Porphyry copper deposit - Wikipedia

The first mining of low-grade copper porphyry deposits from large open pits coincided roughly with the introduction of steam shovels, the construction of railroads, and a surge in market demand near the start of the 20th century. Some mines exploit porphyry deposits that contain sufficient gold or molybdenum, but little or no copper.

Molybdenum Statistics and Information

Molybdenum (Mo) is a refractory metallic element used principally as an alloying agent in steel, cast iron, and superalloys to enhance hardenability, strength, toughness, and wear and corrosion resistance. To achieve desired metallurgical properties, molybdenum, primarily in the form of molybdic oxide or ferromolybdenum, is frequently used in combination with or added to

Molybdenum - Wikipedia

Though molybdenum is found in such minerals as wulfenite (PbMoO 4) and powellite (CaMoO 4), the main commercial source is molybdenite (MoS 2). Molybdenum is mined as a principal ore and is also recovered as a byproduct of copper and tungsten mining.
