This washing plant is very suitable for recovering alluvial gold ore that doesn't contain sticky clay. If the raw ore contains much sticky clay, we will recommend a trommel scrubber instead of a trommel screen. The capacity for this washing plant can be customized as per request such as 10tph,50tph,100tph, etc., Free Process Design Consultation.
Gold processing is about preparing the gold ore for using it in different products. The vital gold ores come with gold in the Indigenous form. It is available in both endogenetic as well as exogenetic forms. Gold in the endogenetic form comes from the underground. On the other hand, the exogenetic form is available at the earth's surface.
