US 7,012,209 B2 · Method of gold separation and gold separation device

Abstract

A method of collecting gold by flowing water over a gold collecting medium located in a sluice to induce a positive surface charge on the gold collecting medium. Feeding gold laden material into the sluice with the flowing water to induce a negative surface charge on gold particles of the gold laden material and create a slurry. Setting the flow rate of the slurry into the sluice such that the gold particles are attracted to the gold collecting medium. Finally, collecting the gold particles attracted to the gold collecting medium from the gold collecting medium. A gold separation device having a sluice having an input end and an output end; a water input directed into the input end of the sluice; and a gold collecting medium in the sluice. The gold collecting medium being of a material which incurs a positive surface charge when immersed in water.

Dependent claims

A method of collecting minus 20 mesh gold using a sluice including a gold collecting medium, comprising:

using water having a PH range between 4 and 8;
flowing the water over the gold collecting medium in a to induce a positive surface charge on the gold collecting medium due to the interaction between the water and the gold collecting medium;
feeding minus 20 mesh gold laden material into the sluice with the flowing water to induce a negative surface charge on minus 20 mesh gold particles of the colloidal gold laden material and create a slurry of minus 20 mesh gold laden material and water, whereby the water induces a negative surface charge on the minus 20 mesh gold particles;
setting the flow rate of the slurry into the sluice such that the minus 20 mesh gold particles are attracted to the gold collecting medium;
and
collecting the minus 20 mesh gold particles from the gold collecting medium that were attracted to gold collecting medium.
