The Spray Dryer Unit at the Ahangaran Mining & Industrial Complex is one of Sormak Mines Company's specialized processing facilities dedicated to the production of value-added mineral products. The unit has been designed to manufacture Zinc Sulfate Monohydrate (ZnSO₄·H₂O) and plays an important role in completing the Company's zinc processing value chain.

Spray drying is one of the most advanced industrial drying technologies, in which a zinc sulfate solution is atomized into fine droplets and brought into contact with a stream of hot air. The rapid evaporation of moisture converts the solution into a free-flowing powder with uniform particle size distribution. This process ensures high product quality while producing a material with controlled moisture content, excellent flowability, and high chemical purity.

Production Process

In this unit, the zinc sulfate solution produced through hydrometallurgical processing is first adjusted to the required concentration and quality before being fed into the spray dryer. The solution is atomized into fine droplets by a high-performance atomizer and exposed to a controlled stream of hot air, where moisture is rapidly removed to produce Zinc Sulfate Monohydrate powder.

The dried product is subsequently recovered through powder collection systems, subjected to quality control, and packaged for distribution to domestic and international markets.
