Solubilization
Minerals after crushing will go for leaching which would be in contact with sulfuric acid to extract zinc in shape of Zinc sulfate. Zinc sulfate solution will go for cold/Hot purification which exported makeup gets ready for electrolysis. Electrolysis process is contain of 2 pulp vessels, 5 leaching vessels with total volume of 175 cubic meters and official volume of 154 cubic meters. By help of 4 filter press devices, Tal Zinc Smelter Co. is able to produce 280 cubic meters Zinc sulfate solution in this process.
Purification
Output solution will go into the purification vessels in order to remove impurities like Cobalt, Nickel, and Cadmium from Zinc sulfate solution. Pure solution will be transferred into the electrolysis process.
Electrowining
In this process, pure Zinc sulfate solution with applying electricity will turn into the sheets on cathodes surface. This section consists of 60 cells which there would be cathodes with substance of aluminums and Anode with substance of lead. Transformer and rectifier are providing required electricity for this process. Ion zinc with DC flow will be absorbed on cathodes surface, each 24 hours zinc sheets will be peeled and gets ready for melting.
Casting
In this process, extracted zinc sheets from electrowining will be transferred into the furnace and output molten will be placed into cast-iron molds. Produced ingots would be packaged in 1 ton bandils.
Leaching Department
In this department 4 vessels of leach, 3 vessels of hydroxide, and 5 devices of filter-press have capability of washing 180 tons of soil which causes significant increase of efficiency and optimized utilization of mineral resources.
Technical Department
In this department Mechanic, civil and power engineers have duty of Repair and Maintenance, fix damage and Prevention of production line stops. Also planning and consultation of performing projects.
Laboratory and QC
This department has equipped with VARIAN device in order to do analysis. All input materials, production process and final products will be analyzed and certified by experts of this department sequentially.
