TO ALL "WI-IOM IT MAY CONCERN:
Be it known that I, HENRY GOULDING, of Silver City, county of Lyon, Stato of Nevada, have invented certain new and useful Improvements in Furnaces for Roasting Orcs; and I do hereby declare the following description and accompanying drawings are sull'icient to enable any person skilled in the art or science to which it most nearly appertains to make and use my said invention or improvements without further invention or experiment. Y
The nature of my invention is to provide a furnace for roasting orcs containing the precious metals, and consists in placing the ore, pulp, or tailing, in a plastic or wet state, in cylindrical moulds, having vertical pipes or plugs through them, which form tlucs for the heut and llames of the furnace to pass up through, which roasts and dries the ore, rendering it lit for easy amalgamation. The bases of the moulds are provided with plates, either separate or attached to them, and are furnished with lugs with which to raise or lower the moulds, changing their position from top to bottom of the furnace, or transferring them to a cooler placed at one sido of the furnaceV by means of a crane. The object of the cooler is-for the purpose of utilizing the waste heat, and when the lower mould in the furnace becomes sufficiently roasted it is removed by means of the crane into the cooler, and a freshly-filled mould or moulds are placed upon it, so that it may become partially dry before being placed in the furnace. A pipe is placed at the top of the furnace for conducting away the gases and volatile matter from the ore, which passes through a horizontal watcr-tank, which condenscs the volatile parts, and saves the quicksilver, as in ease of working tailings.
To more fully illustrate and describe my invention, reference is had to the accompanyingr drawings and letl ters marked thereon, of which- Figure l is a horizontal section, taken through the line :1:
Figure 2, a front elevation.
Similar letters indicate like parts in each of the figures.
A and B represent the brick-work of my furnace and cooler7 C the iron front, D the hre-door, and E the ash-door. The furnace has a round hole above the fire-grate, of the size of the inner circumference of the cylinders or moulds. The grate-bars are similar to those of any furnace, and Wood, coal, or any good fuel, may
be used. r.lhc moulds or chambersia Z1 are each provided with lugs, c and a', at the top and bottom, for the p11rpose of connecting them together in withdrawing from the furnace Also, the base of eachchamber is furnished with a plate, either separate or attached to the chamber, which is perforated with the holes g g. These holes are provided with plugs, to be withdrawn after the chambers are filled with ore or have become partially dry. If the ore is soft and pulpy by reason of containing much water,'tubes may be employed instead of plugs, and be withdrawn after it has become sufficiently dry to stand. By this means ilues are obtained, so that the heat and flame may pass through them. The inner surface of the chambers may be luted, so as to prevent corrosion or decomposition, but the outer surface, not coming in contact with the gases, need not be luted. The smoke pipe or flue II, at the top of the furnace, is carried down on a plane with the foundation of the furnace, and passes through a watr-tunk, G, for c ondensing'the volatile substance, more especially quickslvcr. At the right of the furnace is constructed a cooler, B, with a door, J, tho'top being covered by a. movable plate. In this cooler are placed the moulds, after the ore has become sufficiently roasted in the furnace, by means of thc .crane K, provided with the necessary chains and pulleys, and attached to a. winch and cross, that may be easily connected to the four lugs on the upper edge of the moulds, The doors I are for thc purpose of closing the furnace, and the upper one should have a flap, m, to allow the crane to swing over the centre of the moulds.
The operation may be described as follows, to wit: Say three moulds or chambers, having beenlled with thc'ore, and so dried as to admit of withdrawing the plugs, are'placed on the plate in the furnace, in which a fire has been kindled, and when the mould next the fire-grate has become sulciently roasted, or brought to a red heat, the thrce'are transferred, by means of the crane, to the cooler, where the lower one, after having'been disengaged, is left, and the other two returned to the furnace, which brings mould No. 2 into more immediate contact with the flame; and to lill ther space occupied by No. 3, a freshlydilled mould is raised to the top, and so on, as festas the lower one has become sufficiently roasted and removed, another one may be placed on the top. The plugs from the freshly-filled ones so placed need not be drawn until the orc has become nearly dry,
or of suicient consistency that the fines will remain entire.
If slum or thin pulp is to be treated, tubes will be found much better than plugs, but they should be withdrawn as soon as the ore around them becomes hard enough to form the flue without their support, as decompo` ition will take place by the action of thc gases coming in contact with the iron. 4
i To facilitate the operation of drying and utilize-the'waste heat, I place a freshly-filled mould upon the top of the one which has been recently removed from the furnace to the cooler. By this means a mould will become nearly or completely dry, so that the plugs or tubes may b e withdrawn before transporting it to the furnace; and as each mould or chamber becomes cool, the ore maybe emptied, and easily disintegrated or slaekened, and ready to be amalgamated.`
I am well aware that ores have been formed into'bricks and dried, after which they are roasted, afterthc manner of burning brick; but great disadvantages must occur -by this mode of treatment, the principal ones of which are, irst, the great expense ot making and drying the brick suiiiciently to lay them up in a kiln for roasting; second, the difficulty of suflicieutly roasting the bricks farthest from the fire Without vitrifying those nearest to it, causing great labor before the ore can be properly prepared again for amalgamation; also, in working tailings, the quicksilver is all lost, and to carry on the briclc process a large amount of space is required, and a great quantity of ore must be at hand, as Well as the necessity of having propitious weather. But by my process and furnace I am enabled equally Well to treat the soft or clny'ey ore, which all mill-men lcnow to be the richest, and most difficult to work by the present known processes; also, by my process, the quichsilver is saved when working tailings or other ores.
Having thus described my invention, what I claim, and desire to secure by Letters Patent, `is- 1. The roasting of ores in moulds or chambers, substantially as described.
2.4 The arrangement of moulds containing orcs to be roasted, so that they can be gradually brought nearer the re or removed from it, substantially as described.
3. Removing the moulds containing ores from the re while undergoing the process, so that thedecompo sition may be conducted without additional heat, substantially as described. y
4. The placing of a. freshly-filled mould containing unroasted ore upon the top of a mould that has 'been removed from the fire, for the purpose of utilizing the excess of heat, substantially as described.
' 5. The arrangement of furnace, cooler, and crane, as described, for the purpose described.
6, The conducting of the fluo through water, or its equivalent, for the purpose of condensing the volatile matter, when used in connection with ores roasted in moulds, substantially :es described.
In witness whereof I have hereunto set my hand and seal.
