of carrying the same into effect.
I take any of the known ores of zinc and roast the same so as to separate any acid, whether they be sulphurets, sulphates, carbonates, or chlorides; then introduce them into a suitable furnace, such as a reverberatory, that known as the Wetherell or other form answering my purpose, mixing with them the usual quantity of coal-dust; or, by preference, I take the zinc dross or skimmin gs, if the latter be known as ammoniacal, then first depriving them of all trace of such alkali; then I mix with coal and introduce into the furnace in the same manner as with the roasted ore. In another furnace I charge, in a similar manner, ores of lead or lead dross, or a salt of lead, mixing in coal in like manner; or, if preferred, I mix these metallic materials and the coal allvin one furnace. In either case, if fire has not already been kindled it is now applied to a greater or less degree. As the heat rises the vaporized metals pass upward and are drawn through flues by an exhaust. The mixed vapors of lead and zinc unite and form a combination,which, being condensedin chambers or bags in chambers adapted for that purpose, forms the material which is known to the trade as zinc-lead.
It is seen that in this process no particular form of furnace is required so long as the vapors of the two metals are formed; neither is it essential that the lead and zinc substances should be mixed in the same furnace; but itis positively necessary that their vapors should come together under the influence of heat and air; hence it is seen that the material Iproduce is not a new one, except in its superior quality, and a part of the materials from which it is produced have never been heretofore used for the purpose.
Having thus described my invention, what I claim, and desire to secure by Letters Patout is- I l. The process herein described for producing zinc-lead, the same consisting in passing the vapors of zinc and lead produced by heating the above-mentioned compounds through a flue by means of a pressure of air-blast, as set forth.
2. The process of producing zinc-lead by the mixture of an ore and a metal, or the dross of ameta-l, in a furnace, substantially in the manner described, so that when vaporized by heat inoniaeal skimmings, for the purpose of comthey will pass over through flues into chambining the same with lead'or ores for the probers and condense into a material known as duction of the pigment known as zinc-lead.
zine-lead, having formed a complete union at FRANKLIN OSGOOD. some point of their passage. Witnesses:
3. The method described for the utilization HENRY E. OOLTON,
of dross or skimmings of zinc known as mn- CLARENCE GARY.
