Free-Milling Gold Gold ore is considered free-milling when over 90 of the gold can be recovered by a conventional gravity-cyanidation process with low reagent consumptions at a grind size of 80 passing 75 m. Some examples of free-milling gold ores include quartz-veined deposits and oxidized ores. Sulfide-Associated Gold
Grinding fineness; Generally speaking the determination of ore fineness is related to the characteristics of ore embedding. Different ore embedding forms gold particle size and form have certain influence on the determination of grinding fineness. Take a gold mine as an example.

The Cobra Crusher works by attaching to most standard Angle Grinders Steel Grinders. Recommended minimum power is 7 amps at 110v for when you're in the shop. Otherwise a strong 18v or higher professional grade battery powered machine works great for totally mobile prospecting and crushing.
The study of gold sites in the Migori Gold Belt Kenya revealed that the concentrations of heavy metals mainly Hg Pb and As are above acceptable levels. Tailings at the panning sites recorded values of 6.5–510 mg kg−1 Pb 0.06–76.0 mg kg−1 As and 0.46–1920 mg kg−1 Hg. Stream sediments had values of 3.0–11075 mg kg−1 Pb 0.014–1.87 mg kg−1 As and 0.28–348 mg kg−1 Hg.
