Barring Furnace
Our fuel fired barring furnace technology with which balances the weight of the upper pivoted furnace weight, resulting in reduced toque demand during furnace tilting. Reduced torque curve means reduced drive jitter and better pouring control. This means smaller torque worm gear drives and more accurate tilting control. Available with VSD worm gear drive or higher tech servo motor drive technology. Features also include horizontal crucible loading and pivoted lid opening. No more vertical loading of heavy handle-less crucibles under that annoyingly positioned furnace hood. Ideal for use with our FEMS high capture rate, low profile extraction systems. DESIGN

Unique patented linear spiral counterweight technology for balancing empty furnace body

Hinged furnace lid with horizontal loading design of crucible

Worm gear electric motor drive standard

Optional servo motor drive control for enhanced tiling control

Small Fire Assay Kit

US$4,000

This Beginners FIRE ASSAY KIT has as equipment required to help miners with their laboratory startup. Probably the most important factor of success in prospecting and gold recovery mill operation is the number of assay completed - you can do 6 assays at a time with this Kit. At one time, fire assaying was a deep dark secret. Now in this modern world, education can be had by those who want to learn. Many miners have learned to do their own fire assays and we offer complete fire assay kits with instructions! Simply mix your ore with our Premixed Flux (non-leaded flux available for international sales-obtain & add lead locally) in a Crucible. Place it in the Furnace. In an hour, pour the entire batch into the Pouring Mold. When it has cooled, break off the lead button that has formed. Place the lead button on a Cupel and back into the Furnace. Soon any precious metals present will remain in the form of a small bead. All materials and equipment are included in this kit so that you can do your own assays and determine the weight of the bead, without other equipment. The Advanced Fire Assay Kit offers additional equipment and supplies to the Beginners Fire Assay Kit, including the Automatic Temperature Control for the Furnace. The Analytical Balance is an easy-to-read digital unit. An excellent laboratory setup for any operation striving towards professional results. (You may substitute the #9 furnace with a larger one for the difference in the price.) Power: 110 or 220 VAC BASIC BEGINNER $4,000 EXPERT ADVANCE $11,000

Electric Melting Furnace
This is our industrial size electric melting furnace for non-ferrous metals such as Copper alloys, Aluminium, Zinc, Silver, Gold.

HEATING ELEMENTS: our standard is FeAlCr (2,300°F). These coil elements are winded up around a ceramic tube for support. It gives a better heat distribution because all the surface of the elements is in contact with air. We use low-density elements which offer a longer lifetime. For copper alloys, we use Silicon Carbide (SiC) elements for higher power and temperature (2,550°F).

QUALITY INSULATION: 7” of insulation; 4 ½" thick low-density refractory bricks (rated 2,600°F) and 2 ½” fibreboard (mineral fibre rated 1,900°F). At the bottom, underneath the crucible, we use castable and refractory bricks together.

TEMPERATURE CONTROLLER C/W HI-LIMIT OVERSHOOT PROTECTION: our standard controller is Watlow Ez-Zone PM6 (1/16 DIN).

HI-LIMIT OVERSHOOT PROTECTION: this device will shut the furnace when the preset temperature is exceeded. A reset button has to be pressed by the operator in order to get the furnace to heat up again.

QUIET OPERATION: the electric version is much quieter than the gas version. The gas version includes noisy equipment; air combustion blower, gas nozzle, etc.

TO EMPTY THE MELTING FURNACE: two different versions are available; the tilting version which tilts with the use of hydraulic cylinders. With the stationary Version, an operator needs to use a ladle to take the metal in fusion and pour it into moulds.

EASY TO INSTALL: these furnaces are "plug and play”. The customer needs to install the crucible, connect the electricity supply (or gas) and go through "Initial firing schedule” of the operation manual supplied with every unit.

HOW TO OPEN THE FURNACE: the furnace was designed with a lever very easy to operate. To move the cover, lift the lever and push it sideways (swing top cover with lateral displacement).

CRUCIBLE: our standard is SiC. Other materials are available.

Note: this is our standard design. We can adapt standard models to accommodate your customer’s requirements.

12″ Gold Ore Smelting Kit Furnace

US$2,000
This propane fired furnace can smelt ore concentrates, fire assay, melt pure metals, old scrap jewelry. Included in your home Gold Ore Smelting Kit KK12 :

will be a custom USA built precision machined

bi-metal brass tipped Propane Burner,

6' Hose with 30 psi regulator and needle valve,

Olympic Analog Pyrometer

Kiln liner maintenance kit.

A5 clay of a 15 lbs capacity (brass) (900 cc) or 17 kilos of gold if filled to the rim.

Alumina Silica Refractory interior rated for up to 2300° F.

The KK-12 is constructed of a stainless steel tension adjustable jacket, surrounding alumina silicate refractory insulation that comprises the interior of the kiln. The refractory insulation has an operating temperature rating of 2300° F. We offer the only sectional kiln that allows for easy removal of the crucible before pouring. The liner of the kiln is constructed in a layered and stacked configuration and is less susceptible to cracking from thermal expansion and contraction, as each layer can expand or contract separately. Another feature of the layered and modular design is that individual sections of the kiln liner can be replaced at a fraction of the cost of replacing the whole liner, in the event of a serious spill or boil over of the crucible. Of course, instruction Manual included.
Deluxe Gold Smelting Furnace
The Deluxe KK-12 Kit will include: An A5 clay graphite Salamander crucible and 10 pounds of our premium black gold flux - or - white flux for silver or copper. Shipping box will be 20" x 15" x 15" and weight will be around 38 pounds or 43 lbs deluxe.

Small Metal Melting Furnace: Beginner Kit

US$200

Portable propane fired Metal Melting Kiln designed to melt precious metals with speed and ease. Melt 1 to 6 oz of fine placer gold (1 to 3 oz silver). The Melting Furnace KKiln has a straight/vertical chamber and is a bit taller. The mini graphite crucibles are custom made for the kwik kiln. Other sizes will not fit properly. The GPK Kwik Kiln is designed to be heated with 2 pencil tip PROPANE torches simultaneously. Mag-Torch MT-200 pencil tip torches are highly recommended by our designer, for being more stable. They are an ‘all position’ torch and work well with the propane bottle on its side, are all brass and are made in the USA. Please note: We cannot warranty any GPK Kwik Kiln heated too high, improperly, or in a manner that goes against their design. This includes using other types of torches, or using Mapp gas, which gives off more heat. We recommend using propane only.
