Micro-Sluice Gold Concentrators are among the finest gold recovery equipment available on the market. They offer hand-made products crafted from quality materials that perform to your highest expectations.
The Micro-Sluice Gold Products line has no equal in terms of accuracy, speed and cost efffectiveness.
Some of the most common questions about Micro-Sluice Black Sand Concentrators:
Q: How does the Micro-Sluice work?
A: The Micro-Sluice utilizes a feed hopper into which water is automatically added. The resulting slurry exits through drain holes in a consistent manner. The material then pass over a classifier plate with small holes to capture the finest materials. Then the slurry passes over a riffle system that utilizes a v-grooved rubber mat pioneered by Micro-Sluice Gold Products to capture even the finest gold. A built-in angle indicator guarantees the correct angle of the sluice and repeatable results.
Q: Why is this system better than wheels, bowls, look a likes, etc.?
A: In a word, EFFICIENCY! If you define efficiency as accuracy multiplied by speed divided by cost (AxS/C), the Micro-Sluice is a clear leader. We are 50% less than the cost of a wheel, 10X the speed of a bowl or "gutter" tubes and we are more accurate than either (up to 99%)!
Q: 99%! How can you make such a claim?
A: Fair Question. In 1990, John McCann struck a pay streak on the Trinity River. He and his partner recovered 1,374 grains of gold (nearly 3 ounces) in 10 working days. Each day they did a clean up from their 6" dredge. Each time about 50 pounds (2-1/2 gallons) of black sand concentrates were processed through a Micro-Concentrator (with a HFBE Vibrator). Once completed they ran the entire 500 pounds through again to evaluate for losses. All they recovered was 3.5 grains more! (Note that the gold was as fine as 80 mesh.) He documented the tests and has provided them to me. I have duplicated these results on much smaller quantities.
Q: Can I expect to have problems with a Micro-Sluice product?
A: While no one can absolutely guarantee 100% reliability, we do offer a full one year warranty against defects in materials or workmanship. In addition, we use only the best materials in the manufacturing process. Our sluices, for instance, are precision molded from heavy, 3/16" high impact plastic (other products use thin aluminum or thin plastic). Additionally, we have only one moving part!
Now after 20 years and over 3,700 units sold in 16 countries, Micro-Sluice is known worldwide. Quality products for recreational prospectors and serious miners alike.
The "Micro Sluice Jr." cleanup sluice offers unbeatable gold recovery at a budget price. Concentrates over 30 lbs per hour (2+ gallons) of any preclassified 1/8" mesh or smaller material and retains up to 95% of all visible gold!
Designed by John McCann, a mechanical engineer, the lightweight (3 lbs.) back-packable Micro-Sluice Jr. processes dry or wet concentrates at the rate of over 2 gallons per hour and will retain more than 95% of all visible gold. A high efficiency 400 GPH, marine pump, using only 1.0 amps x 12VDC, allows 30-40 hours of operation on a single car battery. Micro-Sluice Jr. is 100% field portable with 8-10 hours of run time on a motorcycle battery (battery is not included).
The Micro-Sluice Jr. is ideal for dry or desert use as a wet recycler. Up to 1/4 cu.yd. of material can be processed with only 5-10 gals of water via use of the exclusive "float-mounted-pump."
Now an industry standard, our pioneered v-groove rubber mat allows for an instant value check so you can see your gold right away! The Micro-Sluice Jr. patented technology uses a custom molded wide, flat bottom - unlike narrow "rain gutter machines" to assure maximum recovery of all of your gold (we are 50% wider)!
The Micro-sluice Jr. 6" wash-down tube is provided to flush out your gold pan or sample bottle and for final clean out. The float-mounted-pump guarantees no lost gold as tailings can be run through again to check for proper operation. The Micro-Sluice Jr. will reduce up to 1/4 cu. yd. of material into 1-2 tablespoons of "super concentrates" making the final pan clean-up less than 5 minutes. The Micro-Sluice Jr. is the most economical product in the Micro-Sluice concentrator line.
We are the king of the "black sand". Anyone can recover gold from light "blond" sand - we demo with heavy "black" sand and do it better than the competition. Compared with other products which are generally slower, and/or higher priced, the Micro-Sluice Jr. is a superior gold recovery machine in accuracy, speed & value!
Reliability is a hallmark of all of the products made by Micro-Sluice Gold Products. Over 3,600 Micro-Sluice units have been sold in 16 countries over the last fourteen years!
