In the mining sector, technological innovation is a key driving force for corporate development. Xinhai adheres to the concept of innovation, has carried out in-depth research and optimization on the flotation process of low-grade sulfide lead-zinc ores, aiming to improve the efficiency and quality of metal extraction, and ensure the rational use of resources.
After much effort, the technical team at Xinhai successfully developed a set of efficient solutions for the optimization of the flotation process. These solutions include the precise adjustment of grinding conditions and chemical regimes, which have significantly improved the individual liberation degree and metal recovery rate of the ores. In actual production, our optimization measures have not only increased the metal recovery rate but also effectively reduced production costs, enhancing the market competitiveness of the company.
Our optimization work primarily focuses on the following aspects:
By precisely controlling the grind size, we ensure the full dissociation of the ore, which enhances the efficiency of the beneficiation process. We employ advanced grinding equipment and technology to realize the precise management of the grinding process.
Through a series of laboratory and field tests, it was determined that the best grind size is where particles less than 200 mesh account for 78%-82% of the total, as this results in the greatest individual liberation and metal recovery rates. Additionally, adjustments to the ball mill configuration are made to maintain the overflow particle size within the target range, which prevents the loss of coarse particles and controls the metal loss caused by excessive fineness of the mine water.
Taking into consideration the different properties of the ores, we adjust the types and quantities of floatation agents used to achieve better floatation results. This measure effectively increases the grade and recovery rate of concentrate.
By comparing the effects of different medicines, it is found that the MIBC frother can significantly enhance the grade of lead concentrate and reduce the content of lead in the tailings, optimizing the separating effect of lead and zinc. Additionally, adjustments are made to the dosage of inhibitors for the rough selection of sulfide lead to reduce the circulation of minerals in the selected zone and increase the recovery rate of lead concentrate.
By redesigning and adjusting the flotation process, we have reduced the amount of ore circulation in the process and improved the stability of flotation operations.
In terms of process structure, the flotation machine configuration in the lead sulfide sweep II area has been innovatively adjusted. By installing a time cycle relay to control the scraping rhythm, the repetition of zinc metal in the cycle has been effectively reduced, and the overall stability and efficiency of the process have been improved.
The optimization of beneficiation process for low-grade sulfide lead-zinc ore is a systematic engineering project involving multiple aspects such as grinding fineness, chemical system, and process structure. By comprehensively utilizing scientific experimental data and continuously optimizing operational parameters, not only can the economic benefits of mineral processing operations be improved, but also the technological progress and sustainable development of the entire industry can be promoted. In the future, Xinhai will continue to devote itself to the research and innovation of mineral processing technology, continuously improve its technical level, and provide customers with higher quality products and services.
