Binhai titanium iron sand gravity separation method

Titanium iron sand is an important metal mineral resource widely used in fields such as titanium alloys, titanium dioxide, aerospace, etc. The coastal area is an important titanium iron sand production area, but due to factors such as mixed sand and stones and high impurities, the mineral processing of titanium iron sand is relatively difficult. This article will introduce a coastal titanium iron sand gravity separation method to help everyone solve the beneficiation problem.

Characteristics of Binhai Titanium Iron Sand

Ilmenite sand in coastal areas is mainly composed of titanium Magnetite and Ilmenite, of which titanium Magnetite accounts for a large proportion. Titanium Magnetite is a magnetic mineral that can be separated by magnetic separation. However, due to factors such as mixed sand and impurities in titanium iron sand, the magnetic separation effect is not satisfactory, and other methods need to be used for re separation.

1. Gravity beneficiation method

Gravity beneficiation is a separation method that utilizes the difference of material density. In the gravity separation process of coastal titanium iron sand, the gravity beneficiation method can be used for preliminary separation. The specific operation steps are as follows:

(1) Roughly select titanium iron sand to remove larger sand particles;

(2) Place the roughly selected titanium iron sand into a gravity concentrator for separation;

(3) Separate titanium Magnetite and Ilmenite according to the density difference.

Gravity beneficiation can preliminarily separate titanium Magnetite and Ilmenite, but the separation effect is limited, and other methods need to be used for further separation.

2. Magnetic separation method

Magnetic separation is a method of separating materials by utilizing their magnetic differences. In the gravity separation process of coastal titanium iron sand, magnetic separation can be used for further separation. The specific operation steps are as follows:

(1) Place the titanium iron sand separated by gravity beneficiation method into a magnetic separator for separation;

(2) According to the magnetic difference, titanium Magnetite and Ilmenite are separated.

Magnetic separation can further separate titanium Magnetite and Ilmenite, but because there are many impurities in the ilmenite sand, the magnetic separation effect is poor, and other methods need to be used for deep separation.

3. Flotation method

Flotation method is a method of separating materials by utilizing differences in surface properties. In the gravity separation process of coastal titanium iron sand, flotation method can be used for deep separation. The specific operation steps are as follows:

(1) Place the titanium iron sand separated by magnetic separation into a flotation machine for separation;

(2) Titanic Magnetite and Ilmenite are adsorbed on the bubbles respectively through the action of reagents;

(3) Titanium Magnetite and Ilmenite are separated according to the adsorbed material on the bubble.

The flotation method can deeply separate titanium Magnetite and Ilmenite, and can remove impurities in ilmenite sand at the same time. However, the flotation method requires high equipment requirements and is difficult to operate.

3、 Conclusion

The re selection of coastal titanium iron sand is relatively difficult and requires multiple methods for separation. Gravity beneficiation, magnetic separation, and flotation are commonly used separation methods, each of which has its own advantages and disadvantages. In practical operation, it is necessary to select appropriate methods for separation based on the characteristics and beneficiation requirements of titanium iron sand.
