Titanium tantalum ore is an important metal mineral widely used in aviation, aerospace, shipbuilding, chemical industry, electronics, metallurgy and other fields. The mining and beneficiation of titanium tantalum ore is a complex process that requires a series of methods and technologies to improve the grade and recovery rate of titanium tantalum ore. This article will introduce the beneficiation methods of titanium tantalum ore, including physical beneficiation, chemical beneficiation, flotation, and magnetic beneficiation.
1、 Physical beneficiation
physical beneficiation is a method of separating titanium tantalum ore using its physical properties, mainly including heavy medium separation, heavy mineral separation, and grinding classification. Among them, heavy medium separation is a commonly used physical beneficiation method that can separate titanium tantalum ore and waste rock through methods such as gravity separation, centrifugal separation, and airflow separation. Heavy mineral separation is a method that uses the density difference between titanium tantalite and other minerals to separate. It can be separated by shaking table, inclined shaking table, spiral separator and other equipment. Grinding classification is a method of separating titanium tantalum ore and waste rock according to their particle size, which can be separated through equipment such as screening, cyclone separation, and airflow separation.
II. Chemical beneficiation
chemical beneficiation is a method of separation using chemical reactions, mainly including oxidation roasting, leaching, and extraction. Among them, oxidation roasting is the oxidation reaction of titanium tantalum ore at high temperature, which releases and separates valuable elements in titanium tantalum ore. Leaching is a chemical reaction that involves soaking titanium tantalum ore in an acidic or alkaline solution to dissolve and separate valuable elements in the ore. Extraction is a method of separating and extracting valuable elements from a solution in titanium tantalum ore, which can be separated through extractants and extraction equipment.
3、 Flotation
Flotation is a method of separating titanium tantalum ore and waste rock by using the relative density difference in water, mainly including direct flotation, reverse flotation and composite flotation. Among them, direct flotation is a method of separating titanium tantalum ore and waste rock by directly floating them in water. Reverse flotation is the reverse flotation of titanium tantalum ore and waste rock under the action of reagents, resulting in the flotation and separation of titanium tantalum ore. Composite flotation is a method of multiple flotation and separation of titanium tantalum ore and waste rock in a multi-stage flotation machine, which can improve the grade and recovery rate of titanium tantalum ore.
4、 Magnetic separation
magnetic separation is a method of separating titanium tantalum ore and waste rock based on their magnetic differences, mainly including dry magnetic separation and wet magnetic separation. Among them, dry magnetic separation is a method of magnetic separation between titanium tantalum ore and waste rock under dry conditions, which can be separated by permanent magnet magnetic separators and high-strength magnetic separators. Wet magnetic separation is a method of wet magnetic separation of titanium tantalum ore and waste rock in water, which can be separated by a wet magnetic separator.
In summary, the beneficiation methods of titanium tantalum ore include physical beneficiation, chemical beneficiation, flotation, and magnetic beneficiation. Different beneficiation methods are suitable for different titanium tantalum ores and need to be selected and applied according to actual situations. In the beneficiation process, it is necessary to pay attention to controlling the beneficiation process parameters, improving the grade and recovery rate of titanium tantalum ore, while reducing environmental pollution and resource waste.
