The ore beneficiation recovery rate refers to the percentage of useful components extracted from the raw ore, and is an important indicator to measure the mineral processing effect. There are many factors that affect the recovery rate of ore beneficiation, mainly including the properties of raw ore, beneficiation process, and beneficiation management. The following will analyze their impact on the recovery rate of ore beneficiation in detail from these aspects.

01Raw ore properties

The influence of raw ore properties on recovery rate refers to the influence of grade, embedding relationship, occurrence state, physical properties, chemical properties and other factors of useful components in raw ore on the percentage of useful components extracted from raw ore. The influence of raw ore properties on the recovery rate mainly has the following aspects:

01Grade of useful components

Generally speaking, the higher the grade of raw ore, the higher the recovery rate. Because the higher the grade of ore, the higher the content of useful minerals.

02 Embedding relationship of useful components

The embedding relationship of useful components refers to the way and degree of combination between useful components and other substances in raw ore. Generally speaking, the simpler the intercalation relationship of useful ingredients, the higher the recovery rate.

03 Physical properties of raw ore

The physical properties of raw ore refer to the characteristics of various substances in raw ore in terms of shape, structure, density, hardness, color, luster, etc. Generally speaking, the greater the difference in physical properties of various substances in raw ore, the higher the recovery rate, because various substances are easier to be distinguished and separated during the beneficiation process.

04Chemical properties of raw ore

The chemical properties of raw ore refer to the characteristics of various substances in raw ore in terms of composition, reactivity, solubility, redox and other aspects. Generally speaking, the greater the difference in chemical properties of various substances in raw ore, the higher the recovery rate, because various substances are easier to be changed and separated during the beneficiation process.

02Mineral beneficiation process

Mineral beneficiation process refers to the method and step of extracting useful components from raw ore, including crushing, screening, gravity beneficiation, flotation, magnetic beneficiation, electroseparation and so on. Different processes are suitable for different raw ore types, and choosing the right process can improve the recovery rate. At the same time, the optimization and improvement of the process can also improve the recovery rate, and the impact of the optimization and improvement of the mineral processing process on the recovery rate mainly has the following aspects:

01 Improve the refinement of raw ore

The degree of refinement of the raw ore refers to the particle size range suitable for beneficiation after the raw ore has undergone physical treatment such as crushing and screening. Generally speaking, the higher the degree of refinement of raw ore, the easier the separation between useful components and impurities, and the higher the recovery rate. However, excessive refinement will also increase energy consumption and loss, and reduce recovery rate. Therefore, it is necessary to determine a reasonable degree of refinement according to different raw ore types and process requirements.

02Improve the performance and efficiency of mineral processing equipment

Mineral processing equipment refers to mechanical equipment used to separate useful components and impurities in raw ore, including gravity separation equipment, flotation equipment, magnetic separation equipment, and electric separation equipment. The performance and efficiency of mineral processing equipment directly affect the recovery rate of mineral processing. Optimizing and improving mineral processing equipment can improve its processing capacity, separation effect, stability and reliability, thereby increasing the recovery rate.

03 Optimize the selection and use of beneficiation agents

Mineral dressing agents refer to chemical substances used to change the physical or chemical properties of useful components or impurities in raw ore to achieve their separation, including flotation agents, leaching agents, precipitation agents, etc. The selection and use of beneficiation agents have an important impact on the recovery rate. Optimizing and improving beneficiation agents can improve their selectivity, activity, stability and environmental protection, thereby increasing the recovery rate.

04 Improve the rationality and flexibility of the beneficiation process

The beneficiation process refers to the specific steps and sequence of extracting useful components from raw ore, including pretreatment, roughing, beneficiation, sweeping, dehydration, etc. The rationality and flexibility of the beneficiation process also have an impact on the recovery rate. Optimizing and improving the beneficiation process can improve its adaptability, simplicity, continuity and controllability, thereby increasing the recovery rate. For example, adopt new combined processes, modular processes, intelligent processes, etc.

03Mineral beneficiation management

The impact of beneficiation management on the recovery rate refers to the process of effectively monitoring, adjusting and controlling the beneficiation process to ensure the stability and improvement of the beneficiation effect, thereby improving the process of the beneficiation recovery rate. The impact of beneficiation management on recovery rate mainly includes the following aspects:

01Equipment management

Equipment management refers to the effective maintenance, repair and update of mineral processing equipment to ensure the normal operation and high-efficiency performance of the equipment, thereby improving the recovery rate. For example, formulate reasonable equipment maintenance plans and overhaul plans to detect and eliminate faults in time. Perform performance tests and evaluations on equipment regularly, and update and replace outdated or damaged equipment in a timely manner. Introduce advanced equipment technology and management methods to improve equipment automation and level of intelligence.

02Quality management

Quality management refers to the effective monitoring, analysis and control of mineral processing raw materials, products and processes to ensure the stability and improvement of mineral processing quality, thereby increasing the recovery rate. For example, establish sound quality standards and testing methods, conduct regular testing and analysis of raw materials, products and processes. Adjust process parameters and conditions in a timely manner based on quality data, and optimize separation effects. Establish an effective quality feedback mechanism to promptly solve quality problems and Improved quality levels, etc.

The above are the three aspects that affect the recovery rate of ore beneficiation. In addition to the recovery rate, there are many factors to measure the beneficiation effect, which need to be judged according to the specific situation and need to be considered and balanced comprehensively. Through the analysis and optimization of these factors, the recovery rate of ore dressing can be improved, thereby improving the effect and benefit of ore dressing.
