2019-10-24 The first objective of Mineral Processing and Extractive Metallurgy is to remove the Mineral as soon as freed and as coarse as possible” is the first rule in treating complex ores. Ores containing two or three metals have been satisfactorily treated for a number of years. Today, however, ores containing as high as four, five and even six and seven minerals are being efficiently concentrated.

2016-1-27 Porous metalorganic frames (MOFs) have been studied in the context of a wide variety of applications, particularly in relation to molecular storage and separation sciences. Recently, we reported a green, renewable frame material composed of γ-cyclodextrin (γ-CD) and alkali metal salts—namely, CD-MOF. This porous material has been shown to facilitate the separation of mixtures
