The development of sustainable supplies of critical minerals and metals is required if society is to succeed in the decarbonisation of the global economy. While the discovery of critical metal deposits is urgent, of equal importance is understanding the life cycle of critical metals that are already in the economy. This book includes ten empirical studies on both the discovery and investigations of the life cycle of critical metals. A wide range of critical metals in the hydrothermal system, including Co, Ga, Ge, Re, REEs, In, Sb, Sn and W, were investigated by researchers from China, Australia, North America and Europe. These studies present an advanced understanding of the genesis of global critical metal resources, by utilising traditional and non-traditional analytical approaches. This book also promotes the green mining concept. Innovative technological development that allows extracting additional critical metals from current production and from historic mine wastes is reported. Academics and practitioners will find, in this book, very recent case studies of geochemistry, mineralogy, geometallurgy and the exploration of critical metals in various hydrothermal systems, as well as the major challenges and opportunities facing academic research and industrial mineral exploration.

During the last decade, software developments in Scanning Electron Microscopy (SEM) provoked a notable increase of applications to the study of solid matter. The mineral liberation analysis (MLA) of processed metal ores was an important drive for innovations that led to QEMSCAN, MLA and other software platforms. These combine the assessment of the backscattered electron (BSE) image to the directed steering of the electron beam for energy dispersive spectroscopy (EDS) to automated mineralogy. However, despite a wide distribution of SEM instruments in material research and industry, the potential of SEM automated mineralogy is still under-utilised. The characterisation of primary ores, and the optimisation of comminution, flotation, mineral concentration and metallurgical processes in the mining industry by generating quantified data, is still the major application field of SEM automated mineralogy. However, there is interesting potential beyond these classical fields of geometallurgy and metal ore fingerprinting. Slags, pottery and artefacts can be studied in an archeological context for the recognition of provenance and trade pathways; soil, and solid particles of all kinds, are objects in forensic science. SEM automated mineralogy allows new insight in the fields of process chemistry and recycling technology.

Met als ondertitel 'Versjes over de aard van het beestje' worden 16 vergelijkingen gemaakt tussen dieren met een tegengestelde eigenschap, zoals netjes-slordig, volgzaam-dwars, onaardig-aardig, geduldig-rusteloos of bazig-verlegen. De duo's lijken op elkaar, maar zijn ook elkaars tegenpolen, zoals de voorzichtige alpenmarmot en de onbesuisde eekhoorn of de krachtige eland en de kwetsbare ree. Meervoudig Gouden Griffel-winnaar Bette Westera weet het karakter raak te treffen door de dieren zelf te laten vertellen wat ze doen en waar ze van houden. De gedichten zijn grappig en heel herkenbaar, zoals de twee titelgedichten 'Braaf' en 'Stout'. De ik-vorm van de gedichten werkt als een spiegel voor de lezer. Mies van Hout vult de kleurenillustraties aan met treffende kleuren, gezichtsuitdrukkingen en houdingen. In wisselende technieken met collages, krijt of verf krijgt ieder duo een eigen sfeer en invulling. Een prentenboek om samen over te praten en jezelf in te herkennen. Heel geschikt voor het gebruik in de klas voor alle leeftijden. Poëzieprentenboek in oblong formaat met 32 gedichtjes, vanaf ca. 4 t/m 8 jaar.Loes Reichenfeld.NBD BiblionWat een heerlijk innemend prentenboek is ?Brave hond! Stoute kat!??! Het concept is al even eenvoudig als origineel: in telkens twee versjes over twee verschillende dieren worden contrasterende eigenschappen in beeld gebracht. Zo worden de voorzichtige alpenmarmot en de onbesuisde eekhoorn tegenover elkaar geplaatst, lezen we over volgzame schapen en dwarse geiten en ontdekken we hoe het geduld van de spin de rusteloze vlieg in zijn web doet vliegen. En de lijst is lekker lang: we ontmoeten snelle en trage dieren, lenige en logge, deftige en alledaagse, krachtige en kwetsbare, opvallende en onopvallende, ? De brug naar onze eigen aard is makkelijk gelegd. Zo krijgen kinderen vat op de rijkdom van onze taal en de keur aan eigenschappen die ze in zichzelf en in anderen kunnen herkennen. En toch genoten we nog het meest van al van het het sprankelende taalgebruik en de tekeningen die de dieren laat schitteren in hun rol. Het speelse, dravende en ritmische van Westera?s taal loopt wondermooi samen met de kleurrijke illustraties van Mies van Hout die de verbeelding van de verschillende eigenschappen enkel nog versterken. Hier kunnen we enkel blij van worden! En we zijn ervan overtuigd dat jonge lezertjes, hun ouders en hun leraren van allerhande aard er ook hun gading in zullen vinden.

Diagenesis of carbonates and clastic sediments encompasses the biochemical, mechanical, and chemical changes that occur in sediments subsequent to deposition and prior to low-grade metamorphism. These parameters which, to a large extent, control diagenesis in carbonates and clastic sediments include primary composition of the sediments, depositional facies, pore water chemistry, burial–thermal and tectonic evolution of the basin, and paleo-climatic conditions. Diagenetic processes involve widespread chemical, mineralogical, and isotopic modifications affected by the original mineralogy of carbonate and clastic sediments. These diagenetic alterations will impose a major control on porosity and permeability and hence on hydrocarbon reservoirs, water aquifers, and the presence of other important economic minerals. In this Special Issue, we have submissions focusing on understanding the interplay between the mineralogical and chemical changes in carbonates and clastic sediments and the diagenetic processes, fluid flow, tectonics, and mineral reactions at variable scales and environments from a verity of sedimentary basins. Quantitative analyses of diagenetic reactions in these sediments using a variety of techniques are essential for understanding the pathways of these reactions in different diagenetic environments.
