The electrostatic separation technique is generally utilized for recycling metallic materials from electronic waste [1,2,3,4,5,6].This dry separation technology is also successfully employed in mineral processing [7,8,9,10] and the food industry [11, 12].As a perfectly dry method, electrostatic separation is an environmentally friendly technique …

Wolframite mineral processing method mainly in gravity separation, and includes four parts: pre-selection, gravity separation, concentration and recovery. By pre-selection and discarding the waste rock which accounts for 50% of the raw ore, the WO3 grade of the ore is enriched from 0.25% ~ 0.3% to 0.45% ~ 0.8 %, and the recovery is …

The need for the research into the tribo-electrostatic separation of South African high ash coal had increased significantly due to the depletion in the reserves of high grade coal, increase in SOX and NOX generation of low grade coal and increase in the South African power utility's coal burn rate. Wet coal beneficiation techniques have been reported for …

The potential of electrostatic separation in the upgrading of South African fine coal prior to utilization a review

This study concentrated on the adsorption features and mechanism of a novel amidoxime surfactant 3-dodecylamine propyl amidoxime (DPA) used as a new wolframite collector on wolframite and calcite surfaces. The flotation experiment showed that DPA collector has a remarkable flotation separation effect on wolframite and calcite. Additionally, the results …

Abstract. Wolframite is often associated with calcium bearing minerals, leading to low grade, while conventional anionic collectors are hard to realize their efficient flotation separation, thus the effective structural modification of cationic collectors provides a new insight into enhancing the comprehensive development of wolframite resources.
