Mining Industry Liquid Ring Vacuum Pump & Compressors

In the mining industry, Liquid Ring Vacuum Pump & Compressors play a crucial role in various operations. These specialized systems, known for their efficiency, are employed in several key processes to enhance productivity and maintain a safe working environment.

Mineral Analysis with Vacuum Samplers: To identify the predominant minerals within a mine, vacuum samplers are utilized on ambient air and mining area walls. Extracting small rock sections, these samples undergo analysis to determine collectible minerals and guide waste management preparations.

Dust Control during Mining Operations: Mining activities generate significant dust, propelled by heavy-duty tools, large vehicles, explosions, and wind. To ensure clear visibility and breathable air, vacuum systems are applied to the surrounding area. Dust, especially from explosive mining, may contain trace amounts of desired minerals and is collected for refining. Specific vacuum setups focus on extracting crystalline silica and abrasive matter from both the air and equipment.

Vacuuming Stopes for Health and Mineral Collection: Stopes, the tunnels left post-mining, are vacuumed to manage airborne fine particulate matter and gases. This not only safeguards respiratory health from harmful materials but also facilitates the collection of desired minerals present in the dust. Vacuuming is crucial for processing or appropriate waste treatment. After blasting a stope, vacuum systems are employed to collect smaller rocks and pebbles, a process known as vamping.

In the mining industry, the use of Liquid Ring Vacuum Pump & Compressors ensures efficient and thorough extraction, contributing to both operational success and worker well-being.

Sometimes mining is done through hydraulic sluicing or alluvial mining. Hydraulic sluicing is using a high-pressure water jet to cut through minerals. Alluvial mining is the mining of stream bed deposits. These forms of mining create a lot of sludge from the sifting through water and broken-down minerals. This sludge is collected in a singular area called the sludge pit. This pit is cleaned out for further use by pumping the sludge out of the pit. The sludge may contain dissolved gasses or oils.

Waste gas that is generated from various processes in mining, such as carbon monoxide and methane, can be recovered, stored, and used in other industries. In underground mines like coal mines, methane naturally accumulates. In the lower levels of the mine, the air can be concentrated with methane.

This is dangerous for workers to breathe in, but also poses a serious risk of explosion. As a solution to this, the methane is suctioned out and oxygen from the top level is pumped in. The workers are able to breathe the oxygen and the methane is purified for use as fuel.

Below are some salient uses of liquid ring vacuum pumps in mining:

Dewatering Liquid Ring Pumps


Mining operations often encounter significant water ingress, whether from underground sources, rain, or groundwater. Liquid ring pumps are employed to remove excess water from mine shafts, tunnels, and open pits. By maintaining a dry working environment, mining operations can be carried out more efficiently and safely.

Vacuum Filtration Liquid Ring Pumps

Vacuum Filtration

In mining, various processes involve filtration to separate solids from liquids. Liquid ring pumps create vacuum pressure, which is used to facilitate the filtration process by drawing liquids through filter media. This helps recover valuable minerals and maintain the extracted materials’ purity.

Flotation Cells

In mineral processing, flotation cells separate valuable minerals from gangue materials. Liquid ring pumps play a role in creating the required vacuum for the flotation process, helping to separate and recover valuable minerals.

Dust Suppression

Mining operations can generate significant dust, which can harm workers and the environment. Liquid ring pumps are used to create a vacuum for dust collection systems, aiding in the suppression and containment of dust particles generated during excavation and transportation.


Adequate ventilation is essential in underground mining to maintain air quality and ensure the safety of miners. Liquid ring pumps can be used to create the necessary negative pressure to ensure proper airflow within the mine, reducing the risk of hazardous gas build-up.

Pumping slurries

Liquid ring pumps are capable of handling slurries, which are mixtures of solids and liquids. They can be used to pump slurry mixtures within the mining process, such as in transporting ore or waste materials.

Applications of Liquid Ring Vacuum Pumps

Liquid Ring Vacuum Pump in Mining Operations: The liquid ring vacuum pump proves indispensable in mining applications, particularly in vacuum pumping and sampling processes. Its robust design allows efficient handling of particulate solids without compromising performance.

Dust Collection and Robust Performance: This pump excels in collecting airborne dust generated during mining operations, offering a powerful vacuum at high rates. Its sturdy design requires minimal parts, facilitating easy cleaning and repair. Capable of passing solids and slurries effortlessly, the liquid ring effectively captures dust. Careful material selection ensures durability against abrasive substances, providing gentle containment within the liquid ring.

Efficient Vamping with Quick Moisture Condensation: Vamping becomes swift with the liquid ring vacuum pump, maintaining a consistently strong vacuum for efficient suction of suspended particulate matter. When water is used in stope cutting, the pump condenses moisture from the air, enhancing pumping efficiency through increased mass flow rate. This unique process results in rapid efficiency gains.

Specialization in Wet and Dirty Processes: The liquid ring vacuum pump excels in wet and dirty environments, making it ideal for sludge pit cleaning. Resilient to liquid slugs, it handles combustible gases emitted by sludge minerals, ensuring safe compression and containment with near-isothermal compression. Its explosion-proof capabilities guarantee safety in case of an explosion, preventing facility-wide spread.

Waste Gas Recovery and Corrosion Resistance: Addressing waste gas recovery in mining, the liquid ring vacuum pump, with its explosion-proofing and isothermal compression, stands out. Its corrosion resistance, crucial in moist atmospheric conditions, allows the transport of corrosive carbonic acid with minimal damage. This metallurgical resilience ensures a longer service life, making it a reliable choice in the mining industry.

In mining operations, the Liquid Ring Vacuum Pump & Compressors emerge as a versatile solution, excelling in various applications for enhanced efficiency and safety.
