Fluorite is an important non-metallic mineral resource, widely used in metallurgy, building materials, chemical industry and other fields.
Fluorite is an easy-floating mineral. In the process of use, fluorite ore needs to undergo flotation treatment.
Five Key Parameters Affecting Fluorite Flotation
In the mineral processing, flotation is an important method mainly used for fluorite mineral processing. Effective minerals and non-minerals are separated through flotation to obtain high-quality products.
The key points that can affect fluorite flotation include: flotation process, flotation reagents, flotation equipment, etc.
In this article, we will start from these aspects and discuss these key points that affect fluorite flotation.
Fluorite flotation process
The fluorite flotation process mainly includes several stages such as rough selection, selection, and sweeping. According to the properties and requirements of fluorspar ore, different flotation processes can be adopted.
Fluorite ore is usually divided into two types: mixed ore and concentrate. In the flotation process, it is first necessary to adopt a roughing stage to float the mixed ore and the concentrate separately.
For mixed ore, gravity separation, magnetic separation and other methods are usually used for pretreatment to remove impurities, and then rough separation by flotation machine to separate different minerals such as fluorite and sulfide.
For concentrates, usually only need to go through simple roughing to meet the requirements.
After the roughing operation, the obtained fluorspar concentrate also needs to be subjected to a mineral processing operation to improve the grade and recovery rate of fluorspar.
Usually, advanced flotation technology (such as Czech, Netherlands, etc.) is used for selection operation, and selection conditions and drug use need to be mastered. The type and amount of flotation agents need to be adjusted precisely according to the properties of fluorite ore and process requirements.
After the mineral processing operation, it is usually necessary to further improve the fluorite grade and recovery rate through a sweeping operation, and at the same time remove residual impurities.
The sweeping process usually adopts methods such as multi-stage flotation and gravity separation, and the ore is sorted multiple times to obtain high-grade fluorspar products.
Fluorite flotation agent
Fluorite flotation agent is a key point and plays a vital role in the flotation process. The type, dosage and ratio of flotation reagents need to be adjusted precisely according to the properties of fluorite ore and the requirements of flotation process.
Collectors are chemical agents that bind to the surface of fluorite during flotation of fluorite. According to the properties of fluorite and the requirements of the flotation process, the collectors that can be selected mainly include sodium butyldithiooxalate, sodium oxalate, iron oxide, etc.
Blowing agents are chemicals used to create foam. Through the formation of foam, minerals with different densities and properties can be separated to realize the separation of fluorite and non-minerals.
Commonly used foaming agents include rosin oil, sulfated pine oil, and the like.
In the flotation process, the regulator is mainly used to control the characteristics of the mineral surface and affect the adsorption and action of the flotation agent. Commonly used modifiers include petroleum sulfonic acid, glycolic acid, etc.
Fluorite flotation equipment
Fluorite flotation equipment is a key point, including flotation machines, adsorption tanks, filters, etc. The selection and combination of equipment needs to be reasonably configured according to the properties of fluorite ore and the requirements of flotation process.
The flotation machine is a very important equipment in the fluorite flotation process. Commonly used flotation machines include mechanical flotation machines, gas flotation machines and centrifugal flotation machines. The choice of flotation machine can be reasonably selected according to the mining site and process requirements.
The adsorption tank is the reaction vessel after the fluorite and reagents are mixed in the flotation process. The size and type of the adsorption tank can be selected according to the mining site and process requirements. The material of the adsorption tank can be selected from high-strength alloy steel, steel plate or glass fiber reinforced plastic.
The filter is a key equipment in the fluorite flotation process. It can separate fluorite and water to get dry product. Commonly used filters include filter presses and centrifuges.
Process requirements for fluorite flotation
The technical requirements of fluorite flotation need to be paid enough attention and attention. The properties of fluorite ore and the use of fluorite flotation agents will affect the flotation effect and product quality.
Therefore, all aspects of flotation must be strictly controlled and the following requirements must be followed:
- Strictly control the dosage and proportion of medicines. The dosage and ratio of reagents are one of the key factors of flotation effect. The type and proportion of flotation reagents must be adjusted reasonably according to the nature of fluorite ore and the required grade.
- Strictly control the working conditions of the flotation machine. The operating conditions of the flotation machine have a great influence on the flotation effect and product quality. Factors such as the operating temperature, oxygen content and mechanical conditions of the flotation machine must be strictly controlled to ensure the stability and high efficiency of the flotation process.
- Strictly control the working conditions of the adsorption tank. The working conditions of the adsorption tank also have a great influence on the flotation effect and product quality. Factors such as the operating temperature, gas content and flow rate of the adsorption tank must be strictly controlled to ensure the complete reaction and separation of the flotation agent and fluorite ore.
- Fine tuning and operations management. In the fluorite flotation process, it is necessary to ensure the stability and high efficiency of the production line through fine debugging and operation management. The operating procedures, quality control and safety management requirements must be strictly implemented.
Fluorite flotation is a complex process integrating science, technology and management. It is necessary to have rich mining experience and professional technical ability, apply advanced flotation technology and equipment, and formulate scientific and rigorous mineral processing and management requirements in order to achieve efficient mining and high-quality production of fluorspar.
