The Invention includes obtaining, without the use of Mercury and cyanide, Gold Concentrate Law exceptionally high, on the Order of 10 to 70% of Gold, with over 90% Recoveries obtained in one or two stages of froth Flotation of Gold from Gold Bearing Gravel Fine laws ta N Low As 0,2 grams / tons; this procedure then allows direct and simple casting with borax Concentrate obtained for Gold Bullion semirefinado replacing the Gold Mining refogado that small scale obtained by Amalgamation for three Millennia.The process of froth Flotation processes combined with simple Gravity desliming in Cyclones, small diameter, Fine screening, Gravity concentration, sedimentation and Filtration to process different types of Gold Bearing Gravel or rock Minerals,Facilitate the Recirculation of Process Water and Reagents and guarantee effluent process with a dose of Flotation Reagent 200 times less than the Toxic dose for Trout fingerlings.The process uses a Flotation Collector comprising a commercial triple distilled extraction of high Toxic dose and guarantees fitness of Process even with inexperienced operators.The application of the combined process of Fine screening, Flotation desliming, and non cyanide leaching Gold from Gravel to deal directly with our and other tropical forest sites and obtain "Green Gold
