I frequently see Au grade of alluvial soil sample as both g/m3 and g/ton. I thought best practice is using g/m3 for alluvial. My questions: 1) why use g/ton? 2) how convert, say, .30g/m3 to g/ton? What is math? Thanks.

Alluvial Gold Mining - CDE Global

The first stage in alluvial gold mining is to take the dredged river bed material and separate the small sand faction (where the gold is found) from the larger mineral fraction. In a typical alluvial mining process physical separation methods such as screening and gravity separation are employed to separate the gold from the.

Placer deposit - Wikipedia

In geology, a placer deposit or placer is an accumulation of valuable minerals formed by gravity separation from a specific source rock during sedimentary processes. The name is from the Spanish word placer, meaning "alluvial sand". Placer mining is an important source of gold, and was the main technique used in the.
