  • Biomining

    History of biomining. The very first recognized biomining system was published in 1951 when Kenneth Temple PhD discovered that Acidithiobacillus ferrooxidans thrives in iron, copper and magnesium rich environments. In Temple's experiment, A. ferrooxidans was inoculated into media containing between 2,000 and 26,000 ppm ferrous iron. He discovered that the bacteria grew faster and were more

  • Mining Underground mining Britannica

    Mining Underground mining When any ore body lies a considerable distance below the surface, the amount of waste that has to be removed in order to uncover the ore through surface mining becomes prohibitive, and underground techniques must be considered. Counting against underground mining are the costs, which, for each ton of material mined, are much higher underground than on the surface.

  • Industrial Revolution

    The Industrial Revolution was the transition to new manufacturing processes in Europe and the US, in the period from about 1760 to sometime between 1820 and 1840. This transition included going from hand production methods to machines, new chemical manufacturing and iron production processes, the increasing use of steam power, the development of machine tools and the rise of the factory system.

    In this paper, a hybrid energy economy that packages hydrogen chemically on carbon atoms from various sources including recycled CO 2 is introduced and discussed. For this new hybrid energy economy to become a sustainable reality, the ability to recycle CO 2 and attach hydrogen to create a usable energy product, such as dimethyl ether, is needed.
