Advances in Separation and Purification Techniques

Dear Colleagues,

With the increasing demand for environmental measures such as SDGs (sustainability development goals) and carbon neutrality, the importance of supplying a safe and stable resource supply is increasing. Efficient and highly accurate separation and purification technologies are indispensable for recovering useful resources with a low environmental load from difficult-to-treat ores and spent materials. In addition, effective separation technology for wastewater and exhaust gas generated in various resource refining processes is also indispensable. To accomplish them, we need the best mix of physical, physicochemical, and chemical separation technologies. It is also important to develop innovative separation technologies based on new ideas.

This Special Issue invites a wide range of research topics on innovative separation and purification technologies for utilizing unused resources and spent materials and environmental purification.

We investigated the influence of microwave and conventional heating pretreatments on the grinding of cassiterite associated with pollimetallic ore. The minerals that exhibited a stronger microwave absorption ability crushed first, which is the main difference between the microwave and the traditional heating pretreatments. The distribution of Fe, Pb, Zn, and Sn increased in the fine size range (−0.425 mm). The Fe and Pb grades in the size ranges of −3.2 + 2 mm and −2 + 1 mm after the microwave pretreatment (6 kW, 1 min) were lower than those of the traditional heating (12 kW, 400 °C, 20 min), indicating that the microwave selective heating was beneficial for pyrite and jamesonite. The grade and distribution of Sn decreased significantly in the size ranges of −3.2 + 2 mm and −2 + 1 mm and increased in the size ranges of −0.425 + 0.15 mm and −0.15 + 0.074 mm. Microwave heating treatment promoted the grinding of sulfide ore and reduced the cassiterite overgrinding. Full article
