Zirconium ore is a very important mineral resource in China, which is rich in mineral resources. As a type of zirconium ore resource, it is very important to master the gravity separation process of seaside sand zirconium ore. This article will introduce the gravity separation process of seaside sand zirconium ore and provide detailed operating steps.
1、 Overview of Seashore Sand Zirconium Mine
Seashore sand zirconium ore refers to the zirconium bearing sand ore distributed in the coastal sand zone. Its main minerals are zircon and siliceous minerals. Its ore properties are fine-grained, low-grade, and difficult to select. Therefore, the beneficiation process of seaside sand zirconium ore is relatively complex.
II. Gravity Separation Process Flow of Haibin Sand Zirconium Mine
The gravity separation process of Haibin Sand Zirconium Mine mainly includes: raw ore crushing, screening, gravity separation, intermediate separation, selection, tailings treatment, and other links. The following will provide a detailed introduction to each link.
1. Raw ore crushing
Raw ore crushing is to crush coastal zircon sand into Granularity suitable for further processing. Its main equipment is jaw crusher, cone crusher, impact crusher, etc. The Granularity of crushed ore is generally controlled below 5mm.
2. Screening
Screening is the process of screening the crushed ore according to its particle size for subsequent gravity separation. Its main equipment includes vibrating screens, rotary vibrating screens, etc. Generally, it is divided into two stages: coarse screening and fine screening, with a mesh size of 10mm for coarse screening and 1mm for fine screening.
3. Reselection
gravity separation is the process of gravity separation of screened ore to separate zircon and siliceous minerals. Its main equipment includes heavy medium sorting machines, spiral sorting machines, etc. During the process of re selection, it is necessary to control the density of the ore slurry, usually between 2.8 and 3.2g/cm ³。
4. Successful selection
Middle selection is the process of sorting the re selected zircon into intermediate products to separate higher grade zircons. Its main equipment is Gaussian magnetic separator, sorting machine, etc. During the selection process, it is necessary to control the flow rate and magnetic field strength of the ore slurry, generally selecting a magnetic field strength of 5000-10000 Gauss.
5. Selection
Selection is the fine sorting of selected zircons to improve their quality. Its main equipment includes heavy medium sorting machines, centrifugal sorting machines, etc. During the selection process, it is necessary to control the density and sorting speed of the slurry, usually between 3.2 and 3.5g/cm ³ And 200-300r/min.
6. Tailings treatment
Tailings treatment refers to the treatment of selected tailings to meet environmental requirements. Its main equipment includes filter presses, thickeners, etc. In the process of tailings treatment, it is necessary to control the density and concentration of the slurry, which is generally controlled between 35% and 40%.
3、 Summary
The gravity separation process of Haibin Sand Zirconium Mine is a complex task that requires mastery of various equipment and technologies. This article provides a detailed introduction to the gravity separation process of Haibin Sand Zirconium Mine and provides detailed operating steps, hoping to provide assistance to zirconium ore beneficiation workers.
