• Underground mining (hard rock) Wikipedia

    Underground hard rock mining refers to various underground mining techniques used to excavate hard minerals, usually those containing metals such as ore containing gold, silver, iron, copper, zinc, nickel, tin and lead, but also involves using the same techniques for excavating ores of gems such as diamonds or rubies. Soft rock mining refers to excavation of softer minerals such as salt, coal

  • Are You Mining Minerals for Cement, or for Concrete?

    Cement is the grey powdery stuff that when mixed with sand, rock, gravel and water forms concrete. The concrete is the final product used in buildings, roads, infrastructure, etc. You can think of cement as the “glue” that holds the sand and gravel and re-bar (reinforcement bar) together to make concrete.
