The surface dissolution reactions of silicate minerals are a critical component in controlling geochemical element cycling. This paper systematically reviews the dissolution behavior characteristics of typical silicate minerals (e.g., feldspar, kaolinite, montmorillonite, and quartz) under varying solution conditions, and summarizes the synergistic regulatory effects of mineral crystal structures (phyllosilicate, tectosilicate), environmental conditions (pH, temperature, pressure), and acid solution types (organic/inorganic acids) on their surface dissolution processes. The study focuses on the reaction features and mechanisms of silicate mineral surface dissolution in diverse environments, with further discussion on the application of acid treatment in developing environmental mineral materials. By synthesizing global literature, the following insights are derived: 1) pH exerts broadly similar controls on silicate mineral dissolution rates, yet exhibits subtle variations across mineral types; 2) Acid solution types govern dissolution through distinct reaction mechanisms; 3) Acid etching modifies mineral structures and surface properties, thereby influencing their surface reactivity. This review provides theoretical references for modeling surface dissolution behavior of silicate minerals in multicomponent systems and their coupling mechanisms with heavy metals. %K 硅酸盐矿物, %K 表面溶解, %K 地球化学循环
