Submerge the unrefined gold in a mixture of nitric and hydrochloric acids. This method will dissolve the ore and separate the gold from the impurities which can later be washed away. The remaining substances will be just water and gold the latter having a purity level of more than 99.99 percent. Dry this residue until only gold powder remains.Get A Quote

Sep 11 2020018332In most cases a single dry technology alone does not meet the separation of all materials and these technologies need to be coupled for a complete separation
Cyclone separators or simply cyclones are separation devices dry scrubbers that use the principle of inertia to remove particulate matter from flue gases. Cyclone separators is one of many air pollution control devices known as precleaners since they generally remove larger pieces of particulate matter. This prevents finer filtration methods from having to deal with large more abrasive .
Our vibratory gold wash plant the SV9 aka Monster Red is rated up to 450 tons per hour. This design allows for nuggets and fine gold recovery. The SV9s horizontal design allows for much lower feed height and improved cleaning action of materials. It accepts up to 8-inch material and incorporates two to three decks for thinning and separation.
