In nature, the tin ore are existing in sand or alluvial raw material, this kind tin ore called sand tin or alluvial tin, those raw material may be with stone, sand, gravel, soil, sticky clay, some times with other magnetic iron, tungsten, ilmenite, hematite, monazite, zircon sand and other minerals.. …
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.

Lead-zinc ore is a polymetallic mineral rich in elemental lead and zinc, mainly in lead-zinc sulfide and lead-zinc oxide ore. Among them, lead-zinc sulfide ore is an easy-to-select ore; lead-zinc oxide ore is a difficult-to-select ore. Due to the increasing global demand for lead-zinc mineral resources, both lead-zinc ores are valuable for mining.
