    Ore. Ore is metalliferous rock that can be mined and processed at a profit. Although a broader definition includes nonmetallic rocks like rock salt and gypsum, most geologists classify these materials as industrial rocks and minerals.. History. Gold, silver, and copper artifacts left by prehistoric tribes and ancient civilizations attest to an interest in ores extending back to earliest times.

  • Advantages To Surface Mining Article

    Underground Mining For Meeting Environmental. Underground mining can be considered to be more acceptable than surface mining from environmental and social perspectives since, it often has a smaller footprint than an openpit of comparable capacity.The main advantage of underground mining compared to surface mining is that in general only the ore is extracted and waste rock is left behind.

    To make mining efficient and effective, the raw rock and soil are typically not examined onsite. Instead, they are transported to special plants where the ore is processed and the rough diamonds are extracted.
