Global move away from oil could lead to conflict and migration, experts say

Researchers urge governments to help worst afflicted countries, such as Nigeria and Algeria, which rely on oil revenues for public services

Conflict, migration and economic upheaval will accompany the global move away from oil, unless governments act urgently to help the worst afflicted countries to cope, research has found.

Nigeria, Iran, Angola and Algeria are among the countries that will be severely affected, as they rely strongly on oil revenues for their government and provision of public services, but have little diversification and too little capital to cushion the blow.

How Particle Size Affects Rare Earth Ore Behavior

20 June 2026 at 20:18

In a groundbreaking study published in Scientific Reports, a team of researchers led by Liu, D., Li, X., and Zhang, Z. has unveiled pivotal insights into the intricate mechanisms dictating how particle size influences the migration and deposition behaviors of weathered crust elution-deposited rare earth ores. This investigation probes deeply into the physicochemical principles and dynamic environmental interactions responsible for the distribution patterns of these valuable mineral resources, providing an unprecedented lens on their geochemical mobility.

The research tackles the challenge of understanding the migration pathways of rare earth elements (REEs) within the weathered crust, a layer significantly dictating ore generation. Central to their inquiry is the particle size of these ore constituents, which affects not only sediment transport dynamics but also the ore’s eventual deposition patterns through complex physicochemical interactions with surrounding media. The work bridges gaps between mineralogy, sedimentology, and geochemistry, offering a holistic view important for both scientific and industrial applications.

Their methodology encompassed a series of meticulously designed experiments and computational models to simulate natural conditions accurately. By varying particle sizes in controlled settings, the research team could monitor kinetic behaviors, adhesive interactions, and sedimentation rates of particles subjected to elution and migration processes. This allowed them to unravel size-dependent mechanisms underlying the spatial distribution and aggregation tendencies of REE particles within lateritic profiles.

In particular, the findings underscore the critical role of smaller particle fractions, which exhibited enhanced mobility due to lower gravitational settling but showed a propensity to adsorb onto mineral surfaces, thus influencing local concentration hotspots. Conversely, larger particles demonstrated reduced migration, primarily influenced by mechanical transport limits and gravitational forces, leading to more stable deposition zones. These differential behaviors directly affect the ore-forming processes and the quality of recoverable deposits.

Chemically, weathered crust environments present dynamic pH and redox conditions, which modulate particle surface charge, coagulation tendencies, and dissolution rates. The research elaborates how particle size accentuates these processes, with fine particles showing increased surface area promoting more extensive ion exchange and adsorption phenomena. Such micro-scale interactions substantially dictate macro-scale deposition patterns, impacting exploration strategies targeting rare earth mineralizations.

Moreover, the research extends its implications to understanding the environmental fate of rare earth elements beyond mining contexts. Rare earth particles, when mobilized through weathering, can traverse soil and water systems, posing ecological and human health risks. The particle size-dependent migration insights unveiled serve as crucial input for predictive environmental risk assessments and remediation planning around mining sites.

One of the most compelling aspects of the study is its integration of field data with laboratory results, ensuring real-world relevance. Samples collected across multiple deposit sites demonstrated consistent size-dependent migration tendencies, validating laboratory conclusions and revealing nuanced local variations driven by topographical and hydrological factors. Such data synthesis enhances the predictive power of their proposed migration and deposition models.

Their study also contributes to refining current geochemical theories related to elution-deposited ores, challenging prior assumptions that often overlooked particle size as a key variable. By pinpointing size-specific migration thresholds, the researchers clarify ore genesis mechanisms in weathered crusts, a region crucial for the global rare earth supply chains. This knowledge can revolutionize resource estimation practices, allowing for improved accuracy in reserve quantification.

Technologically, the researchers leveraged state-of-the-art microscopy and spectroscopic techniques to characterize particle morphologies, mineral compositions, and surface chemistry details. These sophisticated analytical methods provided high-resolution data necessary to comprehend how particle physical attributes interact with chemical environments, culminating in comprehensive migration and deposition profiles. This multidimensional approach epitomizes modern Earth sciences research.

The implications for mining engineering and metallurgy are profound. Understanding particle size effects on ore distribution allows for optimized beneficiation processes, enhancing the efficiency and economic viability of rare earth extraction. Tailored grinding, sorting, and sedimentation techniques can be developed based on specific ore particle sizes, reducing waste and environmental footprints. This research lays the foundation for such industry advances.

Further, the research opens avenues for innovative environmental management practices. By predicting rare earth particle transport pathways, stakeholders can implement targeted monitoring and control strategies to minimize ecological disturbances. This is particularly relevant in the context of expanding rare earth mining activities fueled by the global demand for clean energy technologies, where sustainable practices are paramount.

The interdisciplinary essence of the research, combining geology, chemistry, physics, and engineering, sets a benchmark for future studies addressing complex natural and anthropogenic processes influencing critical mineral resources. The clarity gained about particle size’s role in migration and deposition elucidates broader Earth system processes, benefiting multiple scientific domains and policy frameworks concerning resource stewardship.

In conclusion, Liu and colleagues’ study represents a significant advancement in our understanding of the fundamental processes underlying rare earth ore formation within weathered crust environments. Their comprehensive focus on particle size effects offers vital scientific and practical insights, opening new research horizons and contributing to the sustainable development of an indispensable resource underpinning modern technologies.
