Do Incineration Slag Treatment Plants Need Gravity Separation Equipment?

Smelting Slag Metal Recycling /

In incineration slag treatment projects, questions about gravity separation equipment are frequently raised during process design. Jig machines and shaking tables are traditionally associated with mineral processing, so it is natural for project owners and engineers to ask whether these devices are truly necessary for slag treatment—or if magnetic separation alone is sufficient. The answer […]

Operating a Shaking Table Successfully: Practical Methods to Improve Gravity Separation Performance

News /

In gravity separation of fine and medium-sized heavy minerals, the shaking table remains one of the most effective tools when separation accuracy matters more than throughput. However, the performance of a shaking table depends far more on how it is operated than on the machine itself. Many plants install shaking tables but fail to achieve

Magnetic Separation in Metal Recovery from Waste Incineration Slag

Smelting Slag Metal Recycling, Solutions /

Metal recovery is one of the core objectives in the resource utilization of municipal solid waste incineration slag. Incineration slag typically contains a considerable amount of metal components, ranging from large iron pieces to fine iron powder. If these metal materials are not effectively recovered, they not only result in resource losses but may also

The Role of Trommel Screens in Incineration Slag Classification and Treatment

Smelting Slag Metal Recycling /

Incineration slag treatment is a complex process that involves handling highly heterogeneous materials. Unlike natural ores or construction aggregates, incineration slag contains a wide range of particle sizes, irregular shapes, residual metals, mineral fragments, and unburned residues. Effective classification at the early stages of processing is therefore essential for ensuring stable operation and high recovery

Shaking Table Separation: Why It Remains Essential for Fine Gravity Beneficiation

Ferrous Metal Ore Beneficiation, News /

When processing high-density minerals such as tin, tungsten, and tantalum–niobium ores, mineral processing plants often prioritize stable recovery, clear separation, and controllable operating costs over maximum throughput. As ore grades decline and valuable minerals become increasingly fine-grained, plants must recover fine heavy particles more reliably than ever before. For this reason, the shaking table continues

How Incineration Slag Is Formed and Converted into Reusable Eco-Friendly Materials

Smelting Slag Metal Recycling, Solutions /

At a certain moment each day, municipal sanitation workers collect household waste in an orderly manner and transport it by garbage trucks to municipal waste-to-energy incineration plants. When mechanical arms feed various types of household waste into the incinerator, incineration slag gradually takes shape. As the final residue of the waste incineration process, slag becomes

Incineration Slag Treatment for Resource Recovery

Smelting Slag Metal Recycling /

Municipal solid waste incineration generates a large volume of incineration slag containing ferrous metals, non-ferrous metals, and mineral aggregates. Without proper treatment, this material places long-term pressure on landfill capacity and environmental compliance. With appropriate processing and separation technologies, incineration slag can be transformed into valuable recyclable resources and eco-friendly construction materials. We provide complete

Optimize Your Barite-Fluorite Processing: Gravity-Flotation Separation

News /

The Chongqing (China) is rich in barite-fluorite associated ore resources. These ores are characterized by a strong intergrowth between barite and fluorite, making their separation challenging. Barite and fluorite are often found intertwined, as aggregates, or even as inclusions within one another. Some gangue minerals, such as calcite and quartz, further complicate the process of achieving
