DOVE supplies the largest range of Dewatering Screens, in 9 standard models, with capacity range of (10 – 200) Tons/ Hour, with widths from 1200 –2500 mm (47.24 -98.42 Inch) wide, and 3000-4500 mm (118.11-177.16 Inch) long.
The REFLUX™ Classifier is a recently developed water-based gravity separation technology that is already being used worldwide to beneficiate particles above 0.100 mm in size. This paper reports tests performed on an ultra-fine iron ore with nominal top size of 0.106 mm, but with 59 wt-% being below 0.038 mm in size.
Iron ore tailings (IOTs) are an important solid waste in the mining industry, which can pollute the environment and endanger human health. However, the disposal and high value-added utilization of iron tailings have always been a challenge. Notably, superconducting high-gradient magnetic separation (S-HGMS) technology is a promising technology in mineral …
