The Flotation of Alluvial Gold. Gravity methods of recovering alluvial gold are not very efficient at particle sizes below about 0.1mm. Whereas such gold may not have been economic to recover in the past, the same may not be true today._x000D_ Centrifugal concentrators, like the Knudsen and Knelson bowls, are showing promise after an inauspicious start, at least in New Zealand.

Besides, gold flotation process can be used to process pulse gold ore and alluvial gold. But since alluvial gold can be economically recovered by gravity extraction process, gold flotation process is rarely used. Gold Flotation Steps. Gold flotation process mainly includes the following steps: Preparation for the ore before gold flotation process.

This washing plant is suitable for recovering alluvial gold ore containing sticky clay. If the raw ore doesn't contain much sticky clay, we recommend a trommel screen instead of a trommel scrubber. The capacity for this washing plant can be customized as per request such as 10tph, 50tph,100tph, 150tph, etc.

"A number of technologies are in practice for selectively removing coarse gold from conventional grinding circuits. These circuits are often designed so that the grinding mill output is size classified, with large (or high density) particles being removed before the tails are returned to the mill. Because of the high relative SG of gold, and the fact that some forms of gold such as …
