Calcium titanium sand is an important mineral resource widely used in fields such as construction, metallurgy, and chemical engineering. During the mining process of calcium titanium sand, gravity beneficiation method is a commonly used technique, which can effectively improve the grade and recovery rate of calcium titanium sand. This article will introduce the operating steps and precautions of the gravity beneficiation method for calcium titanium sand, hoping to be helpful to practitioners in related industries.
1、 The principle of gravity beneficiation method for calcium titanium sand
The gravity beneficiation method of calcium titanium sand is a separation technology based on physical properties, which utilizes the different motion characteristics of mineral particles in the gravity field to achieve mineral separation. Generally speaking, titanium ore in calcium titanium sand is heavier than calcium ore, so its movement speed in the gravity field is slower, while calcium ore is relatively lighter and moves faster. Through this difference, titanium ore and calcium ore in calcium titanium sand can be separated, thereby improving the grade and recovery rate of calcium titanium sand.
2、 Operating steps of gravity beneficiation method for calcium titanium sand
1. Ore crushing: Firstly, it is necessary to crush the calcium titanium sand to ensure that its particle size meets the beneficiation requirements. Generally speaking, the particle size of calcium titanium sand should be controlled below 5mm.
2. Ore grading: Screen the crushed calcium titanium sand to separate ore particles of different sizes. Generally speaking, in the beneficiation process, it is necessary to use multi-layer screens for classification to ensure the accuracy and grade of ore particles.
3. Ore sorting: The graded calcium titanium sand is fed into the sorting machine for sorting. The sorting machine generally uses gravity sorting machine or centrifugal sorting machine to sort according to different sorting principles. The sorting effect of the sorting machine has a decisive impact on the grade and recovery rate of calcium titanium sand, so it is necessary to choose appropriate sorting machine models and parameters based on the actual situation.
4. Ore flotation: If there are many impurities in calcium titanium sand, flotation technology can be used for purification. During the flotation process, it is necessary to add certain reagents to cause chemical reactions between impurity minerals in calcium titanium sand and reagents, in order to achieve mineral separation and purification.
5. Ore drying: Dry the calcium titanium sand after beneficiation to ensure its moisture content meets the beneficiation requirements. During the drying process, temperature and humidity need to be controlled to avoid sintering and deformation of ore particles.
3、 Precautions for gravity beneficiation method of calcium titanium sand
During the beneficiation process, it is necessary to strictly control the accuracy and grade of ore particles to ensure the beneficiation effect.
2. Different types and parameters of sorting machines have a significant impact on the beneficiation effect, and they need to be selected according to the actual situation.
3. Flotation technology can improve the grade and recovery rate of ores, but it is necessary to control the amount of reagents added and reaction time to avoid affecting the quality of the ore.
During the beneficiation process, strict control of temperature and humidity is required to avoid sintering and deformation of ore particles.
In summary, the gravity beneficiation method for calcium titanium sand is a commonly used technique that can effectively improve the grade and recovery rate of calcium titanium sand. In practical applications, it is necessary to make reasonable selections and adjustments based on the characteristics of the ore and the beneficiation requirements to achieve the best beneficiation effect.
