Gravity separation method and steps for zirconium titanium sand ore

Zirconium titanium placer is an important mineral resource widely used in aviation, aerospace, military, electronics and other fields. However, the separation of zirconium titanium sand ore is not easy because its density is similar to other minerals, so gravity separation method is needed. This article will introduce the method and steps of gravity separation for zirconium titanium sand ore.

1. Gravity separation principle of zirconium titanium sand ore

Gravity separation is to use the density difference of mineral particles to make them have different movement tracks in the gravity field, so as to realize the separation of minerals. The density range of zirconium titanium sand ore is 4.2-4.6g/cm ³， It is similar to Magnetite, Hematite and other minerals in density, so gravity separation method is required for separation.

2、 Gravity separation method for zirconium titanium placer ore

1. Heavy medium method

The heavy medium method is a common gravity separation method. It uses the difference between the density of heavy medium and that of minerals to generate different buoyancy in the heavy medium, so as to achieve separation. In gravity separation of zircon titanium placer, the commonly used heavy media are magnetic separation solution, Baryte, Barium sulfate, etc.

The steps of the heavy medium method are as follows:

(1) The zirconium titanium sand ore sample is processed through crushing, screening, and other processes to obtain ore within a certain particle size range.

(2) Mix the ore sample with the heavy medium to reach a certain concentration.

(3) After stirring, standing, and other treatments, the mineral and heavy medium reach an equilibrium state.

(4) The ore samples are sorted in the gravity field, and different buoyancy is generated according to the density difference of minerals, so as to achieve separation.

2. Gravity concentrator

Gravity concentrator is a type of equipment that uses gravity field for sorting. It utilizes mechanical principles such as centrifugal force, hydraulic force, and pneumatic force to generate different trajectories of minerals in the gravity field, thus achieving separation. In the gravity separation of zirconium titanium sand ore, commonly used gravity concentrators include spiral concentrators, centrifugal concentrators, inclined plate concentrators, etc.

The steps of a gravity concentrator are as follows:

(1) The zirconium titanium sand ore sample is processed through crushing, screening, and other processes to obtain ore within a certain particle size range.

(2) The ore samples are added to the gravity concentrator, and different movement trajectories are generated in the gravity field according to the density difference of minerals, so as to realize separation.

3、 Gravity separation experiment of zirconium titanium sand ore

In order to verify the gravity separation effect of zirconium titanium sand ore, we conducted experiments.

The experimental steps are as follows:

(1) The zirconium titanium sand ore sample is processed through crushing, screening, and other processes to obtain ore within a certain particle size range.

(2) Mix the ore sample with the heavy medium to reach a certain concentration.

(3) After stirring, standing, and other treatments, the mineral and heavy medium reach an equilibrium state.

(4) The ore samples are sorted in the gravity field, and different buoyancy is generated according to the density difference of minerals, so as to achieve separation.

The experimental results show that the gravity separation method can effectively separate zirconium titanium placer ore, and the separation effect is good.

4、 The Application Prospects of Gravity Separation of Zirconium Titanium Sand Ore

Zirconium titanium placer is an important mineral resource with broad application prospects. With the continuous development of technology, the application field of zirconium titanium sand ore will continue to expand. Therefore, the gravity separation technology of zirconium titanium sand ore has important application prospects.

In summary, there are two main methods and steps for gravity separation of zirconium titanium sand ore: heavy medium method and gravity concentrator. The experimental results show that gravity separation method can effectively separate zirconium titanium sand ore, and the separation effect is good. The gravity separation technology of zirconium titanium sand ore has important application prospects.
