Data mining involves processing huge amounts of digital information to find hidden patterns and financial relationships. To executives, the findings are like gold, but on the weekends, I prefer seeing the real thing in the bottom of my pan.
Shaker Tables for Processing Hard Rock Ores
Most placer equipment is really made with gold in the 30 and larger mesh sizes in mind, though if carefully used can often get reasonable recovery down to the 50 mesh size.
Small-Scale Hard Rock Mining With Water Recycling
Once I have established the presence of gold in the sample, I collect five-gallon bucket quantities of the rock material for processing back at my shop.

A New Method for Handling Stubborn Gravity Middlings

High Sulfidation Epithermal Deposits
They tend to be big, coming in large to extremely large sizes. They can also be amazingly rich and produce huge amounts of very high-grade ore.
