Speed up your gold processing work and increase gold recovery with the Mountain Goat Portable Trommel. This machine is aptly named because it can eat almost anything and is light enough to carry up a mountain!

The Mountain Goat Gold Trommel is a reverse helix system built on the same principle as the huge mining trommels used by large mining companies all over the world, but this is light and portable. It is not to be confused with gravel pit trommels, though, which are designed to classify gravels.

The Mountain Goat is very efficient because the spiral riffles inside of the tube turn and bring the heavy materials up to the high end of the tube while allowing the lighter materials to flow out of the back of the tube as tailings. This system makes the trommel self-cleaning, which eliminates the need to break down for clean-up as is necessary in sluice box type equipment.

The spiral riffles in the trommel tube are .25 inch deep and spaced .75 inches apart. We suggest your placer material be screened to .5 inch or less even though rocks as large as .75 inch will pass through the tube. There is a nugget trap at the low end of the tube which should be checked regularly for nuggets larger than .25 inch.

The front legs of the trommel are adjustable to increase the pitch but we found that the factory setting is the best for getting fine or flour gold. The factory setting has the front legs about 1 inch longer than the back legs.

Any large tray such as a mortar mixing tub (found at most home improvement stores) can be used with 5 gallons of water which is recirculated by the 750 gallon per hour pump. The Mountain Goat can also be used directly in a stream and is a very sturdy machine designed to take a lot of wear and tear!
