AMALGAMATlNG-FURNACE SPECIFICATION forming part of Letters Patent No. 273,275, dated March 6, 1883.
Application filed April 28, 1882.
To all whom it may concern:
promote thoroughness in the operation.
The invention consists in an amalgamatingfurnace constructed with separate fire-chamhers, and having in its upper part a horizontal tubular amalgamator connected by pipes with three tanks, through which and theamalgamator the amalgam is forced by a pump, making the circulation of the amalgam continuous. A represents the furnace, which is provided with a series of four fire-grates, B, more or less, separated by division-walls G, rising at little above the said grates, so as to form separate fire-chambers D and allow any desired number of separate fires to be maintained. The last fire-grate of the series is placed within the lower part of the stack E, as shown in the drawing.
In the upper part of the furnace A is placed the amalgamator F, in or nearly in a horizontal position. The amalgamator F is made in tubular form, and through it passes longitudinally a shaft, G, which revolves in stuffingboXes in the ends of the said amalgamator. The forward end of the shaft G projects through the end wall of the furnace A, and has a pulley, H, attached to it to receive a driving-belt. To the shaft G, within the amalgamator F, are attached arms I, to agitate and mix the ore and amalgam as they pass through the said amalgamator and insure the contact of every particle of ore with the amalgam.
The ore is introduced into the amalgamator F through the hopper J, the discharge-spout of which enters the forward part of the stack E and connects with the end of the amalgamator F in the forward part of the interior of the stack. The amalgam enters the inner end (No model.)
of the amalgamator F through the pipe K from the tank L, which is secured in the interior of the stack E at a higher level than the amalgamator F. At the outer end of the amalgamator F the ore and amalgam flow into the tank M, and the refuse ore flows over the upper edge of the said tank M into the casing N and passes down through thepipe 0 into the condensing-pipe P. The amalgam from the tank M flows through the pipe Q into the tank It, into which the amalgam is first put, and in which it is formed by the union of melted lead with mercury. From the tank R the amalgam passes through the-pipe S to the pump T,
by which it is forced through the pipe U into the tank L, to again pass through the amalgamator F, so that there will be a continuous circulation of the amalgam and a continuous discharge of refuse ore. I
The piston-rod V of the pump T is connected with a crank or crank-wheel, W, attached to the inner end of the shaft X, which revolves in bearings Y, attached to the stack E or to some other suitable support. 7
To the outer end of the crank-shaft X is attached a pulley, Z, to receive a driving-belt.
The amalgam is formed by melting lead in the presence of mercury, the two being preferably in about equal proportions. In this compound the quicksilver makes the melted lead more liquid, keeps it liquid should the heat fall below the melting temperature of lead, and prevents the lead'from oxidizing, so that it can be used in amalgamating gold and silver ores in a hot condition without loss of lead by oxidation.
The vapors of quicksilver that may be generated in the tanks R and L pass through the pipes on and b to the condensing-pipes c and d.
