The extraction of zinc from its ore is a multifaceted process involving several stages. Initially, the zinciferous ore undergoes pulverization to break down it into smaller particles. This milled material is then subjected to a separation process, typically involving flotation, to increase the zinc content. Following refined ore production, smelting transforms the concentrate into crude zinc metal. This raw zinc undergoes further treatment steps such as electrolysis or distillation to produce commercial-grade zinc suitable for various applications.
