Although there are many kinds of copper smelting processes in China, they are all famous for their advanced nature and high efficiency. Among them, because of its high desulfurization rate and energy saving, flash smelting has become the most popular smelting process in China, and its production capacity accounts for about 3%-4% of the roughing capacity of domestic copper smelters. Copper smelting concept stocks refer to the stocks of listed companies engaged in copper smelting. What are the copper smelting concept stocks?
