Galena is lead sulfide with a hardness of 2.5 on the Moh's scale - actually quite soft- but it is VERY heavy with a specific gravity of 7.4 to 7.6. To put that in perspective, it weighs about 700 pounds per cubic foot! Although lead is by far the most reclaimed industrial metal in the world, demand for it continues to outstrip the supply.

Galena, a mineral of both historical and geological significance, is a. : The name is derived from the Latin galena, a name originally given to lead ore. . Isometric; hexoctahedral.

The present-day City of Galena is named after the Latin word for lead, galena. Galena's first boatload of lead ore went down the Mississippi River in 1816. Three years later, a trading post was built in Galena that led to the first steamboat arrival in 1824. By 1845 Galena was producing nearly 27,000 tons of lead ore and Jo Daviess County was ...

Galena, Cubic, Approximately 2.5″-3″ Length, 1 1/4lbs., Single Piece. Galena is a mineral composed primarily of lead (II) sulfide (PbS).

Precision: Galena (lead ore) weighs 7.6 gram per cubic centimeter or 7 600 kilogram per cubic meter, i.e. density of galena (lead ore) is equal to 7 600 kg/m³. In Imperial or US customary measurement system, the density is equal to 474.45 pound per cubic foot [lb/ft³], or 4.39 ounce per cubic inch [oz/inch³] .

Galena is the ore from which elemental lead is extracted. In the first step of the extraction process, galena is heated in air to form lead(II) oxide. 2PbS(s) + 3O2(g) → 2PbO(s) + 2SO2(g) ΔH = -827.4 kJ What mass of galena is converted to lead oxide if 975 kJ of heat are liberated? A. 203 gB. 282 gC. 406 gD. 478 gE. 564 g

Roasting galena [lead(II) sulfide] is an early step in the industrial isolation of lead. How many liters of sulfur dioxide, measured at STP, are produced by the reaction of 7.16 kg of galena with 166 L of oxygen gas at 220 Celsius and 2.00 atm? Lead(II) oxide also forms.

Galena is lead sulfide with a hardness of 2.5 on the Moh's scale - actually quite soft- but it is VERY heavy with a specific gravity of 7.4 to 7.6. To put that in perspective, it weighs …

The 60% owned Galena Complex is located in Idaho's prolific Silver Valley, a district famous for producing silver, lead, zinc and copper from such well-known operations as the Bunker Hill, Sunshine and Lucky Friday mines. …
