Spiral chute: a smart choice for gravity concentration mining

#Industry ·2026-02-04

In the vast field of mineral processing and beneficiation, how to achieve precise separation of minerals in an efficient, economical, and environmentally friendly manner has always been a core goal pursued by the industry. Among numerous beneficiation equipment, spiral chutes stand out with their unique gravity separation principle and excellent performance, becoming an ideal device for sand mining and fine-grained mineral separation, as well as a wise choice for building green and intelligent mines. Spiral chutes, this classic gravity beneficiation equipment, do not rely on complex mechanical power, but cleverly utilize the process of mineral slurry flowing in the spiral trough to naturally stratify and separate non-similar weight mineral particles under the combined action of gravity, water flow, and friction. Its core advantages include: 【Core Advantages】 1. High-Efficiency Separation with High Recovery Rate: The unique spiral curved design ensures that the mineral slurry forms a stable laminar flow in the trough, allowing light and heavy mineral particles sufficient time and space for thorough separation. This is particularly effective in recovering fine-grained minerals (such as micro-gold, tin, chromium, ilmenite, zircon, etc.), significantly improving the concentrate grade and recovery rate. 2. Energy-Efficient and Environmentally Friendly, a Green Future: The spiral chute operates without additional power, completing the separation solely through gravity, greatly saving energy consumption. At the same time, the entire process does not use any chemical reagents, avoiding secondary pollution and fully meeting the stringent requirements of modern mines for green and environmentally friendly production, serving as a cornerstone for building a sustainable mining industry. 3. Simple Structure and Convenient Maintenance: The equipment has no moving parts and a very simple structure, which not only greatly reduces equipment failure rates but also makes daily maintenance extremely easy, requiring almost no additional maintenance costs. The trough made of wear-resistant materials ensures the equipment's durability and long service life. 4. User-Friendly Operation and High Adaptability: The installation, commissioning, and operation of the equipment are very simple and intuitive, allowing even non-professional technicians to easily get started. It can adapt to different particle sizes, different grades, and different types of mineral separation, with a wide range of applications. Whether it's sand gold, iron ore, chromite, titanium iron ore, rare metals, or non-metallic minerals, it can always be found playing an efficient role. 5. Small Footprint and Low Investment Cost: Compared with other large-scale beneficiation equipment, spiral chutes occupy a small area, effectively saving production space. More importantly, their initial investment cost is relatively low, helping mining enterprises effectively control project budgets while ensuring separation efficiency and achieving higher return on investment. 【Application Fields】 Spiral chutes are widely used in the beneficiation of gold, iron, titanium iron, chromium, tin, tungsten, tantalum-niobium, zircon, rutile, and other non-ferrous and non-metallic minerals, particularly excelling in the separation of beach, riverbed, and alluvial deposits. Choosing a spiral chute is choosing an efficient, environmentally friendly, economical, and reliable solution for mineral separation. It's not just a piece of equipment, but also a powerful booster for mining enterprises to achieve sustainable development, improve economic efficiency, and embrace green concepts. If you are looking for a separation equipment that can significantly improve separation efficiency, reduce operating costs, and meet environmental standards, then a spiral chute is undoubtedly your ideal choice.
