A global iron ore producer needed a cutting edge solution to reduce the cost per ton of their refined ore. The major expense in iron ore processing is the cost per ton of water consumption. By eliminating the wet washing process that consists of a series of hydro-cyclones with a high volume of water usage the processing cost per ton can

The effect of a novel fluidisation arrangement on the gravity separation performance of the Reflux Classifier in upgrading ultrafine iron ore was investigated. A slow-moving rake was used to develop a strong dense medium in the lower zone of the Reflux Classifier, delivering uniform rheology and water fluidisation, and uniform discharge of the …

The Lamella High Shear Rate REFLUX™ Classifier. Iron ore - Australia. A Western Australian iron ore bulk sample (nominally -1 mm +0.106 mm) was tested using an RC™300 REFLUX™ Classifier (RC™300). The material was a sample of a resource that contained a significant amount of naturally occurring (liberated) fine iron ore (-1 mm particles).

The continuous separation of tracer particles in the air-sand dense-medium Reflux Classifier was investigated. The Reflux Classifier consisted of a 1 m long vertical fluidized bed section with a 2 m long channel inclined at 70° to the horizontal mounted above, both with a 20 × 100 mm cross section.Silica sand of 220 μm average diameter (−355 + 125 μm) was used as …

Keywords: gravity separation, Reflux Classifier, iron ore, direct reduced iron, DRI . Introduction . Recently high-grade iron ore was declared a critical mineral in Canada (Mining, 2024). This interest concerning high grade iron ore is gaining considerable traction worldwide as an enabler for producing so-called green steel.

4.2. Agitation Speed Results. We set the ore pulp concentration at 15%, the feed flux at 200 cm 3 /min, the fluidization water flux at 100 cm 3 /min, and the underflow flux at 20 cm 3 /min to investigate the influence of the …

An operational model for a spiral classifier. The processing of heavy minerals and coal is often carried out using spiral classifiers. Processing of iron ore to separate coarse iron oxides such as hematite from light gangue mineral, such as quartz, is carried out in circuits with several hundreds of rougher, cleaner and re-cleaner spirals (Bazin et al., 2014).
