Two-stage fast flotation of coal tailings using reflux flotation
Minerals Engineering, 2016 Abstract Low pulp density and low grade slurries in the coal and minerals industries are discharged as waste to tailings dams, incurring significant losses of valuable particles. This paper investigates the rapid processing and cleaning of hydrocyclone overflow coal slurry using two laboratory scale Reflux Flotation Cells in series as a means to ...

Green Refrontierisation: Critical Cartographies of the Hydrogen Rush in Africa
Transactions of the Institute of British Geographers, EarlyView.Short Abstract This article provides a critical cartographic analysis of the green hydrogen (GH2) maps present within the reports of European states, lobby groups and investment bodies to examine the role of geographical knowledge in the production of low‐carbon energy frontiers. It identifies three spatio‐political strategies present within these maps

Early evolutionary history of the seed
Biological Reviews, Volume 101, Issue 3, Page 1511-1553, June 2026.ABSTRACT The seed is an essential stage in the life history of gymnospermous and angiospermous plants, facilitating both their survival and dispersal. We reappraise knowledge of the evolutionary history of the gymnospermous seed, from its origin in the late Devonian through to the well‐known end‐Permian extinctions – an interval encompassing the ...

Creating Flood Disasters: Environmental Memory and Adaptation in Aotearoa New Zealand
Kōtuitui: New Zealand Journal of Social Sciences Online, Volume 21, Issue 2, June 2026.This article explores three questions. First, why does New Zealand have widespread flooding hazards? Second, why are these persistent, with little seemingly learned from the memory of earlier events? And third, beyond reiterating conventional solutions, what examples of alternatives or adaptations are being developed in different places?
