The raw ore of the Shandong 1 million TPA zirconium-titanium ore beneficiation project is mainly imported from Africa, Madagascar, Southeast Asia, the United States, Ukraine, Australia, Brazil and other regions, and the raw ore mineral composition is complex. The process flow adopted by domestically imported zirconium-titanium ore concentrators is relatively simple. Only titanium and zirconium are recovered, resulting in serious losses of metal minerals and limited concentrate quality. This is a huge waste of raw ore imported at a high price. The intermediate products produced by the mineral processing plant are piled nearby on the ground. The state of the factory can be described as "dirty, messy, and poor". Customers hope that Xinhai Mining can help them achieve two purposes. One is to comprehensively recover all kinds of recyclable minerals to achieve no tailings emissions; the other is to refine the processing of each recyclable product to improve the quality of each product as much as possible. added value.

Xinhai Mining attaches great importance to this zirconium-titanium ore project. In the research and design process alone, it dispatched more than 30 professional and technical personnel to conduct repeated beneficiation tests and innovative process designs. After many on-site environmental inspections and studies of the project and multiple rounds of plan modifications,taking into account the needs of cost saving, environmental protection, safety, automation and other needs, the innovative process flow of Shandong 1 million TPA zirconium titanium ore project was finally determined:Raw ore scrubbing and desliming-titanium ore wet magnetic separation-magnetic tail classification-granulation grade gravity separation —Electric separation—sewage treatment process plan. Utilizing the differences in magnetism, specific gravity, particle size, and conductivity between minerals, up to 15 types of useful minerals can be accurately recovered. While achieving refined and comprehensive recovery of all valuable minerals, a modern zirconium and titanium concentrator with unique highlights has also been built.
Xinhai Mining Research Institute first conducted a professional beneficiation test on zircon titanium ore and issued the "Ore Selectability Test Report" for zircon titanium ore. It was concluded that the mineral embedded particle size from coarse to fine is: zircon, titanium Iron ore, rutile, monazite. Xinhai Mining Mining Design Institute referred to the test procedures recommended by the institute and combined with the project field environment, carried out the following process research and design innovations to achieve the comprehensive recovery of useful minerals and maximize the recovery rate.

1.Add a scrubbing and desliming process before wet magnetic separation:Zircon titanium ore contains 0.3% mud, which affects both wet magnetic separation and subsequent gravity separation. At the same time, mud will be distributed into all slurries, affecting the sewage treatment effect. In the innovative process of Xinhai Mining, a scrubbing and desliming process is added after slurry mixing to scrub away the mud and other impurities on the surface of the ore particles to provide relatively clean raw materials for subsequent wet magnetic separation and gravity separation operations. Titanium ore and The quality of valuable products such as zircon sand and rutile has also been further improved. At the same time, the amount of mud processed after scrubbing and desliming is greatly reduced, reducing the burden of subsequent sewage treatment work.

2.Add classification and narrow-grained re-selection before re-selection:For gravity separation operations using spiral chute and shaker, the narrower the range of other particle sizes, the better the gravity separation effect. In this design, grading operations are added before re-selection to enhance the re-selection effect.。

3.Repeated selection of intermediate products:Xinhai Mining's innovative design process fully considers the re-selection of intermediate products, repeatedly selecting the intermediate products produced in the zircon and rutile electro-selection stages, and maximizing the product recovery rate and efficiency through process design and equipment layout. Concentrate grade.
Xinhai Mining designed a mineral processing automation system for the Shandong 1 million TPA zirconium-titanium ore project. On the one hand, Xinhai Mining designed and implemented an automatic batching system, an automatic material distribution system and an automatic loading system for the project, which greatly reduced the number of workers. Labor intensity and operating errors have been eliminated, and the production efficiency and resource utilization of the dressing plant have been effectively improved.

On the other hand, taking into account the particularity and complexity of the zirconium-titanium ore process, Xinhai Mining has planned and designed centralized control rooms at the workshop level and factory level to conduct real-time data monitoring, analysis and operation of the entire production process to improve Improve the production automation and intelligence level of the mineral processing plant to create an intelligent green processing plant.
The zirconium-titanium ore dressing plant planned and constructed by Xinhai Mining Equipment adopts intensive design. All components of the plant except the foundation are made of factory It is produced in a centralized manner and assembled on site after being shipped to the site. The modern new steel structure factory building is fast to construct, takes up less space, saves investment and has beautiful appearance.

Inside the factory, Intensive design solutions are also adopted in the installation of magnetic separation and re-selection equipment. In the magnetic separation stage, the self-flow of the slurry is realized through the double-layer height difference design; in the gravity separation stage, the conventional practice of "building a shaking table on the ground and digging a pit underground" is changed, and the shaking table is arranged in multiple layers, >Save space.

1. Underground water treatment:Xinhai Mining designed a wastewater centralized treatment system for the Shandong zirconium-titanium ore dressing plant >, all process water in the processing plant is recycled to the water supply pool and returned to the production process for reuse to achieve zero discharge. The water supply tank of the dressing plant is designed as an underground pool, which can reduce evaporation and reduce the amount of new water added to the dressing plant. The total water consumption in the first phase of the project is 2055m³/h, the total return water volume is 2050m³/h, and the return water utilization rate is as high as 99.75%.

2. Materials do not fall to the ground:Xinhai Mining innovatively proposed a design plan of "Materials do not fall to the ground", which changed the previous mineral processing plant that was "dirty, messy, "Poor" environmental status. All raw ore and intermediate products are placed in the storage silo, with forklifts and forklifts removed as much as possible. Intermediate products are transported to the next process through belt conveyors. Except for the final finished product, which requires a forklift to enter the finished product warehouse, there are no forklifts elsewhere. operation, the entire dressing plant realizes continuous automated production.
