Mineral Sampling - ScienceDirect
01.01.2016· A gold ore was crushed in a jaw crusher down to 3 mm and to 1 mm in a cone crusher and finally in a rod mill to minus 75 μm and sampled at each stage. The standard deviation at the first stage was ±10 ppm, ±1 ppm at the second stage and ±0.1 at the third stage. The confidence level in assaying was 3.0 ± 0.1%. Estimate the minimum mass of sample to be taken at each stage.

Load the solid gold ore into your crucible then load the furnace with charcoal. Light the charcoal and let it ash over. Set the crucible directly on the charcoal. Load more charcoal around the crucible. Turn the hair dryer on low to force air into the chamber below the charcoal. If the temperature fails to get high enough to melt your ore, turn the hair dryer up to high. Be very careful not to

Ball Mill Critical Speed
A Ball Mill Critical Speed (actually ball, rod, AG or SAG) is the speed at which the centrifugal forces equal gravitational forces at the mill shell's inside surface and no balls will fall from its position onto the shell. The imagery below helps explain what goes on inside a mill as speed varies. Use our online formula The mill speed is typically defined as the percent of the Theoretical

Effect of RPM Rod Mill Speeds
In a study of rod-mill discharge openings of different sizes, four pairs of tests were made at speeds of 40, 50, 60, and 70 percent of critical. In each pair the discharge openings were 8.0 and 4.5 inches, respectively. The tests were conducted so that the tons per horsepower-hour were nearly the same. This manner of conducting the tests gave about the same amount of sub-sieve size in each

A combination of rod mill and ball mills are then used if the ore must be ground below 325 mesh (45 μm). Instead of grinding the ore dry, slurry is used as feed for rod or ball mills, to avoid dusting. Oversize and undersize materials are separated using a screen; oversize material goes back for further grinding.

Rod mills, how they function - Mine Engineer.Com
Rod mills are very similar to ball mills, except they use long rods for grinding media. The rods grind the ore by tumbling within the the mill, similar to the grinding balls in a ball mill. To prevent the conditions leading to rod charge tangling, the length to diameter ratio is maintained at 1.4 to 1.6. Rod mills accept feed up to about 50 mm (2 in.) and produce a product in the size range of
