Easily recognized by it good cleavage, high specific gravity, softness, and lead-gray streak, this mineral is the primary ore mineral of lead. It is a very common sulfide that has been worked for its lead content as early as 3000 BC. The name is derived from the Latin galena, a name originally given to lead ore. Lead can be prepared from galena [lead(II) sulfide] by first roasting the galena in oxygen gas to form lead(II) oxide and sulfur dioxide. Heating the metal oxide with more galena forms the molten metal and more sulfur dioxide. How many metric tons of sulfur dioxide form for every metric ton of lead obtained? (_) 1.3 10 4 metric tons SO 2 Specific gravity (unitless) is the ratio of the mass of a mineral to the mass of an equal volume of water at 1 atm, and because mass and weight are proportional, we normally determine specific gravity by comparing weights.
