  1. 16.2 Minerals Exploration and Mining

  2. I. Mineral Exploration Steps to finding mineral deposits Exploration: Potential mining areas are monitored for differences in gravity, magnetism, radioactivity. This info coupled with photos creates a geological map b. Samples are taken from potential areas to be analyzed c. If everything checks out, a mine may be opened

  3. II. Types of Mining Subsurface mining LongwallMining – Large machine used to remove large deposits of coal

  4. Uses high pressure water to remove mineral deposits 2. SolutionMining – B. Surface mining Large machine used to remove large deposits of coal Surface Coal Mining –

  5. Building stones…granite, limestone, and marble 2. Quarrying –

  6. Recovery of sea salt through the process of evaporation 3. SolarEvaporation –

  7. Deposits of dissolved minerals in streams where the current is slow. Can be recovered by dredging 4. PlacerDeposits – Crushed ore melted and separated 5. Smelting –
