Understanding ore texture is essential for optimising comminution and mineral liberation, yet no standardised framework exists for defining and quantifying textural attributes. This review explores the complex relationship between ore texture, breakage mechanisms, and mineral liberation, emphasising the importance of textural parameters such as grain size, mineral intergrowths, and mechanical properties in determining comminution behaviour. The review is structured into key themes: (i) characterisation techniques for ore texture, spanning optical, electron beam, X-ray, and laser-based methods; (ii) conventional and proxy comminution tests for assessing ore hardness and breakage response; (iii) modelling approaches to relate ore texture to mineral liberation, including texture-based and kinetic-based liberation models; and (iv) innovative pre-treatment methods such as microwave heating, high-voltage pulse disintegration, and ultrasonication, which aim to promote non-random breakage and improve mineral liberation. The literature is analysed through a comparative assessment of these methods, evaluating their applicability, limitations, and integration potential in modern mineral processing.

探索矿石质地在碎磨中的作用以及识别和促进非随机破碎的方法

了解矿石质地对于优化碎磨和矿物释放至关重要，但目前尚无定义和量化纹理属性的标准化框架。这篇综述探讨了矿石质地、破碎机制和矿物游离之间的复杂关系，强调了纹理参数（如粒度、矿物共生和机械性能）在决定碎磨行为中的重要性。本综述分为关键主题：（i） 矿石纹理的表征技术，涵盖光学、电子束、X 射线和基于激光的方法;（ii） 用于评估矿石硬度和破碎响应的常规和代理碎磨测试;（iii） 将矿石纹理与矿物释放联系起来的建模方法，包括基于纹理和基于动力学的释放模型;（iv） 创新的预处理方法，如微波加热、高压脉冲崩解和超声波处理，旨在促进非随机断裂并改善矿物释放。通过对这些方法的比较评估来分析文献，评估它们在现代矿物加工中的适用性、局限性和整合潜力。
