Drum sand and gravel washers are suitable to wash ores with the size of below 80mm. Take manganese ore for example, if the silt content of manganese ore is 80%, this figure can become smaller than 15% after they are washed by sand and gravel washer so that the ores can meet technological requirements and hit the economic target.

Minerals are found in the Earth's crust throughout the world. Where there is a high concentration of a mineral, this is referred to as a mineral deposit. If it is socially, environmentally and economically viable, a mineral deposit can be mined and the extracted mineral can be processed for many different uses.
