Magnesium and magnesium-derived alloys are critical to a diverse set of industries, due to their particular physicochemical properties, including biocompatibility, low density, mechanical dampening, and hydrogen-storage capacity. Moreover, the magnesium compounds are themselves vital in agricultural, pharmaceutical, construction and broad industrial applications. Leaching is a critical step in the recovery of magnesium from magnesium-bearing ore, and the most common leaching agents are organic and inorganic acids, as well and ammonium salts, the efficacy of which depends on the mineral feed. Organic acids are used with minerals having fast leaching kinetics; these acids have less dissolving power but are more selective and are less destructive to the equipment. In contrast, inorganic acids have more dissolving power and are easier to source. However, the inorganic acids are less selective and cause more damage to equipment, as they complicate pH control. The objective of this work has been to review studies on the kinetics of magnesium mineral extraction, and the effects of critical parameters depending on the feed mineral and the reagents. Several works are presented on the leaching kinetics of natural and calcined dolomite and magnesite, and hydrated magnesium salts, as well as ferromagnesian silicates and serpentinite, which are important sources of magnesium. It has been shown that the most influential parameters in dissolving magnesium are the temperature and the reagent concentration, which have a direct effect on magnesium extraction rates. However, there is a point at which increases in these parameters result in more impurities and/or have insignificant effects on magnesium dissolution. Particle size has an inverse relationship to magnesium extraction since the area of contact with the leaching surface is greater with smaller particles. The effect of the agitation speed is insignificant with magnesite feeds, given that the process is controlled largely by surface chemical reactions, while the leaching kinetics of serpentinite is controlled by diffusion through the product layer.

镁和镁衍生的合金由于其特殊的物理化学特性，包括生物相容性，低密度，机械阻尼和储氢能力，对多种工业至关重要。此外，镁化合物本身在农业，制药，建筑和广泛的工业应用中至关重要。浸出是从含镁矿石中回收镁的关键步骤，最常见的浸出剂是有机酸和无机酸以及铵盐，其有效性取决于矿物质。有机酸与具有快速浸出动力学的矿物一起使用；这些酸的溶解力较小，但选择性更高，对设备的破坏性较小。相反，无机酸具有更高的溶解能力并且更容易获得。但是，无机酸的选择性较差，对设备的损害更大，因为它们使pH控制变得复杂。这项工作的目的是回顾镁矿物质提取动力学的研究，以及取决于饲料矿物质和试剂的关键参数的影响。关于天然和煅烧的白云石和菱镁矿以及水合镁盐以及铁镁镁硅酸盐和蛇纹石的浸出动力学的几项工作已经提出，它们是镁的重要来源。已经表明，溶解镁最有影响力的参数是温度和试剂浓度，它们直接影响镁的提取速率。然而，这些参数的增加会导致更多的杂质和/或对镁溶解的影响不明显。粒径与镁的提取成反比关系，因为较小的颗粒与浸出表面的接触面积更大。考虑到该过程很大程度上受表面化学反应控制，而蛇纹石的浸出动力学受产物层中的扩散控制，因此搅拌速度对菱镁矿进料的影响并不明显。
