A mechanochemical leaching process by mechanical ball milling in the aqueous solution containing Pb chloride or Pb nitrate was proposed for the separation of smithsonite and cerussite. XRD analyses revealed the formation of Pb₂(CO₃)Cl₂ and PbCO₃, respectively, in the residues by the mechanochemical reaction of smithsonite with the Pb chloride and Pb nitrate solution. These results show that smithsonite could be selectively dissolved in the aqueous solutions containing Pb chloride and Pb nitrate with obtained smithsonite dissolution efficiency of 92.7% and 99.6%, respectively. This study provides a novel and simple hydrometallurgical process for the separation of smithsonite and cerussite, exhibiting a high-efficiency feature over the traditional flotation separation process and acidic leaching process.

提出了通过机械球磨在含氯化铅或硝酸铅的水溶液中进行机械化学浸出的方法，以分离铁矿和陶粒。XRD分析表明Pb ₂（CO ₃）Cl ₂和PbCO _3的形成铁矿与氯化铅和硝酸铅溶液的机械化学反应分别残留在残留物中。这些结果表明，新铁矿可以选择性地溶解在含氯化铅和硝酸铅的水溶液中，得到的新铁矿的溶解效率分别为92.7％和99.6％。这项研究提供了一种新的，简单的湿法冶金工艺，用于分离铁矿石和陶粒，与传统的浮选和酸性浸出相比，具有高效的特点。
