China’s LHGC–6000 vertical ring WHIMS has set new size records in magnetic separation and now acts as a benchmark for any company planning intelligent, high-capacity magnetic separation upgrades.

China’s Record-Breaking Wet High Gradient Magnetic Separator: Inside the LHGC–6000

The LHGC–6000 vertical ring wet high gradient magnetic separator is recognized as one of the world’s largest vertical ring WHIMS, with a core ring diameter of 6 meters and an equipment height of 11.8 meters. Weighing about 700 tons and designed for intelligent, continuous operation, this large-scale magnetic separator targets high-throughput hematite and quartz applications while significantly improving energy efficiency and overall plant layout.

What Is a Wet High Gradient Magnetic Separator (WHIMS)?

A wet high gradient magnetic separator is a specialized mineral processing machine designed to separate weakly magnetic minerals from non-magnetic or less magnetic material in slurry form. It uses a strong magnetic field and a finely structured matrix to capture fine particles that would escape conventional low-intensity magnetic separators.

In mining and industrial minerals, WHIMS is widely used to:

– Upgrade weakly magnetic iron ores such as hematite.

– Remove iron impurities from quartz, feldspar and other non-metallic minerals.

– Recover valuable rare earth minerals and other weakly magnetic metals.

The LHGC–6000 is a new-generation vertical ring wet high gradient magnetic separator engineered specifically for extra-large mining and mineral processing projects. With its 6 meter ring diameter and 11.8 meter total height, it sets new size benchmarks in the WHIMS category and targets operations handling tens of millions of tons of ore per year.

Key Technical Specifications

The LHGC–6000 vertical ring WHIMS stands out with the following core parameters:

– Ring diameter: 6 m

– Equipment height: 11.8 m

– Total weight: 700 t

– Background magnetic field strength: up to approximately 1.8 T

– Processing capacity: up to 1,300 t/h for hematite, up to 800 t/h for quartz sand

– Energy consumption: reduced by more than 60 percent per ton of ore processed versus a 3 m vertical ring high-gradient magnetic separator

– Engineering investment: more than 30 percent savings in plant investment per ton of ore output

These figures position the LHGC–6000 as a flagship solution for high-volume processing plants seeking to optimize both capital and operating expenditure.

Performance Advantages: Capacity, Energy Efficiency and Footprint

Modern mines demand equipment that can process more ore with less energy and a smaller footprint. The LHGC–6000 vertical ring wet high gradient magnetic separator is designed specifically around these performance indicators.

High Throughput and Process Intensification

Compared with a 3 meter vertical ring high-gradient magnetic separator, the LHGC–6000 can deliver up to eight times the throughput, reaching 1,300 tons per hour for hematite and 800 tons per hour for quartz sand. This allows operators to consolidate multiple smaller separators into a single large unit, simplifying piping, feeding systems and automation while increasing overall plant productivity.

Energy Savings and Cost Reduction

By improving coil design, magnetic circuit efficiency and process configuration, this large-scale WHIMS can cut energy consumption per ton of ore by more than 60 percent. Combined with a simplified process layout and reduced occupied area per ton of output, plants can achieve more than 30 percent savings in engineering investment for large-scale projects.

Compact Layout and Engineering Benefits

Despite its physical size, the large ring WHIMS design enables a compact process layout when evaluated per ton of ore processed. Fewer units, simpler foundations and reduced auxiliary infrastructure help operators design more streamlined magnetic separation circuits in both greenfield and brownfield projects.

Intelligent Design: Cooling, Modularity and Automation

Beyond size, the LHGC–6000 integrates multiple intelligent magnetic separation technologies that address thermal management, installation challenges and predictive maintenance requirements.

Advanced Coil Cooling and Modular Structure

The excitation coil uses an oil-cooled external circulation system that increases heat dissipation capacity and protects coil insulation at high duty cycles. Oversized components such as the vertical ring are designed with a split, modular structure, making transportation, hoisting and on-site installation more manageable even in remote locations.

Automation, Sensing and Remote Management

The LHGC–6000 incorporates several layers of automation and digital control, including:

– Automatic slurry level adjustment.

– Automatic centralized lubrication.

– Real-time pressure and temperature monitoring.

– Intelligent alarms for critical operating parameters.

The separator also integrates Internet of Things and big data analysis technologies to enable remote operation, remote fault diagnosis and full lifecycle management. This combination helps operators reduce unplanned downtime, extend component life and standardize maintenance practices across multiple sites.

Application Scope: From Hematite to High-Purity Quartz

The LHGC–6000 vertical ring wet high gradient magnetic separator is designed for a wide range of weakly magnetic minerals and impurity removal tasks in both metallic and non-metallic applications.

Weakly Magnetic Metal Minerals

This separator targets a variety of weakly magnetic minerals, including:

– Iron oxides such as hematite and similar ores.

– Titanium-bearing minerals.

– Manganese ores.

– Chromium-bearing minerals.

– Cobalt and other strategic metal minerals.

– Rare earth minerals.

For these applications, high gradient and strong background fields help capture fine-grained, low-intensity magnetic particles that would be lost in conventional magnetic circuits.

Non-Metallic Minerals and Iron Removal

In industrial minerals, large-scale WHIMS equipment is widely used to remove iron and other magnetic impurities from non-metallic feedstocks. The LHGC–6000 can be deployed in:

– Quartz and high-purity quartz sand.

– Feldspar and ceramic raw materials.

– Other non-metallic minerals requiring tight Fe₂O₃ control.

By effectively lowering iron content, operators can upgrade product quality for glass, ceramics and advanced materials, aligning with increasingly stringent downstream specifications.

Technical Breakthroughs Behind the LHGC–6000

Huate’s research and development teams spent considerable time and effort solving multiple bottleneck technologies to make the LHGC–6000 feasible at commercial scale. These breakthroughs are important for any operator considering the transition from conventional WHIMS to extra-large intelligent systems.

Overcoming Large-Scale Thermal Management Challenges

One major bottleneck was heat dissipation in large-scale excitation coils, where high currents and long duty cycles create significant thermal loads. By adopting an oil-cooled external circulation system and optimizing coil design, the separator achieves stable magnetic field strength and safe, reliable performance during continuous high-capacity operation.

Transporting and Installing Oversized Components

Another challenge involved transporting and erecting oversized and heavy components, including the 6 meter vertical ring.

Strategic Benefits for Large-Scale Mining and Processing Plants

For large mines and processing plants, moving to extra-large intelligent WHIMS equipment can deliver strategic benefits that go beyond immediate energy and labor savings.

Scale-Up for Tens of Millions of Tons per Year

The LHGC–6000 is specifically designed to meet the needs of mining enterprises with outputs measured in tens of millions of tons per year. Higher unit capacity enables simpler circuit design, fewer items of major equipment to operate and maintain, and smoother integration with upstream crushing and grinding and downstream dewatering and tailings management.
