ore preparation process of grinding

Ore processing Waihi Gold

Ore is stockpiled (1) at the processing plant, and the process begins by feeding the ore into a hopper with a loader. The ore is conveyed, and lime is added (2) to raise the pH of the ore. Following crushing through a jaw crusher (3), the ore is fed into the semi autogenous grinding (SAG) mill (4) along with water and steel balls.

On neural network structure selection to solve problem of

The possibility of creation the neural network model for predicting the iron content in the output product of grinding process of the ore-dressing industry is considered in this paper. The use of this range of tools is determined by the multifactoriness and non-linearity of the process, and by the need of the model to adapt to changing parameters. The study consisted in modeling of various
