Product Description:
The Micro-Sluice gold and black sand Heavy Duty Concentrator model needs No pre-classifying. Pre-screening is NOT required! Designed and patented by John McCann this work horse gold concentrator is based on the very popular Micro-Sluice 2 design. It uses a "double-deck / high banker" type design and will accept any size material and retain the gold from 4 mesh (1/4") down to very minute 200 mesh!

The Micro-Concentrator will outperform any gold wheel in terms of accuracy, speed, or value! No pre-classifying or pre-screening of material is required! Just run your material straight into the unit. Highly portable, with a size and weight of 12" x 25" (folded up) and only 14 pounds, the Micro-Concentrator will process up to 300 lbs per hour. The accuracy is typically 95-98% for visible gold and 60-90% for sub-visible (free milling gold), down to around 200 mesh.



The optional Micro-Moss Extender Sluice, or HFBE Quicksand Vibrator is recommended for those "difficult" jobs with heavy black and micron or "flour" gold.

With the unique water recycling system and ability to handle most any size material without pre-classifying, the Micro-Concentrator is the first truly portable, mini high banker! A 1250 GPH high efficiency pump, with two nozzles, circulates water from buckets or pools, using only 3 amps x 12 VDC. This will allow about 10 hours use on a car battery or, for true portability as a high banker, 3.5 hours of use on a light motorcycle battery (Battery not provided). Designed for heavy duty use, the Micro-Concentrator will provide years of reliable operation with either the 12VDC pump version or with included hose adapter.

Four aluminum legs provide a sturdy and accurate means of mounting to the HD 5 gallon Pump/base Bucket (provided). Built in angle indicator guarantees you always will have the correct angle of the sluice box and easily repeatable good results.

In operation, the upper "hopper sluice" can be fed any size material which dissolves in the water flow to form an ore slurry. This passes over the 1/4" grizzly. Oversized material is automatically rejected and the 1/4" minus material passes into the lower sluice. The slurry now passes over a micro-classifying plate, with a total of 2,318 x 16 mesh holes and into more quiet water. The sub-visible gold is collected in this manner. Larger particles pass into the sluice where rubber v-grooves, mesh and riffles capture 95-98% of the visible gold. Any quantity of black sand concentrate will be reduced to only three tablespoons of "super-concentrate" which will pan to clean gold in 5 minutes. The unique triple classification system produces a truly 1st class gold recovery machine!

The Micro-Concentrator is ideal for desert use as a wet recycler, on river banks or small pools - the anywhere gold machine! With all Micro-Sluice Gold Products, reliability is their hallmark. The Micro-Concentrator will outperform any gold wheel in terms of accuracy, speed, or value!

BONUS: although not designed as such, Rock Hounds in the southeastern U.S. describe the Micro-Concentrator as an "AWESOME" machine for separating & classifying gem stones.

The Micro-Concentrator has a full one year limited warranty.

Micro-Sluice Concentrator includes a bunch of stuff: 2 buckets, scoop, float pump kit, Micro-Moss Extender assembly, and a dual hose adapter.

Please note - Item is shown with optional upgrade: Heavy Duty HFBE Vibrator. Add the optional HFBE Vibrator for even greater fine gold separation.
