Washing, is an enrichment method utilized to improve the value of a mineral by removing organic impurities attached to the rock. Different machinery and techniques are used depending on the strength of joins between the impurities and the recoverable mineral. Washing equipment can be used for a wide range of valuable minerals, however majority of Walker Mining machinery of this category is intended for washing gold.
Gold wash plant such as the sluice box and gold pan make use of gravity and the medium of water to wash the gangue minerals away, while the gold amalgamator and mercury retort make use of a chemical process involving mercury to obtain the final product.
What suggestion when alluvial gold & hard rock gold both exsist in your minesite , if your budget is limited
for alluvial gold and hard rock gold,the further processing methods(after the alluvial gold is dissociative from the sand, but the rock gold is covered by others mineral.So for the alluvial gold you need only washing and then shaking you will get pure gold; But for hard rock, you need to use some chemical to extract the gold(by cyanidation),it is much more complex and higher cost .Most of the customers will start the alluvlal gold mining first and with their experience grows, then they add the hard rock mining again. Below is the flowsheet for alluvial,Hard rock,Elluvial gold processing plant .
