Here Is The Correct Way To Effectively Recognize Gold Ore · Gold ore does not usually have any shiny gold on the surface. Spotting it with the untrained eye does not always yield results; it's better to try a jeweler's loupe. Then it is possible to see flecks of gold sometimes. It is usually not possible to find gold ore with a metal detector.
Grinding control strategy on the conventional milling ...milling circuit consists of a rod mill followed by a ball mill in series. Crusher product (9 mm) is fed to the rod mill, and the water is fed in ratio to the ore feed mass. The rod mill discharge is pumped, without any further water addition, to the first ball mill. The ball mill discharges to a sump where water is

Rock CrushersWhen a rock has values in it, it's then called ore. In order to liberate the minerals, it needs to be crushed down. In days of yore, a stamp mill was the primary form of crushing rock, but in the modern world, there are jaw crushers, impact mills and gyrator crushers, as well as ball mills. They all have their own pros and cons and price tags.

MILLING CONTROL OPTIMISATIONore treated was very difficult to mill. In the first two days, the mill experienced numerous power dips (overloads), and on at least seven occasions the feed to the mill had to be completely stopped to grind the mill out. Also, the mill load varied in the range of 125 to 165 tons. These disturbances propagated throughout the milling circuit and ...
Geochemistry of hydrothermal gold deposits: A review ... · Although oreforming fluids derived from magma are common, hydrothermal systems without distinct affinities to magmatic activity can also result in the formation of large hydrothermal ore deposits (, Au, Ag, Pd, Zn, Sb, Hg, etc.). A significant portion of the world's natural gold endowment comes from hydrothermal ore deposits (Frimmel, 2008).

FLOWSHEET DEVELOPMENT FOR GOLD OREBODIESore. Relatively coarse gold particles that are liberated from the gangue mineral phase by crushing and grinding are readily recovered by gravity techniques, because of the large difference in specific gravity between gold (SG ) and most gangue minerals (SG 2 to 3). For gold ores that are amenable to gravity separation, recovery of the coarse,
