The gold grade in the original ore, calculated from the dough balance, is 2.07 g/t. The gold in the ore is mainly distributed in large grades, so more than 60% of the metal is in the + 1 mm grade. Due to the fact that the bulk of gold in the ore is concentrated in large grades, there is a high probability of finding unopened metal in it.

SAG mills are often used in conjunction with a ball mill or pebble mill to achieve the desired grind size. SAG mills are primarily used in the mining industry, particularly in the processing of gold, copper, and platinum group metals. On the other hand, AG mills, or Autogenous Grinding mills, use only the ore itself as grinding media.
