While attempting to create an artificial reef to improve surfing conditions, Oregon scientist and microscopist David Plath discovered a unique way to separate micron sized gold from beach sands. From Asia to Africa, Australia and the Americas, Cleangold has been proven to be a powerful, efficient, gravity recovery method for the extraction of free micron gold, platinum and other minerals of commerce.
Particularly significant is Cleangold’s ability to recover fine gold from black sands (magnetite) without the losses typically associated with toxins or the investment in expensive, conventional systems requiring large amounts of clean water, power or maintenance.

Story is somewhat funny. We wanted first to buy mercury and make money on it, instead we are winning with Cleangold. I came to Tanzania 2012 to buy gold, however, the deal was fake, and then we had to figure out how to recover some lost money. We found out that there is huge market for mercury in Tanzania and that just nobody imports mercury legally. Then I have started researching about mercury, and I found out that those village miners would never be able to keep up with all of the regulations. If we would ever sell mercury we would cause environmental disaster. Until that point of time I did not know the environmental issues of mercury, and when we found out about it, I said stop, and that there is no way we would ever import mercury or make money on it. Instead we started researching various gold recovery methods, and UNDP reports on mercury alternatives. From those two sources of Grayson and UNDP, I could find about Cleangold. Then I started conversation with David which I value so much. It is interesting that every statement of David has so much strength and truth. He said to me not to waste time and money on various gadgets for gold recovery as Cleangold is enough. It has been shown in the field that Cleangold outperforms large Chinese made gold recovery plant. We got challenge in January 2022 in Uganda to process 50% concentrates with Cleangold, and we recovered 13 grams with Cleangold while other group recovered 10 grams with mercury. I hope to make a significant change as soon we will start presenting it and pushing it into governments here in East Africa. —Mr. Jean Louis, Mentor, www.startyourowngoldmine.com
“Gravimetric methods may be used to concentrate ore to get a smeltable product and is optimal for certain ores. However, often the finer gold particles are lost when using gravimetric methods due to turbulent flow, not-spherical gold particles, etc. Often the gold-grains are combined with other, lighter minerals, often with sulphur bonds which need to be broken e.g. by thermal treatment. The Cleangold sluices appears to separate fine gold particles better than any other gravimetric method.” -Dr. Lars Hylander, Professor, University Uppsala, Sweden
“Myself, along with other professionals of the mining area, have been undertaking the implementation of the technology developed by Cleangold in order to recover fine gold of past mining activities in gold areas in Bolivia. My country Bolivia is and has been an emminently mining country, although the sustainability issues (environmental and quality of life) have been sacrificed at the expense of the short term economic benefits. Within this scope, environmental awareness and economic development of communities located where the Cleangold technology has been implemented, has demonstrated a very positive result considering the old practices implemented in the region where mercury affected not only the quality of the water resources and fauna, but also the health and life of people.” A.V., Bolivia.
“We are currently designing a large filtration plant with multi-set ups to handle the high volume we will be processing, now that our Exploitation permit has been issued. As you can see from results, that using your system increased greatly the amounts of recoverable gold and other precious metals, as calculated in previous studies as well as our re-verification study (Dec08-April 09). Those studies are what our 24 month proforma is based on being calculated as 1/2 gram per cm3, and now expected to average 2+gramsAu cm3.” - D. A., Peru
