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.

The grinding fineness can be appropriately improved to improve the recovery rate. The particle size of gold suitable for mercury mixing is generally 0.2-0.3mm, and the minimum particle size of mercury mixing plate in the grinding cycle is 0.015mm, but the finer gold particles are more likely to be lost with the pulp.

The crude ore from the mines contain a number of solid phases in the form of an aggregate. The valuable portion of the ore is known as mineral while the worthless portion is known as gangue. During ore dressing, the crude ore is reduced in size to a point where each mineral grain becomes essentially free so as to make separation between them.
