How to Find Ore and Mineral Deposits - Geology ...

Mineral exploration is the process of finding ores (commercially viable concentrations of minerals) to mine. Mineral exploration is a much more intensive, organized and professional form of mineral prospecting and, though it frequently uses the services of prospecting, the process of mineral exploration on the whole is much more involved.

How do mining companies find mineral deposits? Socratic

Feb 19, 2016  Primarily through prospecting and exploration. In the past centuries, many mineral deposits were located by amateur prospectors going into the bush and basically looking around! If they found a promising deposit, they would officially stake it with the government and then try and interest a mining company in buying it. Today, while there is still some prospecting going on, exploration is ...

Mineral deposit Britannica

All ore deposits are mineral deposits, but the reverse is not true. Ore deposit is an economic term, while mineral deposit is a geologic term. Whether a given mineral deposit is also an ore deposit depends on many factors other than the level of concentration and the size of the deposit; all factors that affect the mining, processing, and transporting of the ore must be considered as well.
