The recovery of zinc from its deposits is a multifaceted process involving several stages. Initially, the metalliferous ore undergoes pulverization to reduce it into smaller pieces. This milled material is then subjected to a concentration process, typically involving flotation, to increase the zinc content. Following refined ore production, smelting melts the concentrate into crude zinc metal. This raw zinc undergoes further purification steps such as electrolysis or distillation to produce high-purity zinc suitable for various applications.
