how to wash gold from sand washing plant trommel. Trommel scrubber is a kind of equipment used to wash ores in industries such as ferrous metal nonferrous metal metallurgy and mining The washing process is Add clear water to such equipment and remove impurities such as mud and sand of the raw core dissolved in water After such washing process the ores can meet technological requirements
The sand is fed onto a screen where water is added to wash the sand into a sump, from where it is pumped to the plant. Most sand dumps have already been retreated using more efficient milling methods. Slimes dams are also the result of older treatment methods, although they are more recent than sand dumps, and contain lower grades of gold.
