Principles of particle reduction. The most common method for obtaining a homogeneous sample is grinding of comminution. Grinding samples has many benefits for sample preparation since it increases homogeneity, increases surface area and decreases particle size which can improve extraction efficiency.

• Ball Mills or Ball-Medium Mills grind through impact of a grinding media such as balls, rods, etc. • Vibratory or Shaker Mills use high speed vibrations and grinding media to combine multiple grinding forces to reduce materials to fine powders. These mills can include grinding forces and media like balls, beads and grinding media.

(Horst 1985, p. 3A-5). Average grinding sizes for the ore can be brought down to 10-15 microns at the very most, if using long grinding periods on a product which has already passed a -200 mesh sieve. Some specific mills are reported to be available, which are capable of grinding the ore down to sizes of 5 microns or less.

A double deck screen is the correct choice for this application so particles that are too big for sorting are sent back to the cone crusher, and particles that are too fine are removed. The screen panel openings for the two decks need to be sized correctly to ensure the success of both jobs. Finally, the screen area size should also be sufficient.
