Due to the increasing demand for zinc ingots in Iran and the decline of high-grade mineral resources, active factories in this field are compelled to use low-grade ores within the country or import ores from neighboring countries. Low-grade zinc ores generally contain more impurities compared to high-grade ores. If impurities such as iron, copper, nickel, cobalt, cadmium, chlorine, fluorine, lead, and others are not properly controlled during the process, the production of zinc ingots can face significant challenges or even become economically unviable. Producing high-purity zinc ingots with lead content of less than 20 grams per ton (ppm) requires proper design and optimization of the traditional processes currently used in Iran. Optimized design and engineering of zinc ingot production equipment can greatly impact overall process efficiency. Moreover, minimizing the use of chemicals in neutralization, hot and cold purification, and electrowinning processes can significantly increase the net profit of the factory.

The Faramine Asia Industrial and Mining Group, utilizing its experts and collaborating with senior industry managers, is capable of designing, constructing, and optimizing zinc ingot production plants. This Group can produce and supply high-quality, high-purity products to the market using both high-grade and low-grade ores.
