Zirconium titanium sand is an important metal mineral resource, mainly used for manufacturing high-strength, wear-resistant, corrosion-resistant metal alloys, ceramics, and optical glass materials. Pre selection and enrichment are very important steps in the mining and processing of zirconium titanium sand. This article will introduce a pre selection and enrichment plan for zirconium titanium sand, hoping to be helpful to zirconium titanium sand processing enterprises.
1、 Preconcentration and Enrichment Principle of Zirconium Titanium Sand
Zirconium titanium sand mainly contains zircon ore and Ilmenite, and the density difference between the two is large, so it can be preconcentrated and enriched by heavy medium separation. The principle of heavy medium separation is to use the density difference of different minerals to separate minerals under the action of heavy medium. In the preconcentration and enrichment process of zirconium titanium sand, the heavy medium usually used is magnetic separation tailings or Baryte.
2、 Pre selection and enrichment plan for zirconium titanium sand
1. Magnetic separation tailings heavy medium separation method
The main steps of this method are:
(1) The zirconium titanium sand ore is subjected to crushing, screening, magnetic separation and other processes to obtain magnetic separation tailings.
(2) Mix magnetic separation tailings with water to form a heavy medium.
(3) The heavy medium is injected into the separator to separate zircon ore and Ilmenite through the action of vibration and water flow.
(4) The separated zircon ore and Ilmenite are respectively dried, ground, magnetic separation and other processes to obtain preconcentration and enrichment products of zircon and titanium sand.
2. Baryte heavy medium separation method
The main steps of this method are:
(1) The zirconium titanium sand ore is subjected to crushing, screening, and other processes to obtain rough beneficiation.
(2) Mix rough beneficiation with water to produce a heavy medium.
(3) The heavy medium is injected into the separator to separate zircon ore and Ilmenite through the action of vibration and water flow.
(4) The separated zircon ore and Ilmenite are respectively dried, ground, magnetic separation and other processes to obtain preconcentration and enrichment products of zircon and titanium sand.
3、 Advantages and Disadvantages of Preconcentration and Enrichment Schemes for Zirconium Titanium Sand
The advantage of magnetic separation tailings heavy medium separation method is that it can utilize magnetic separation tailings and reduce resource waste; The disadvantage is that the tailings from magnetic separation contain certain magnetic substances, which may affect the sorting effect.
2. The advantage of Baryte heavy medium separation method is that the separation effect is good, and high grade preconcentrated and enriched products can be obtained; The disadvantage is that additional Baryte needs to be purchased as the heavy medium, and the cost is high.
4、 Conclusion
Pre selection and enrichment of zirconium titanium sand is a very important step in the processing of zirconium titanium sand. This paper introduces two preconcentration and enrichment schemes of zircon and titanium sand, which are magnetic separation tailings heavy medium separation method and Baryte heavy medium separation method. Both options have their own advantages and disadvantages, and enterprises can choose the one that suits them according to their own situation.
