solid minerals processing for gold ore

Here Is The Correct Way To Effectively Recognize Gold Ore

Gold mixes with different minerals which will affect the look of the ore If you are looking for larger chunks of gold stick to lode deposits where plate tectonic activity has brought gold to the surface Lode deposits usually form gold in larger veins so it should be easier to see Smaller flecks of gold are more common in placer deposit gold ore which tends to look like that area s
