What are the common problems in the process of preparing titanium from ilmenite?

Titanium iron ore is an important mineral resource widely used in the preparation process of titanium. However, in the process of preparing titanium from ilmenite, some problems are often encountered, which not only affect production efficiency but may also affect the quality of the final product.
The basic characteristics of ilmenite: ilmenite is a mineral containing titanium and iron, with high comprehensive utilization value. Titanium iron ore is not only an important source of titanium, but also associated with various useful elements such as vanadium, chromium, cobalt, and nickel. According to the vanadium content in ilmenite, it can be divided into low vanadium ilmenite and high vanadium ilmenite. Different types of ilmenite have different beneficiation processes.
The beneficiation process of ilmenite mainly includes crushing, grinding, magnetic separation, flotation and other steps. The beneficiation process of low vanadium ilmenite usually involves crushing the raw ore to around 3-5mm and then processing it with more crushing and less grinding. The grinding process is basically the same as the conventional single magnetite process, and vanadium is mainly associated with ilmenite. The beneficiation process of high vanadium ilmenite is similar to the recovery process of single magnetite. Some mines use pre grinding permanent magnet high gradient magnetic separation to discard waste, and weak magnetic separation tailings to recover ilmenite.
Common problem one: Complex mineral properties
The ore properties of ilmenite are complex, often containing various associated minerals such as vanadium, chromium, cobalt, nickel, etc. The presence of these associated minerals makes the beneficiation process more complex and increases the difficulty of beneficiation.
Common problem 2: Improper selection of mineral processing equipment
The selection of beneficiation equipment has a significant impact on the beneficiation efficiency. If the selection of beneficiation equipment is improper, it may lead to low beneficiation efficiency and even affect the quality of the final product.
Common problem three: Improper selection of flotation reagents
Flotation is an important step in the beneficiation process of ilmenite, and the selection of flotation reagents has a significant impact on the flotation effect. If the selection of flotation reagents is improper, it may lead to poor flotation efficiency and affect the grade of the concentrate.
Common problem four: Improper tailings treatment
Tailings treatment is an important part of the ilmenite beneficiation process. Improper tailings treatment may lead to environmental pollution and even affect the normal operation of the beneficiation plant.
Common problem five: Unreasonable beneficiation process flow
The rationality of the beneficiation process has a significant impact on the beneficiation effect. If the beneficiation process is unreasonable, it may lead to low beneficiation efficiency and even affect the quality of the final product.
Summary
In the process of preparing titanium from ilmenite, problems such as complex ore properties, improper selection of beneficiation equipment, improper selection of flotation reagents, improper tailings treatment, and unreasonable beneficiation process flow are often encountered. To address these issues, methods such as adopting a combined process flow, selecting appropriate beneficiation equipment and flotation reagents, treating tailings reasonably, and optimizing beneficiation process flow can be used to solve them. By continuously optimizing the beneficiation process and equipment, the beneficiation efficiency and concentrate quality of ilmenite can be improved, providing reliable guarantees for the preparation of titanium.
