Case reasoning-based iron ore floatation reagent dosage optimization setting method and system

Abstract

The invention provides a case reasoning-based iron ore floatation reagent dosage optimization setting method and a case reasoning-based iron ore floatation reagent dosage optimization setting system. The method comprises the following steps: extracting historical data from the production process of iron ore floatation; establishing an iron ore floatation case library, wherein a floatation boundary condition and a process index target value serve as case description, and a floatation reagent dose serves as case solution; performing case retrieval in the case library to obtain a group of similarity values; arranging the similarity values from large to small and selecting the case description corresponding to the previous n similarity values to serve as reference case description of the current working condition; reusing the case to obtain a new case solution; when error is more than a set threshold value, correcting the case and generating a new case; finding the case description with the maximal similarity value with the case description of the new case through case retrieval to finish case library updating. By the method and the system, a reagent dosage setting value suitable for various working conditions is given out by virtue of measurable production data related to the iron ore floatation reagent dosage, so that the safety, the reliability and the economic performance of the iron ore floatation production can be improved.

Description

technical field [0001] The invention belongs to the technical field of iron ore flotation, and in particular relates to a case-based reasoning method and system for optimally setting the dosage of iron ore flotation reagents. Background technique [0002] In the iron ore flotation production process, a reasonable reagent system can effectively improve the concentrate grade and reduce the tailings grade. At present, most of the pharmacy systems are adjusted by manual experience, but inexperienced operators or misoperations by operators are likely to formulate wrong pharmacy systems, and in most cases the pharmacy systems remain unchanged for a certain period of time, the above The situation will inevitably lead to insufficient sorting of useful components in the pulp or excessive dosage of chemicals, resulting in low efficiency of iron ore flotation and waste of resources. A small number of iron ore concentrators use automatic dosing machines for chemical control, but automa...

At present, most of the pharmacy systems are adjusted by manual experience, but inexperienced operators or misoperations by operators are likely to formulate wrong pharmacy systems, and in most cases the pharmacy systems remain unchanged for a certain period of time, the above The situation will inevitably lead to insufficient separation of useful components in the ore slurry or excessive dosage, resulting in low efficiency of iron ore flotation and waste of resources

A small number of iron ore concentrators use automatic dosing machines for chemical control, but automatic dosing machines are expensive and require high maintenance costs, which increase the cost of beneficiation
