Coastal Tantalite is an important mineral resource, which contains tantalum, iron and other metal elements with important industrial applications. In the development of mineral resources, beneficiation is a very important process, and gravity beneficiation is one of the important beneficiation processes. This paper will introduce the gravity beneficiation process of coastal Tantalite ore to help readers understand the operation steps and technical points of the process.
1、 Overview of gravity beneficiation process for seashore Tantalite
Gravity beneficiation is a beneficiation method that utilizes gravity to separate minerals based on physical properties. In the gravity beneficiation of coastal Tantalite, gravity separation, heavy medium separation, centrifugal separation and other methods are mainly used. Through the separation of minerals with different densities in ores, the purpose of improving the grade of Tantalite and reducing impurities is achieved.
2、 Gravity beneficiation process flow of seashore Tantalite
1. Ore crushing
First, seashore Tantalite is treated by coarse crushing, fine crushing and other processes to meet certain particle size requirements. Usually, equipment such as cone crushers and jaw crushers are used for ore crushing.
2. Heavy medium sorting
The crushed coastal Tantalite is added to the heavy medium by the heavy liquid method, that is, heavy substances are added to the water to separate minerals of different densities in the ore under gravity. The purpose of heavy medium separation is to separate impurities from ores and improve the grade of Tantalite.
3. Gravity sorting
After the heavy medium separation, the ore is placed in the gravity separation equipment for separation. Gravity sorting equipment usually uses equipment such as cyclones, spiral sorting machines, and gravity flotation machines. Under the action of gravity, minerals with different densities will be separated from the equipment to improve the grade of Tantalite.
4. Centrifugal separation
centrifugal separation is an efficient separation method that utilizes centrifugal force to separate minerals from ores. In the centrifugal separation of coastal Tantalite, the centrifugal separator is usually used to put the gravity separated ore into the centrifugal separator for separation, so as to improve the grade of Tantalite and reduce impurities.
5. Magnetic separation
magnetic separation is a commonly used mineral processing method, which uses magnetic differences to separate magnetic minerals from ores. In the magnetic separation of seaside Tantalite, a strong magnetic separator is usually used to put the centrifugally separated ore into the strong magnetic separator for separation, so as to improve the grade of Tantalite and reduce impurities.
3、 Advantages and disadvantages of gravity beneficiation process for seaside Tantalite
(1) The gravity beneficiation process is simple and easy to operate.
The gravity beneficiation process has a wide range of applications and can handle various types of ores.
(3) The gravity beneficiation process has less environmental pollution.
(1) The gravity beneficiation process has low beneficiation efficiency and cannot completely separate impurities from the ore.
(2) The beneficiation grade of gravity beneficiation process flow is affected by the mineral density distribution in the ore.
(3) The equipment investment and operating cost of gravity beneficiation process are relatively high.
The gravity beneficiation process flow of seaside Tantalite is an important beneficiation method, which separates ores through gravity separation, heavy medium separation, centrifugal separation and other methods to improve the grade of Tantalite and reduce impurities. Although the gravity beneficiation process has certain drawbacks, its advantages cannot be ignored. In actual production, suitable beneficiation processes should be selected based on specific circumstances to achieve the best beneficiation effect.
