The motor-driven impeller rotates slowly after the V-belt, reducer, and gear reduce speed. The sand enters the washing tank from the feed tank and rolls under the drive of the impeller, grinding away the impurities covering the surface of the sand and gravel, and at the same time destroying the water vapor layer covered by the sand particles to facilitate dehydration.
This requires the adoption of high-efficiency, energy-saving, large-capacity, and high-recovery gravity beneficiation processes and beneficiation equipment. Gold Ore Gravity Beneficiation Process： 1. Original gold ore is crushed into under 15mm by jaw crusher machinery. 2. After crushing, material is transported into ball mill.

Ores are the primary source of obtaining minerals by mineral beneficiation. The process involves several steps depending upon the ore and its composition and properties. Ores are the aggregates of rocks or minerals from which the desired minerals are extracted. They can either contain minerals or metals that are economically important to humans.
In addition to gold, Oregon and Washington have sizable occurrences of other heavy minerals, such as chromite and ilmenite. Only a few successful attempts on recovering heavy minerals other than gold as byproducts from sand and gravel operations have been reported in the literature. Iron oxides were recovered from sand and gravel in England.
Both hand selection and gravity beneficiation can obtain coarse-grained metallurgical grade fluorite lump ore. However, the manual selection method has low efficiency and high labor costs, so it is only used for the pre-selection of large fluorite ores, and small pieces and granular fluorspar ores still need to be sorted by re-selection.
