Zircon ore is an important mineral resource, among which zircon is an important mineral that can be used to manufacture high-end ceramics, refractory materials, electronic components, etc. The process of selecting zircon ore is very crucial. Below, we will introduce the process of selecting zircon ore.
1、 Properties of zircon ore
Zirconite is a Silicate mineral, whose main components are zirconia and silica. The hardness of zircon ore is relatively high, generally ranging from 7 to 8 grades, with a density of 4.6 to 4.7g/cm ³。 Zircon ore has a variety of colors, including white, gray, yellow, brown, red, etc.
2、 Technological process for selecting zircon ore
1. Crushing
Firstly, the zircon ore is crushed using a jaw crusher for primary crushing, followed by a cone crusher for secondary crushing. The particle size of crushed zircon ore is generally 10-30mm.
2. Grinding
The crushed zircon ore needs to be ground, usually using a ball mill for grinding. The particle size of zircon ore after grinding is generally 0.074-0.4mm.
3. Selection
After grinding, zircon ore needs to be sorted, usually using the gravity separation method for sorting. Gravity separation is a method of separating zircon from other minerals by using the density difference between zircon and other minerals. After sorting, zircon concentrate and tailings can be obtained.
4. Flotation
After sorting, the zircon concentrate needs to undergo flotation, usually using a forward and reverse flotation method for flotation. Positive flotation refers to the first flotation of impurities such as iron ore and titanium ore, followed by the flotation of zircon ore. Reverse flotation refers to the first flotation of zircon ore, followed by the flotation of impurities such as iron ore and titanium ore. After flotation, zircon ore flotation concentrate and tailings can be obtained.
5. Concentrate processing
After flotation, the zircon flotation concentrate needs to undergo concentrate treatment. Concentrate processing generally includes methods such as magnetic separation, electrical separation, and gravity separation. After processing the concentrate, high-purity zircon ore products can be obtained.
3、 Summary
The process of selecting zircon ore is a complex process that requires multiple steps to obtain high-purity zircon ore products. The process of selecting zircon ore includes steps such as crushing, grinding, sorting, flotation, and concentrate treatment. In actual production, adjustments and optimizations need to be made based on the properties and requirements of the ore to improve the efficiency and product quality of zircon ore selection.
