Even Humphrey spiral concentrator reduced the feed to 35.4 wt%, the recovery rate was very low. When the fine aggregate waste was not recirculated, the recovery rate of zircon was 57.03%, monazite 48.79%, ilmenite 35.76%, and magnetite 26.55%. Nevertheless, recirculation of the middlings increased the concentrate to 36.9% …

Spiral Concentrator

spiral concentrators are used in most applications, particularly for concentrating low-grade ores. Manufactured from lightweight, corrosion and abrasion-resistant materials, our spirals require minimal maintenance and upkeep. Gives you an effective and low-cost solution for gravity separation. Reduces maintenance with a durable design.
