First immerse the end of the stirring rod in the acid. Remove it and touch that end to a paper towel to make a wet spot. Put a drop of gold detection liquid on the wet spot on the paper towel. If any gold is still dissolved in the acid, the wet spot will turn a purple-black or a purple-brown.
NOTE: IT IS POSSIBLE TO LEACH TOO LONG. ALL LEACHES KNOWN WILL BEGIN TO PRECIPITATE GOLD BACK INTO THE ORE AT SOME POINT. This usually doesn’t happen for as many as 72 hours, but in some ores it can happen in a few hours. WATCH FOR IT! Still available pre-mixed: CLS 25. CLS 25 is a very reactive leach for concentrates.
Gold Reservesays the project will feature two different mining plants, one, a 15,000-ton per day cyanidation plant and the other a 140,000-ton per day flotation plant.Goldcyanidation is technique used to extractgoldfrom minimum-grade ore. It’s the most commonly usedleaching processforgoldtoday.

Gold Cyanide Leaching Process - Outotec. Outotec's cyanide leaching plants are available as gold adsorption directly from the process slurry in carbon-in-leach (CIL) and carbon-in-pulp (CIP) processes. In addition, dissolved gold can be recovered from the solution after solid-liquid separation by Merrill-Crowe and carbon-in-column operations.
Heap leaching is always the first choice to process low grade ore easy to leaching. Based on the leaching test, the gold ore will be crushed to the determined particle size and then sent to the dump area. If the content of clay and solid is high, to improve the leaching efficiency, the …
