Description

Jarosite CAS NO 12207-14-6 is a hydrated potassium iron sulfate hydroxide mineral with significant industrial relevance. This compound is valued for its role in environmental remediation and metallurgical processing, particularly in the treatment of acid mine drainage and as a precursor in pigment manufacturing. It serves as a critical material for industries including mining, wastewater treatment, and the production of inorganic colorants and construction materials.

Application

• Environmental remediation for the sequestration of heavy metals in acid mine drainage and industrial wastewater.
• Raw material in the production of inorganic pigments, such as yellow ochre and Mars yellow.
• Precursor in metallurgical processes for iron recovery and as a feedstock for sulfate-based chemicals.
• Component in soil amendment and stabilization applications to manage pH and metal mobility.
• Use in construction materials as a mineral additive or filler.
• Research and development of battery cathode materials and other advanced energy storage technologies.
• Catalyst or catalyst support in specific chemical synthesis processes.
• Analytical chemistry as a reference standard for mineralogical and geochemical studies.
