Problems solved by technology

[0002] The traditional method of dry separation of natural rutile and zircon sand is: electric separation and magnetic separation are separated by a single machine, and the transportation of minerals is manually pulled by a bucket truck, which is time-consuming, labor-intensive, labor-intensive, and low-yield.
At the same time, because the flow of minerals is unstable, the technical parameters of the electric separator and magnetic separator also need to be adjusted frequently. Frequent adjustment of parameters affects the unstable and uneven quality of the product.

Embodiment 1

[0019] The dry Pakistani zircon sand medium ore with a zirconia content of 50% is selected as the raw material. The chemical composition before treatment:

[0020]

[0021] Follow the steps below.

[0022] 1. Weak magnetic separation:

[0023] Put the zircon sand medium ore into the weak magnetic separator with three magnetic rollers through the hoist for magnetic separation and separation. The magnetic field strength of each magnetic roller is 800GS, 8000GS, 13000 GS respectively, and the magnetic roller speed is 400 rpm; The magnetic material ilmenite and so on are separated. Zircon sand, which is a non-magnetic material, enters the next process.

[0024] 2. The first level of electric selection:

[0025] Put the zircon sand medium ore after weak magnetic separation into the 22,000-volt first high-pressure four-roller electric separator through the hoist for electric separation and separation, the roller speed is 780 rpm, and the sand ore heating temperature is 70°C; ...

Embodiment 2

[0041] Dry Pakistani zircon middling ore with a zirconia content of 52% was selected as the raw material.

[0042] Chemical composition before treatment:

[0043]

[0044] The dry separation method is the same as in Example 1. After inspection and analysis, the technical indicators of the zircon sand concentrate product at the 1# sampling point:

[0045]

[0046] Technical indicators of zircon sand concentrate products at 2# sampling point:

[0047]

[0048] It can be seen from the above indicators that the quality of the zircon sand product produced by the method is stable and evenly conforms to the national standard.

Embodiment 3

[0050] Dry Pakistani zircon middling ore with a zirconia content of 50.5% is selected as the raw material.

[0051] Chemical composition before treatment:

[0052]

[0053] The processing method is the same as that of Example 1. After inspection and analysis, the technical indicators of the 1# sampling point zircon sand concentrate product:

[0054]

[0055] Technical indicators of zircon sand concentrate products at 2# sampling point:

[0056]

[0057] It can be seen from the above indicators that the quality of the zircon sand product produced by the method is stable and evenly conforms to the national standard.

Abstract

The invention discloses a natural rutile or zircon sand dry separation production method which sequentially comprises a first-stage electric separation, a second-stage electric separation, a third-stage electric separation, high-voltage arc plate electric separation and strong magnetic separation to obtain zircon sand concentrate or natural rutile concentrate. According to the invention, the production technology is simplified, the production efficiency is greatly improved, the labor strength is lowered, and uniform and stable product quality can be ensured.

Description

technical field [0001] The invention relates to a production method of dry separation of titanium-zirconite, in particular to a production method of dry separation of natural rutile or zircon sand. Background technique [0002] The traditional method of dry separation of natural rutile and zircon sand is: electric separation and magnetic separation are separated by a single machine, and the transportation of minerals is manually pulled by bucket trucks, which is time-consuming, labor-intensive, labor-intensive, and low-yield. At the same time, due to the unstable flow of minerals, the technical parameters of the electric separator and magnetic separator also need to be adjusted frequently. Frequent adjustment of parameters affects the unstable and uneven quality of the product. Contents of the invention [0003] The purpose of the present invention is to provide a production method for dry selection of natural rutile or zircon sand with stable quality and high uniformity. ...
