The spiral separator is suitable for processing alluvial gold ore, especially for gold ore with a high degree of monomer dissociation and flat shape. Besides, it is also good at dealing with fine gold ore with particle sizes between 0.003-0.6mm containing low mud content. Spiral chutes are often used for rough concentration. What we love:
