  1. A major and primary Lead mineral is galena (PbS) which comprises of 86.6% of lead. …
  2. 1) The galena is roasted (reacts with O2) in order to remove the sulfur component of the metal sulfide. …
  3. 2) The newly formed Lead (II) Oxide subsequently reacts with coke to attain refined Lead.

Is galena soluble?

Sphalerite and galena solubilities have been experimentally determined under H2S-saturated conditions over the 3–5 molal (=m) NaCl range and for temperatures up to 95°C. Both ZnS and PbS are about 5 times more soluble in 5 m than in 3 m NaCl brines.

How do you extract metal from galena?

Galena is usually associated with other sulfide ores such as sphalerite. The lead concentrate was able to be extracted and purified into its metal through a leaching process using a selective solvent of fluosilicic acid (H2SiF6).
