[0002] The globalized market competition of the process industry is becoming increasingly fierce, mainly manifested in cost competition, product quality competition, and sales service competition. Among them, cost competition is the most basic and most critical. In the fierce market competition, cost reduction has become an important aspect of metallurgical enterprises. An important means and approach of competitiveness. The cost index is a comprehensive index to measure the production and operation activities of the enterprise. In most industrial enterprises, cost control is basically completed by manual quotations and other methods. Without real-time collection of complete cost data, it is impossible to d

specific Embodiment approach

[0019] The production index factors affecting the beneficiation process of a concentrator mainly include lump ore rate, waste rock rate, weak magnetic tailings grade, strong magnetic tailings grade, raw ore grade, etc. These factors directly affect the cost of mineral processing and refining. This implementation For example, based on the statistical data of these factors, a three-layer neural network BP model is constructed as the basic model for analyzing the impact of 5 factors such as the lump ore rate on the cost of comprehensive refinement. .
