    Biomining: metal recovery from ores with microorganisms

    Biomining is an increasingly applied biotechnological procedure for processing of ores in the mining industry (biohydrometallurgy). Nowadays the production of copper from low-grade ores is the most important industrial application and a significant part of world copper production already originates from heap or dump/stockpile bioleaching.

    What Is Copper Smelting? (with pictures)

    Kirsten C. Tynan Copper wire. Copper smelting is the process of separating copper metal from the rock in which it is naturally embedded by melting it. This is accomplished through a series of several processing steps. The term copper smelting may refer to this melting step in particular or it may refer somewhat less formally to the entire process overall.

    Innovations: Introduction to Copper: Mining & Extraction

    Copper minerals and ores are found in both igneous and sedimentary rocks. Mining of copper ores is carried out using one of two methods. Underground mining is achieved by sinking shafts to the appropriate levels and then driving horizontal tunnels, called adits, to reach the ore. Underground mining is, however, relatively expensive and is ...

    Sep 08, 2015 The Quincy Mining Company was formed in 1848. By 1900, high on the hill above Houghton-Hancock, it had assembled all the infrastructure needed to mine, process, ship and smelt the ore. It was an underground mine 9260 feet at its deepest, and eventually was unable to compete with open pit strip mining out west.

    Agitated Tank Bioleaching

    Bioleaching processes in mechanically-agitated tanks are usually applied for the treatment of flotation concentrates derived from sulfidic ores. The valuable components in these concentrates can be gold, uranium and a variety of base metals such as copper, nickel, zinc and cobalt.
