Environmental Impact of Silicic Magmatism in Large Igneous Province Events
Geophysical Monograph Series, Page 133-151., 2021 Exploring the links between Large Igneous Provinces and dramatic environmental impact
An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Coal desulfurization by flotation method
IOP Conference Series: Earth and Environmental Science, 2023 Abstract In general, the combustion of coal containing high sulfur and ash causes negative environmental problems such as acid rain and the emission of oxides of sulfur. Coal flotation is one of the most effective methods for desulfurizing and deashing raw coal with high ash and sulfur contents before burning coal.

An investigation of the effect of clay type on coal flotation along with DLVO theoretical analyses [PDF]
, 2019 Coals generally exist with clay minerals, which are very fine-sized minerals, and adversely affect the flotation of coal. For instance, they make the coal surface hydrophilic by coating coal surfaces and therefore, they inhibit bubble-particle attachment.
