  • What is Involved in Molybdenum Mining? (with pictures)

    The first step in strip mining for molybdenum is using a dragline excavator. Thousands of tons in weight, the excavator looks like a giant moving crane with a bucket attached to the end of its boom. With the use of ropes and pulleys, the bucket is dragged along the ground picking up plants, topsoil, and eventually the bedrock. Once all ore has been retrieved, the excavator moves to a new location and repeats the

    Molybdenum mining and processing techniques have been improved continuously since the first mine was started at Climax near Leadville, Colorado in 1916. Today, the principal moly mines, both primary and by-product, are found along the Great Continental Divide of the Americas, in China and in the CIS. Many of these mines are amongst the most productive in the world, with the largest capable of moving

  • Molybdenum Mining IMOA

    Mining. Molybdenum is contained in various minerals, but only molybdenite (MoS 2) is suitable for the industrial production of marketable molybdenum products. Molybdenite can occur as the sole mineralization in an ore body, but is often associated with the sulphide minerals of other metals, notably copper. The Mo content of viable ore bodies ranges

  • Molybdenum Minerals Education Coalition

    Molybdenum was discovered by Carl Wilhelm Scheele in 1778, and was isolated and named by Peter Jacob Hjelm in 1781. The most important ore source of molybdenum is the mineral molybdenite; a minor amount is recovered from the mineral wulfenite. Molybdenum commonly is recovered as a by-product or co-product from copper mining. The U.S. produces significant quantities of molybdenite. The major
