Reactive Transport Modeling Applied to Ni Laterite Ore Deposits in New Caledonia: Role of Hydrodynamic Factors and Geological Structures in Ni Mineralization

摘要

Abstract >This study is devoted to understanding the impact of topography and hydrodynamics on the formation of high‐grade supergene nickel deposits. The investigation proposes a new conceptual mineralization model that describes the formation of various exceptionally Ni‐enriched hot spots observed in lateritic profiles. Numerical analysis of the effects of local hydrodynamics on deposits formation is performed by means of PHREEQC geochemical simulator and COMSOL Multiphysics software. These are coupled through an iCP Java interface that allows to code their level of interaction and facilitates the exchange of parameters. The model developed extends the currently existing geochemical formulation of nickeliferous laterite formation from peridotite carried out in 1‐D and is additionally capable of simulating mass solute transport and geochemical processes within complex fractured‐porous systems. The simulations improve our understanding of metal enrichment in saprolite and bedrock zones. It was shown that, although the initial development of nickel lateritic ores takes a few million years, they are prone to relatively quick leaching and subsequent redistribution of Ni when the topography changes in response to tectonic processes. The latter leads to the formation of rich nickel deposits at the bottom of the slope, mostly due to leaching of the saprolite material. In addition to the role of changes in topography, the critical impact of fractures and fracture networks on metal mobility and distribution was identified. The model developed provides significant insight into the distribution of mineral resources, in particular Ni deposits, and can be of great help for future mineral prospecting in industry. </abstract>

本研究致力于了解地形和流体动力学对高级叠加镍沉积物的影响。该研究提出了一种新的概念矿化模型，该模型描述了在外层谱中观察到的各种富集的热点的形成。通过Phreeqc地球化学模拟器和COMSOL Multiphysics软件进行局部流体动力学对沉积物形成的数值分析。这些通过ICP Java接口耦合，允许编码其交互级别并促进参数交换。该模型延伸了在1-D中进行的恒星岩石中的现有现有的地球化学制剂，并且另外能够在复杂的裂缝多孔系统中模拟质量溶质转运和地球化学方法。该模拟改善了我们对藏宝石和基岩区域的金属富集的理解。据表明，虽然镍外矿石的初始开发需要几百万年，但是当地形变化响应构造过程时，它们易于伴随相对快速的浸出和随后的Ni再分配。后者导致在斜坡底部形成富镍沉积物，主要是由于浆砂材料的浸出。除了地形变化的作用外，还确定了骨折和裂缝网络对金属移动性和分布的临界影响。该模型开发了对矿产资源的分布，特别是Ni矿床的分布提供了重要的洞察力，并且对工业中未来的矿物勘探可能有很大的帮助。</
