Spiral chute: a green and efficient method of selecting high-quality minerals through re-concentration

#Industry ·2026-02-18

In today's world where mineral resources are becoming increasingly scarce and beneficiation technologies are constantly evolving, how to extract valuable minerals from ores in a more efficient and environmentally friendly manner has become a common challenge in the mining industry. The spiral chute, as a classic and highly efficient gravity beneficiation equipment, plays an irreplaceable role in the sorting of various minerals with its unique structure and working principle, making it an ideal choice for improving beneficiation efficiency and achieving green production. 【Working Principle: Natural Force, Precise Sorting】 The spiral chute does not require power. It relies solely on the weight of the slurry, the force of water flow, and the friction and density differences between particles to achieve effective mineral separation. When the slurry enters the feeding port at the top of the chute, it flows down along the spiral groove. Under the combined action of centrifugal force, gravity, and water flow, the heavy minerals with higher density will settle and gradually move towards the inner spiral path, while the light minerals with lower density will be carried by the water flow towards the outer spiral path, ultimately being collected through different discharge ports, thus achieving precise grading and efficient enrichment. 【Core Advantages: Multiple Values, Created for You】 High efficiency and energy saving, low operating costs: The unique design of the spiral chute ensures high recovery rates and enrichment ratios, while its non-powered working principle almost achieves zero energy consumption, greatly reducing production costs and electricity expenses. Simple structure, easy maintenance: The equipment has no moving parts, compact structure, and extremely low failure rate. Daily maintenance work is minimal, effectively reducing downtime and repair costs. Environmentally friendly and pollution-free, in line with green concepts: It mainly sorts minerals using water as the medium, without adding chemical reagents, which is environmentally friendly and fully meets the requirements of modern mining for green and environmentally friendly production. Wide applicability and stable performance: It has significant sorting effects on various medium- and fine-grained minerals such as iron ore, tin ore, tungsten ore, tantalum-niobium ore, gold ore, and coal sludge. The equipment operates stably and reliably, with minimal impact from environmental factors. Small footprint and quick return on investment: The compact structure design effectively saves site space. Combined with its high efficiency and low cost, the return on investment period is significantly shortened. 【Application Fields: Wide Coverage, Maximizing Value】 The spiral chute is widely used in beneficiation plants for ferrous metals, non-ferrous metals, rare metals, and non-metallic minerals, and is particularly suitable for processing minerals with a particle size ranging from 0.02 to 3 mm, making it an ideal equipment for sand mining, tailings re-sorting, and concentrate enrichment. Choosing the spiral chute means choosing a mature, efficient, and environmentally friendly beneficiation solution.
