Experiment on rough selection of zirconium titanium sand

Zirconium titanium sand is an important mineral resource with a wide range of applications, including construction, electronics, aerospace and other industries. In the processing of zirconium titanium sand, rough selection is a very important step, as it directly affects the subsequent beneficiation work. This article will introduce the operating steps and precautions for the rough selection experiment of zirconium titanium sand.

1. Experimental equipment and reagents

1. Experimental equipment: magnetic separator, vibrating screen, electronic balance, magnetometer, microscope, etc.

2. Reagents: sodium hydroxide, sulfuric acid, hydrochloric acid, methanol, ethanol, phenol, etc.

2、 Experimental steps

1. Sample preparation

Grind the zirconium titanium sand sample into powder and obtain a sample with a particle size between 0.074mm and 0.2mm through sieving.

2. Pre processing

Wash the sample with a mixture of methanol and ethanol to remove surface impurities and organic matter.

3. Magnetic separation

Place the washed sample into a magnetic separator for magnetic separation. The magnetic field strength and separation time of the magnetic separator need to be adjusted according to the actual situation. After magnetic separation, the magnetic separation products are vibrated and screened to obtain magnetic separation concentrate and tailings.

4. Reselection

The magnetic separation concentrate and magnetic separation tailings are gravity separated with hydrochloric acid and sodium hydroxide respectively. The purpose of gravity separation is to remove impurities such as iron and aluminum from magnetic concentrate and tailings. After the gravity separation, the products are subjected to vibration screening to obtain the gravity concentrate and tailings.

5. Post processing

Float the gravity concentrate with phenol to obtain a zirconium titanium sand coarse concentrate. The content of titanium and zirconium in the rough concentrate needs to be determined through chemical analysis.

3、 Precautions

1. During sample preparation and pre-treatment, it is necessary to avoid contamination of the sample.

2. The magnetic field strength and magnetic separation time of the magnetic separator need to be adjusted according to the actual situation to ensure the magnetic separation effect.

3. The dosage of sodium hydroxide and hydrochloric acid shall be controlled during gravity concentration to avoid excessive waste liquid.

4. During the post-treatment process, attention should be paid to the dosage of phenol and flotation time to ensure the production of high-quality zirconium titanium sand roughing concentrate.

In summary, the rough selection experiment of zirconium titanium sand is a very important step in the process of zirconium titanium sand processing, and it is necessary to strictly follow the operating steps to ensure the obtaining of high-quality zirconium titanium sand rough selection concentrate.
