Separation methods and steps of zirconium titanium sand ore

Zirconium titanium sand is an important metal mineral widely used in aerospace, shipbuilding, automotive, electronics, chemical, construction and other fields. Because the density and hardness of Ilmenite and zircon in zircon placer are similar, it is difficult to separate them. This article will introduce several methods and steps for separating zirconium titanium sand ore.

1、 Reselection method

The gravity separation method is a commonly used method for separating zirconium titanium placers. The basic principle is to use the density difference of different minerals to separate minerals by gravity separation. The specific steps are as follows:

1. Crushing: Crush the zirconium titanium sand ore to ensure its particle size meets the sorting requirements.

2. Grinding: Grind the crushed zirconium titanium sand ore to ensure its fineness meets the sorting requirements.

3. Gravity concentration: gravity concentration is carried out on the ground zircon and titanium sand ore to separate Ilmenite and zircon.

2、 Electroselection method

The electrical separation method is a method of sorting by utilizing differences in mineral conductivity. The basic principle is to utilize the different conductivity of minerals under the action of an electric field, so that they are subjected to different forces in the electric field, thereby achieving sorting. The specific steps are as follows:

1. Crushing: Crush the zirconium titanium sand ore to ensure its particle size meets the sorting requirements.

2. Grinding: Grind the crushed zirconium titanium sand ore to ensure its fineness meets the sorting requirements.

3. Electric separation: the milled zircon and titanium sand ore is electrically separated to separate Ilmenite and zircon.

III. Flotation method

The flotation method is a method of separation that utilizes the differences in surface properties of minerals. The basic principle is to utilize the difference in affinity between minerals and reagents, and through the action of bubbles, the minerals and reagents are adsorbed, thereby achieving separation. The specific steps are as follows:

1. Crushing: Crush the zirconium titanium sand ore to ensure its particle size meets the sorting requirements.

2. Grinding: Grind the crushed zirconium titanium sand ore to ensure its fineness meets the sorting requirements.

3. Flotation: Flotation the milled zircon and titanium sand ore to separate Ilmenite and zircon.

4、 Magnetic separation method

Magnetic separation is a method of separating minerals by utilizing their magnetic differences. The basic principle is to utilize the magnetic differences of minerals, and through the action of magnetic fields, the minerals are subjected to different forces, thereby achieving sorting. The specific steps are as follows:

1. Crushing: Crush the zirconium titanium sand ore to ensure its particle size meets the sorting requirements.

2. Grinding: Grind the crushed zirconium titanium sand ore to ensure its fineness meets the sorting requirements.

3. Magnetic separation: magnetic separation is carried out on the ground zircon and titanium sand ore to separate Ilmenite and zircon.

In summary, the separation methods of zirconium titanium sand ore mainly include gravity separation, electric separation, flotation, and magnetic separation. Choosing appropriate sorting methods based on different ore properties and sorting requirements can improve sorting efficiency and accuracy, reduce production costs, and achieve maximum economic benefits.
