The Lehong deposit exhibits two types of mineralization: Pb-Zn and Cu. Spatially, the copper ore bodies are found in deeper strata than the lead–zinc ore bodies, with both hosted in dolostone. In the samples we collected, galena is observed to be replaced by copper minerals, suggesting that Cu mineralization occurred after Zn-Pb mineralization.

About Pb-Cu. Lead and zinc are extremely close in nature, especially in primary deposits, and often coexist. Most of the lead-zinc minerals are sulfides and sulfates, and galena and sphalerite are the primary Pb-Zn ores. Non-sulfide: It is formed due to hypogene and supergene weathering. Mostly oxide ores like zincite, and cerussite may fall under this category.

The final stage in iron ore processing is ironmaking, where the iron ore is transformed into molten iron through a process called reduction. The most common method of ironmaking is the blast furnace route. In a blast furnace, iron ore, coke (carbon), and fluxes (limestone or dolomite) are loaded into the furnace from the top.
