Abstract: © 2016 Association of Chemists and Chemical Engineers of Serbia. All rights reserved. This paper presents an application of computational intelligence in modeling and optimization of parameters of two related production processes-ore flotation and production of balls for ore flotation. It is proposed that desired chemical composition of flotation balls (Mn = 0.69%; Cr = 2.247%; C = 3.79%; Si = 0.5%), which ensures minimum wear rate (0.47 g/kg) during copper milling is determined by combining artificial neural network (ANN) and genetic algorithm (GA). Based on the results provided by neuro-genetic combination, a second neural network was derived as an intelligent soft sensor in the process of white cast iron production. The proposed ANN 12-16-12-4 model demonstrated favorable prediction capacity, and can be recommended as a ‘intelligent soft sensor’ in the alloying process intended for obtaining favorable chemical composition of white cast iron for production of flotation balls. In the development of intelligent soft sensor data from the two real production processes were used.
