This paper investigates the comprehensive optimization of production processes based on Kaizen tools using the example of the 2nd Hydrometallurgical Plant of the Navoi Mining and Metallurgical Combine. The study analyzes ore processing operations carried out by ball mills in the crushing department, identifies production losses (muda), and proposes methods for their reduction. Mechanisms for improving production
efficiency are developed based on the 5S system, visual management, OEE indicators, and digital monitoring. Mathematical modeling is applied to
evaluate production efficiency, product quality, and economic performance. The results demonstrate that the implementation of Kaizen tools enables increased processing capacity, reduced defect rates, and improved resource utilization efficiency.
