Zircon sand is an important non-metallic mineral with extensive applications in industrial production. The gravity beneficiation process of zircon sand is a commonly used method for beneficiation of zircon sand, which can effectively separate useful minerals from zircon sand, improve the grade and recovery rate of the ore. This article will introduce the gravity beneficiation process and operating steps of zircon sand.
1、 Gravity beneficiation process flow of zircon sand
The gravity beneficiation process of zircon sand usually includes the following steps:
1. Crushing: Crush the original zircon sand ore to meet the particle size requirements suitable for entering the beneficiation equipment.
2. Grinding: Grind the crushed zircon sand ore to achieve finer particle size requirements for subsequent gravity separation.
3. Gravity separation: The ground zircon sand ore is sorted through gravity separation equipment to separate useful minerals from it.
4. Grinding: The zircon sand ore after gravity separation is further ground to improve the ore grade and recovery rate.
5. Magnetic separation: The finely ground zircon sand ore is subjected to magnetic separation treatment through magnetic separation equipment to separate the magnetic minerals from it.
6. Flotation: The magnetically separated zircon sand ore is subjected to flotation treatment using flotation equipment to separate the non magnetic minerals from it.
2、 Operating Steps
1. Crushing: The original zircon sand ore is fed into a crusher for crushing treatment. The particle size of crushed ore is generally below 10mm.
2. Grinding: The crushed zircon sand ore is fed into a grinding machine for grinding treatment. The particle size of the ore after grinding is generally below 0.074mm.
3. Gravity sorting: The ground zircon sand ore is sent to the gravity sorting equipment for sorting and processing. Gravity sorting equipment includes flotation machines, spiral sorting machines, vibration tables, etc. The ore grade after gravity separation can generally reach over 60%.
4. Grinding: The zircon sand ore after gravity separation is fed into a grinding machine for further grinding treatment. The particle size of the ground ore is generally below 0.04mm.
5. Magnetic separation: The finely ground zircon sand ore is fed into magnetic separation equipment for magnetic separation treatment. Magnetic separation equipment includes wet magnetic separators, dry magnetic separators, etc. The ore grade after magnetic separation can generally reach over 65%.
6. Flotation: The zircon sand ore after magnetic separation is sent to the flotation equipment for flotation treatment. Flotation equipment includes air flotation separators, stirring drums, etc. The ore grade after flotation can generally reach over 70%.
III. Summary
The gravity beneficiation process of zircon sand is a commonly used method for beneficiation, which can effectively separate useful minerals from zircon sand, improve the grade and recovery rate of the ore. In practical operation, it is necessary to make reasonable selection and combination based on specific ore properties and characteristics of beneficiation equipment to achieve the best beneficiation effect.
