The zinc ingot prices observed a downward wavering trend during the first quarter of 2024. The primary reason behind these slumping trends was a consistent rise in the output quantities. Zinc output is seeing a rise globally, and Chinese zinc output is expected to rise by about 500 KMT by the next year.

In the pyrometallurgical process, ore concentrate containing lead, zinc, or both is fed, in some cases after sintering, into a primary smelter. Lead concentrations can be 50-70%, and the sulfur content of sulfidic ores is in the range of 15-20%. Zinc concentration is in the range of 40-60%, with sulfur content in sulfidic ores in the range of ...

Later, in 1617, the German Georg Engelhardt von Löhneyss (1552–1622) used the term "zinc" for describing the production process of Rammelsberg—Germany ore (Sinclair 2005; Habashi 2018). In 1805, it was discovered in Sheffield, England, that sheet metal could be produced by annealing Zn at 100–105 °C.
