Galena not a rock its a Economic mineral of lead. Formula of Galena is PbS. Galena and Sphalerite(ZnS) Found togather at Hydrothemal deposits.
No, Galena does not always split into small cubes. While Galena commonly forms cubic crystals due to its crystal structure, it can also occur in other forms and crystal habits depending on its growth conditions.
No, galena is a naturally occurring mineral that is the primary ore of lead. It forms in hydrothermal and sedimentary processes in the Earth's crust.
Galena is an ore of lead that is commonly found in hydrothermal veins associated with igneous and metamorphic rocks. It forms through the deposition of lead minerals in these geological environments over time.

Graphite is a soft, black mineral that leaves a streak on paper and is used in pencils. Galena is a lead-gray mineral that is heavy and often forms cube-shaped crystals. One way to distinguish them is by conducting a streak test - graphite will leave a black streak, while galena will leave a gray streak.
Galena is a mineral.
Galena's cleavage is cubic.

First: Roast the Galena in a blast furnace for 30 minutes. Second: Add Carbon to the blast furnace to remove impurities. Third: Tag off your lead from the bottom of the blast furnace.
Galena's fracture is subconchoidal, and its cleavage is cubic. See http://www.minerals.net/mineral/sulfides/galena/galena.htm for a complete chart about galena's properties.
