Case study: high capacity spiral J concentrators

Concentrator plants are usually sized to a predetermined output and grade of mineral concentrate. Thus, the feed grade, determines the size of concentrator plants Traditional spiral concentrators such as the MG4 can operate in the range of 1.6 to 2.6 t/h (solids) at 35% solids by mass in slurry feed. In contrast high capacity spiral concentrators
