Advanced System for Control Milling and Flotation Processes Based on an Estimation of Ore Quality Grade

Abstract:

Ore processing plays a very important linking role between the mining and the metallurgical steps. The recent R&D achievements in this field resulted in the increase of the intellectual content of technological processes of mineral processing, as well as its automatic control. The main reason of mineral processing fluctuations is a mixing of ores from various sections of a deposit. Instability and non-optimized parameters of milling and flotation take 3% to 6% of losses of valuable component. Milling and flotation process are characterized by considerable fluctuations of all input, output and intermediate parameters. In these conditions, applying various mathematic models the process controlling by action on input parameters with further precise reaching the required values of output parameters of the process is not always possible. The application of the multilevel process models allows elaborating and using methods of the ore grade estimation and evaluation of the technological process situation by adaptive control.
