Selection Technology of Zirconium Titanium Sand Ore from Seashore

Seashore zirconium titanium placer ore is an important mineral resource, mainly distributed in Hainan, Guangdong, Fujian and other places in China. The mining and beneficiation technology of seaside zirconium titanium sand ore is crucial for China's economic and industrial development. This article will introduce the relevant knowledge of the technology for selecting seaside zirconium titanium sand ore, including beneficiation process, equipment, and operating steps.

1. Mineral processing technology

The beneficiation process of seaside zirconium titanium placer ore is mainly divided into several stages, such as gravity separation, magnetic separation, and electrostatic separation.

1. Reselection

gravity separation is the process of separating the raw ore into heavy and light ores. The heavy ores of coastal zircon titanium placer are mainly Rutile, ferrotitanium, Ilmenite, etc., and the light ores are mainly quartz, feldspar, etc. Gravity beneficiation generally uses hydraulic or heavy medium beneficiation to achieve the separation of heavy and light ores through the difference in settling speed of minerals with different densities in water flow or heavy medium.

2. Magnetic separation

Magnetic separation is a process that utilizes the different response characteristics of minerals to magnetic fields for sorting. Ferrotitanium and Ilmenite in coastal zircon titanium placer are both magnetic and can be separated from non-magnetic light ores such as quartz and feldspar by magnetic separation. Magnetic separation is generally carried out using a weak magnetic field separator.

3. Electrostatic selection

Electrostatic sorting is the process of sorting by utilizing the different response characteristics of minerals to electrostatic fields. The Rutile, Ilmenite, etc. in the coastal zircon titanium placer have strong static electricity, which can be separated from the non static quartz, feldspar and other light ores by electrostatic separation. Electrostatic sorting is generally carried out using high-voltage electrostatic sorting machines.

2、 Equipment

The equipment for selecting seaside zirconium titanium sand ore mainly includes heavy medium separator, magnetic separator, high-voltage electrostatic separator, etc.

1. Heavy medium sorting machine

The heavy medium separator is an important mineral processing equipment mainly used in the gravity separation process. Its working principle is to achieve the separation of heavy and light minerals by varying the settling speed of minerals with different densities in water flow or heavy media through the action of hydraulic power or heavy media. At present, the common heavy media sorting machines in the market include cyclones, sievers, etc.

2. Magnetic separator

Magnetic separator is an important mineral processing equipment mainly used in the magnetic separation process. Its working principle is to utilize the different response characteristics of minerals to magnetic fields for sorting. At present, the common magnetic separators in the market include wet magnetic separators, dry magnetic separators, etc.

3. High voltage electrostatic sorting machine

High voltage electrostatic separator is an important mineral processing equipment, mainly used in the electrostatic separation process. Its working principle is to utilize the different response characteristics of minerals to electrostatic fields for sorting. At present, the common high-voltage electrostatic sorting machines in the market include plate type high-voltage electrostatic sorting machines, drum type high-voltage electrostatic sorting machines, etc.

3、 Operating Steps

The operation steps of selecting seaside zirconium titanium sand ore mainly include the crushing, gravity separation, magnetic separation, electrostatic separation, and other links of the raw ore.

1. Crushing of raw ore

The raw ore is generally large and needs to be crushed to facilitate subsequent beneficiation operations. Crushing is generally carried out using equipment such as jaw crushers and cone crushers.

2. Reselection

The crushed raw ore is subjected to gravity separation to separate heavy and light ores. Gravity beneficiation generally adopts hydraulic beneficiation or heavy medium beneficiation.

3. Magnetic separation

The heavy ore after gravity separation is subject to magnetic separation to separate ferrotitanium ore and Ilmenite. Magnetic separation is generally carried out using a weak magnetic field separator.

4. Electrostatic selection

The magnetically separated ferrotitanium ore and Ilmenite are subject to electrostatic separation to separate Rutile, etc. Electrostatic sorting is generally carried out using high-voltage electrostatic sorting machines.

4、 Summary

The technology of selecting seaside zirconium titanium sand ore is an important task, which requires the use of appropriate beneficiation processes and equipment, and the operation is carried out according to standardized operating steps in order to achieve efficient, stable, and safe beneficiation process. This article introduces the relevant knowledge of beneficiation process, equipment, and operating steps, hoping to be helpful for the learning and practice of zirconium titanium sand ore beneficiation technology in coastal areas.
