We will carry out alluvial gold mining, the material content consists of rock with a diameter of 0.5 mm - 100 mm, we will use an excavator for excavation and filter it using a tromel tool to separate coarse rock with a diameter of 10 mm-100 mm and a diameter below 10 mm along with other minerals including gold filtered through the sluice box tool where the gold and mineral followers are retained on the base of the carpet attached to the sluice box ..... the result of this process is to separate gold from other minerals such as zircon, iron, silver etc ... for help us in this process whether the magnetic separator product from your factory can function for this process .... thank you
