The output of titanium concentrate in Panzhihua Iron and Steel Co., Ltd.

From January to October, the titanium concentrate produced by Panzhihua Iron and Steel Group of Anshan Iron and Steel Group exceeded the total output in 2020, reaching the highest level in the same period in history, and the output scale steadily ranked first in the country.

In 2021, under the guidance of strengthening and optimizing the mineral resources industry system, Panzhihua Iron and Steel Mining Co., Ltd., in the spirit of "jumping up and touching high", broke the historical record of titanium concentrate output and laid a solid foundation for achieving the annual target. The company has set up a scientific and technological research team of titanium separation system, focusing on the superior forces of production, technology and equipment, and carrying out a series of key research activities, such as the technological process of titanium separation system, parameter optimization, upgrading of equipment and facilities, to ensure the goal of reducing cost, improving quality and stable production. In order to ensure the titanium concentrate production, the company actively adjusts the stope position, optimizes the ore matching organization, ensures the raw ore grade of the titanium concentrate, strengthens the fine management, improves the operation efficiency, supervises and controls the operation of each production line, quickly carries on the production anomaly rectification and production coordination, ensures the efficient and orderly operation of production, formulates the corresponding shift output tracking plan in the key production line, and tracks the output completion on a shift-by-shift basis.

As the main production line of titanium concentrate production, titanium separation branch strengthens process optimization and focuses on scientific and technological projects such as "improving the recovery and industrialization of titanium separation" and "experimental study on the washability of ilmenite". Explore the optimal process parameters of high intensity magnetic flotation to improve the recovery rate of titanium separation; After the implementation of the project, the titanium recovery rate has increased by 3.63% compared with the same period last year; the maintenance mode of the flotation machine has been optimized, and the assembly has been pre-assembled in advance, and the maintenance time of the flotation machine has been optimized from 3 days to 1 day, and the production capacity of the equipment has been significantly improved.

Centering on the production bottleneck, the New Baima Company has deeply carried out the efficient operation of the Baima titanium separation system, conducted a comprehensive examination of the process, found out the unreasonable metal loss points and key points in the process, and formulated solving measures. through the first section of tailings coarse compartment and secondary inclined plate between the complex vibration screen to promote the use of regional anti-blocking screen to reduce the metal loss in coarse-grained slag separation operation; The method of "ultrasonic cleaning + on-line cleaning" is used to effectively clean the high-intensity magnetic medium, increase the yield of the first-stage high-intensity magnetic operation, strengthen the process management and improve the yield of titanium concentrate. Since the beginning of this year, the titanium recovery rate of New White Horse has increased by 0.69% compared with the same period last year.

With the goal of "process optimization, cost reduction and consumption reduction", Xingmao Company has continuously carried out the reduction of high intensity magnetism and flotation tailings grade, the optimization of flotation reagent system, etc., adding 2 high intensity magnetic machines and updating 2 laminated screens, etc. continue to improve the level of technology. The scientific research of "development and demonstration of ultra-fine ilmenite recovery technology" and "construction of spare production line of inflatable flotation machine" has now entered the field experimental stage, which provides technical support for the next demonstration line construction. As of October, the titanium recovery rate of Xingmao was 3.72 percentage points higher than that of the same period last year.

The company is also actively around the growth target, pay close attention to the external production of titanium concentrate, in order to release the potential and expand the scale to enhance the stamina. Since the beginning of this year, the company has carried out full recovery in external production, changed the way of waste rock utilization in the dump, and returned the particles to the warehouse to recover titanium concentrate. From January to October, the total amount of waste rock resources in the dump was 6.9536 million tons, and the titanium concentrate was increased by 115900 tons.
