01Common problems in zircon-titanium ore development

At present, our country's titanium zircon resources are highly dependent on foreign countries, and the price of imported zircon-titanium ore is high, which is greatly affected by sea freight prices and market prices. The ore dressing processes used by domestic zircon-titanium processing enterprises are mostly extensive, and the ore dressing processes of ore dressing and finishing plants are mostly unable to produce continuously, resulting in low comprehensive ore recovery rate and low product added value. At the same time, there is also a problem that a large amount of tailings after ore dressing have nowhere to be discharged, which has brought pressure to the ecological environment.

02Xinhai Mining's titanium-zirconium ore technology innovation

In recent years, Xinhai Mining has accumulated rich technical experience in the fine processing of coastal zircon-titanium ore and low-grade ilmenite, and has become an excellent zircon-titanium ore comprehensive processing project service provider at home and abroad. It has many unique features in production scale, product solutions, continuous production, automation, green and intelligent aspects, and has successively undertaken a number of titanium-zirconium and ilmenite projects in Guangxi, Hainan, Guangdong, Jiangsu, Xinjiang and Mozambique.

At present, Xinhai Mining has accumulated rich project experience in the processing and recycling of titanium-zirconium ore resources, and has achieved a combination of process innovation and equipment innovation, becoming an excellent domestic and foreign titanium-zirconium ore comprehensive processing project service provider. It has many unique features in production scale, product solutions, continuous production, automation, green and intelligent aspects.

1. 100% comprehensive recycling

100% comprehensive recycling, accurate recycling of useful minerals, no tailings discharge! Based on the traditional project that can only recycle ilmenite and zircon, the Shandong zircon-titanium ore project has optimized the process flow, using the differences in magnetism, specific gravity, particle size, and conductivity between minerals to accurately recycle 15 kinds of useful minerals, and realize the refined comprehensive recycling of all valuable minerals.

2. Automation and intelligence

Xinhai Mining has designed an automation system for the Shandong zircon-titanium ore project, which greatly reduces the labor intensity and operating errors of workers. At the same time, it has planned and designed centralized control rooms at the workshop level and the plant level, respectively, to monitor, analyze and operate the entire production process in real time, and improve the production automation and intelligence level of the ore dressing plant.

3. Intensive environmental protection design

The zircon-titanium ore dressing plant designed and constructed by Xinhai Mining adopts an intensive design, and the modern new steel structure plant is fast to construct, occupies less space, saves investment, and has a beautiful appearance. Water treatment, material transportation, dust and noise all adopt high-standard environmental protection design, green and low-carbon.

04Innovative technology for low-grade ilmenite

1. New crushing and grinding technology

Xinhai Mining replaced the conventional crusher with a high-pressure roller mill with large single processing capacity and high equipment operation rate, and grinded the ore to 1-0mm with high-pressure rollers, which truly achieved more crushing and less grinding in the ore dressing plant.

2. Ultra-fine powder ore dry separation technology
Xinhai Mining adopts ultra-fine powder ore dry separation technology, and the -1mm dry separation tailing rate reaches 50%, which not only reduces the amount of ore entering the mill and reduces the power consumption of the mill; it also reduces the pressure of the tailings pond stacking and reduces the area occupied by the tailings pond, making the mine green and environmentally friendly.

3. Titanium "strong magnetic + flotation" process
This process can enrich low-grade titanium to a floatable level before flotation, and then select it through a high-concentration flotation titanium process. The conventional flotation concentration is 30-40%, the high-concentration flotation concentration is 45%, and the ultra-high concentration flotation concentration used in this project is 50-60%, with good titanium selection effect and reliable technology.

4. Vertical mill regrinds titanium coarse concentrate

Vertical mill is a vertically installed fine grinding equipment with a stirring device. This equipment can grind finely and efficiently to prevent over-grinding; it is easy to install and occupies a small area; it has low vibration and low noise during operation, which can improve the working environment.

At present, the reserves and output of zircon-titanium resources in my country are relatively small, and the external dependence is high. The development and utilization of domestic zircon-titanium resources face certain challenges. As the proposer and practitioner of "Full Industrial Chain Service of Mining (EPCM+O)", Xinhai Mining will provide customers with intelligent, efficient and high-quality zircon-titanium project construction solutions through technological innovation, industrial upgrading and other measures, and help the zircon-titanium industry achieve high-quality development!
