Since gold is a large specific gravity mineral with a specific gravity of 19.32 g/cm3, fine gold will deposit at the corner of the river (slow flow rate), forming the placer gold deposit where you looking for. The actual formation of geological structures varies widely. River gold is generally in the sand layer and not in the rocks.

Abstract In order to investigate the effect of particle size on the flotation performance in the separation of copper-gold-lead, froth products of various size fractions were collected as a function of flotation time. The optimum dosage of potassium dichromate (K2Cr2O7) and sodium diethyldithiocarbamate (DDTC) were determined by flotation conditional tests.

5. Separation of mud and sand-flotation. Some concentrators will use a "sand separation" process to achieve the extraction of copper from sulfide ore. After the ore is ground and classified, the mud and sand are flotated separately. Most of the gangue enters the fine mud part and becomes waste tailings in the flotation process.
