Quartzassociated Gold Sorting : TOMRA

Whenever sulphide or quartz is associated with gold, the resultant gold ores are typically amenable to a certain degree of particle sorting. And in the case of the complex blend of quartz associated with gold, the preconcentration of the ore by means of sensorbased ore sorting during the early stages of the production process can be effected by harnessing the stering effect of a LASER beam.

Gold Ore Sorting : TOMRA

Sensorbased ore sorting transforms the bottom line in gold mining Exploring gold ores becomes more challenging every year. Mines increasingly deliver lower grades and complex mineralogy, forcing mills to process more material and thus compounding the expanding ratio between these tonnages and the ounces of ore produced.

Final Cleanup and Recovery of Your Gold

Sometimes placer gold just out of a streambed is very clean and shiny. If this is the case with your gold, after the final dry cleanup procedure is completed, your gold is ready to be weighed and sold or displayed or stored away in a safe place. Sometimes, gold will come out of a streambed with some impurities attached to it.
