· The contact angle of feldspar, quartz, and clay minerals showed an overall variation, which was shifted from water-wet to intermediate-wet under the comprehensive influence. However, after the 20 PV stage, with a substantial increase in brine phase volume, a large number of mineral surfaces resumed contact with brine.

· Abstract. Wet ultrafine grinding has been increasingly used for production of ultrafine powders in various industries. It has been known that slurry rheology significantly influences the grindability of industrial minerals in wet ultrafine grinding. This review represents some previous work with respect to slurry rheology in ultrafine grinding.

· Clay minerals can be described very simply by the stacking of two kinds of layers: 1:1 layers and 2:1 layers. They are layered by silicate in which each layer in the structure in reality consists of two sublayers. The sublayer consists of octahedral coordinates and structural water in the form of hydroxyl groups.

· Soils associated with wet and ephemerally wet environments, i.e. wet soils, cover an area greater than 12.1 million km 2; inland wetlands deliver at least Int$27.0 trillion in tangible and intangible benefits. However, due to their intimate association with wet environments, wet soils are at risk of degradation during drought events.

· In particular, the effect of wet-dry cycling may depend on the surface charge properties of dominant aluminosilicate clays. Drying can promote the acidification of highly charged clays, which may destabilize and enhance the bioavailability of mineral-associated carbon ( Clarke et al., 2011 , Kaiser et al., 2015 , Slessarev et al., 2020 ).
