Quartz ore is an important non-metallic mineral. It is primarily composed of silicon dioxide (SiO₂). High-purity quartz is a key raw material in industries like glass, ceramics, photovoltaics, and semiconductors and so on. Natural quartz ore often contains impurities such as iron, aluminum, mica, and feldspar, these impurities affect quality and usability of quartz sand. Mineral processing is essential technology to purify quartz ore. The selection and efficiency of quartz sand mineral processing equipment directly impact purification results and product costs. This article will introduce the types and selection of quartz ore processing equipment.
Quartz sand beneficiation process usually includes crushing, grinding, magnetic separation, flotation, gravity separation, acid leaching and other links. The corresponding beneficiation equipment is as follows:
Quartz ore dressing: Crushing equipment
Common quartz ore crushing equipment includes jaw crusher and cone crusher. Their working principles, applications and characteristics are as follows:
1. Jaw crusher
-Working principle: The jaw crusher adopts the flexural extrusion crushing method. The movable jaw plate makes periodic movements on the fixed jaw plate to squeeze the ore and crush it.
-Application: The jaw crusher is mainly used for the primary crushing of quartz ore and is suitable for processing ore with larger particle size (>150mm).
-Features: The jaw crusher has the characteristics of simple structure, durability and strong adaptability. It can handle high-hardness ores.
2. Cone crusher
-Working principle: The cone crusher rotates the eccentric shaft to make the crushing wall and the mortar wall approach and move away continuously, so as to achieve the purpose of squeezing and crushing the ore.
-Application: The cone crusher can be applied to the medium and fine crushing process. The crushing equipment can effectively control the discharge particle size during the process and improve the subsequent grinding efficiency.
-Features: Cone crusher has the characteristics of large crushing ratio, strong production capacity and low energy consumption, and it can be suitable for large-scale production.
Quartz ore dressing: Grinding equipment
The grinding equipment of quartz ore are ball mill and stirred mill. The followings are their working principles, applications and characteristics:
1. Ball mill
-Working principle: The quartz ores are impacted and ground by media such as steel balls or ceramic balls in the rotating cylinder, and gradually crushed to the particle size required for subsequent mineral beneficiation.
-Application: Ball mill is used in the fine grinding process of quartz ore, and it can also be widely used in wet grinding process.
-Features: It has a wide range of applications and can be used for dry or wet grinding, and the particle size of the output is controllable.
2. Stirred mill
-Working principle: The effect of the stirred mill on the material is to use a high-speed rotating agitator to drive the quartz sand to interact with the grinding medium (such as zirconia balls) to achieve the effect of ultra-fine grinding.
-Application: Stirred mill can be used for ultra-fine grinding of high-purity quartz ore. It can also reduce the particle size to micrometer or nanometer level.
-Features: The stirred mill has the advantages of low energy consumption and high grinding efficiency, therefore it is particularly suitable for the preparation of ultra-fine powders.
Quartz ore dressing: Magnetic separation equipment
The types of magnetic separation equipment used in quartz ore dressing include wet magnetic separators and high gradient magnetic separators. The specific contents are as follows:
1. Working principle of wet magnetic separator: Ore reacts differently in different magnetic fields. The magnetic field is used to separate the hematite and magnetite in the ore, thereby improving the purity of the quartz ore. Wet magnetic separators can be used to remove iron impurities in quartz sand and increase the content of silicon dioxide in the ore. Because wet magnetic separators have the advantages of large processing capacity and high sorting efficiency, they are widely used in the roughing and concentrating stages of quartz ore.
2. Working principle of high gradient magnetic separator: Using strong magnetic fields and fine magnetic media to remove extremely fine iron impurities, this equipment is used for the processing of high-purity quartz. It has the advantage of high sorting accuracy.
Development of Quartz Ore Dressing Equipment
With the continuous advancement of mineral processing technology, quartz ore dressing equipment is gradually moving towards automation and intelligence. Making good use of the automation of mineral processing equipment can effectively improve the efficiency of mineral processing and reduce labor costs. In the magnetic separation process, it is equipped with automatic detection of iron impurity content and real-time adjustment of magnetic field strength. Flotation equipment equipped with automation and monitoring equipment can observe the generation of foam in real time and control the amount of flotation reagents. In addition, the use of dry mineral processing technology and energy-saving crushing and grinding equipment can also reduce resource consumption and waste discharge.
As mentioned above, there are many types of quartz ore dressing equipment. The selection of specific equipment needs to be based on the ore properties of the quartz ore, the beneficiation requirements and the production budget. Reasonable beneficiation technology and equipment are of great significance to improving the purity of quartz ore, reducing production costs and improving economic benefits.
