Spiral chute: an efficient and eco-friendly solution for mineral re-sorting

#Industry ·2026-02-28

In the field of mineral sorting, seeking efficient, energy-saving, and environmentally friendly solutions has always been a core challenge. The spiral chute, as a classic gravity mining equipment, is an excellent answer to this challenge. With its unique physical sorting principle, it helps mineral processing enterprises achieve efficient mineral recovery and grade improvement while significantly reducing operating costs, making it an ideal choice for building green and intelligent mines. The spiral chute utilizes the layering phenomenon of different density minerals under the action of gravity, centrifugal force, friction, and water flow during the flow of mineral slurry on the spiral surface to achieve effective mineral separation. Its core advantages are as follows: - High-efficiency and precise separation: Optimized spiral surfaces and trough shapes ensure stable slurry flow, allowing heavy minerals and light minerals to stratify and enrich along their respective paths, ultimately achieving efficient and precise separation. Significantly improving the concentrate grade and recovery rate and reducing tailings loss. - Green and energy-saving model: It relies entirely on gravity for sorting, without any external power, achieving zero energy consumption operation. This not only greatly reduces production costs but also eliminates the noise and vibration pollution of traditional mechanical equipment, saving enterprises huge electricity costs and aligning with the current environmental protection concept of sustainable development. - Simple structure and stable operation: The equipment has no rotating parts, is structurally robust and durable, and has a very low failure rate. Daily maintenance is simple and convenient. Operators only need to regularly check and clean it to ensure long-term stable and reliable operation of the equipment, greatly saving maintenance time and costs. - Large processing capacity and compact footprint: A single spiral chute can handle a large amount of mineral slurry, and the equipment itself occupies a small area, effectively saving factory space and capital investment. It is suitable for all kinds of scale mining plants, especially in conditions of limited space, where its advantages are even more obvious. - Wide application and strong adaptability: It is widely used in the sorting of iron ore, tin ore, tungsten ore, tantalum-niobium ore, gold ore, coal, and various non-ferrous metals and non-metallic minerals. It has particularly good sorting effects on fine-grained minerals and is a powerful tool for processing refractory ores. Choosing a spiral chute means choosing a mature, efficient, economical, and environmentally friendly mining technology. It not only helps your mineral processing plant achieve higher economic benefits but also contributes to the construction of green mines. Upgrade your mining equipment now, and let the spiral chute become your powerful assistant in improving mineral recovery rates and concentrate grades, together opening a new chapter in mineral processing!
