What Are The Factors Affecting The Recovery Rate Of Beneficiation?

The mineral processing 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 dressing, mainly including the nature of raw ore, the beneficiation process, and beneficiation management. In this paper, we will analyze their impact on the recovery rate of ore dressing in detail from these aspects.

1. Ore properties

The influence of raw ore properties on the recovery rate refers to the influence of the grade, distribution relationship, occurrence state, physical properties, and chemical properties of the useful components in the raw ore on the percentage of useful components extracted from the raw ore. Generally speaking, the higher the grade of the raw ore, the higher the recovery rate because the higher the grade of the ore, the higher the content of useful minerals that are easy to select. The simpler the embedded relationship of useful components, the higher the recovery rate. The greater the difference in physical properties of various substances in raw ore, the higher the recovery rate, because various substances are easier to distinguish and separate during the mineral processing process. The greater the difference in chemical properties of various substances in raw ore, the higher the recovery rate, because various substances are more easily changed and separated during the mineral processing process.

2. Mineral processing technology

Different processes are suitable for different raw ore types, and choosing an appropriate process can improve the recovery rate. The optimization and improvement of the process can also increase the recovery rate. The impact of the optimization and improvement of the beneficiation process on the recovery rate mainly includes the following aspects:

A. Improve the degree of refinement of raw ore

The degree of refinement of raw ore refers to the particle size range suitable for mineral processing after raw ore undergoes physical treatments such as crushing and screening. Generally, the higher the degree of refinement of the raw ore, the easier the separation between useful components and impurities, and the higher the recovery rate.

B. Improve the equipment performance

Mineral separation equipment includes gravity separation equipment, flotation equipment, magnetic separation equipment, electric separation equipment, etc. The performance and efficiency of mineral processing equipment directly affect the mineral processing recovery rate. Optimizing and improving mineral processing equipment can improve its processing capacity, separation effect, stability, and reliability, thereby increasing the recovery rate.

C. Improve the rationality of the process

Optimizing and improving the beneficiation process can improve its adaptability, simplicity, continuity, and controllability, thereby increasing the recovery rate. New combined processes, modular processes, and intelligent processes can be adopted.

3. Mineral processing management

The impact of mineral processing management on recovery rate refers to the process of effectively monitoring, adjusting, and controlling the mineral processing process to ensure the stability and improvement of the mineral processing effect, thereby improving the mineral processing recovery rate. The impact of mineral processing management on recovery rate mainly includes equipment management and quality management.
