The iron ore shown to the right was excavated from Skógar, a Viking-age iron-making site in Iceland. The larger piece is about 2cm (less than 1in) in the long dimension. Sometime about 1000 years ago, someone gathered this iron ore, processed it, transported it to the iron smelting site, but for unknown reasons, never used it in a smelt. Once the dry nodules or ore was in …

Traditional drilling methods into deep ocean basins depend on thick layers of sediment to provide lateral support for the flexible drill string to penetrate the surface. Because the ocean floor at the mid-ocean ridge does not have this protective layer, drilling into the newly formed crust called for a different technique. After an intensive year of research and development, this …
· Examples of metals are Manganese ore, Iron ore and Bauxite ore are few examples of metals. This process is called drilling. Those minerals which can be found easily near the surface of earth can be simply dug out by the process called as quarrying. Distribution of Minerals. Minerals can be found in different varieties of rocks. They are found in different types …
compass was used in Sweden in the mid-1600s to find iron ore deposits. The lateral extent of the Comstock ore body was mapped using self-potential methods in the 1880s. A very crude type of seismic survey measured the energy resulting from blasting operations in Ireland in the late 1800s. The idea that energy travels through a material with a certain velocity came from this …
· Ore is brought to the surface through tunnels and shafts for processing, and waste rock for disposal. Sub-surface mining can be classified according to the type of shafts used, the method of extraction or the technique used to reach the deposit. Drift mining uses horizontal access tunnels, diagonally sloping access shafts are used by slope mining, and shaft mining …
