(DOI: 10.1007/S42461-020-00343-1) Spirals, the most common equipment for the separation of heavy minerals such as chromite, are greatly affected by size distribution and the liberation degree (hence the specific gravity and size) of the feed particles. In this study, the efficiency of spirals in separation of low-grade chromite particles has been investigated by studying the …

Particle size is an essential parameter in magnetic separation [6, 34, 107, 109, 155]. Again, smaller particle size leads to higher hydrodynamic force. Hence, it is essential to have a dynamic balance between magnetic and hydrodynamic forces to capture the magnetic particles.
