Description

Zinc Ores, Concs., Preleached CAS NO 69011-86-5 refers to a processed intermediate material derived from zinc-bearing ores, specifically concentrated and treated to remove certain soluble impurities prior to final metal extraction. This product is critical for ensuring efficient and cost-effective downstream smelting and refining operations by providing a more consistent and higher-grade feed material. It is primarily required by non-ferrous metal producers, zinc smelters, and chemical manufacturers involved in the production of zinc metal, zinc compounds, and alloys.

Application

• Primary feed material for zinc smelting and electrolytic refining processes.
• Intermediate raw material in the production of zinc sulfate, zinc oxide, and other zinc chemicals.
• Precursor for the manufacturing of galvanizing alloys and die-casting alloys.
• Used in hydrometallurgical processing circuits for zinc recovery.
• Source material for cathode active materials in certain battery chemistries.
• Feedstock for agricultural micronutrient supplements after further processing.
