Extracting Lead Materials from Ore nuclead
Extracting Lead Materials from Ore. Lead is a dense, soft, low-melting metal. Lead is the densest common metal except for gold, and this quality makes it effective in sound barriers and as a shield against X-rays.Lead resists corrosion by water, so it makes a long-lasting roofing material.. Only about half of the lead materials used today are produced from mining, the rest is obtained from

But if we use zinc to extract iron, then the zinc is gone! Remember we need to extract zinc too from its ore to extract iron. This does not make sense, it is like making cakes with cupcakes, we need to make the cupcakes first in order to make the cake ( ͡° ͜ʖ ͡°) But carbon, on the other hand, is a better alternative. Carbon is more reactive than iron, plus also it is cheaper and
Sphalerite, which is a form of zinc sulfide, is the most heavily mined zinc-containing ore because its concentrate contains 60–62% zinc.
