What Are The Key Methods Used in Underground Mining to Extract Rare Metals?
Extracting rare metals from underground mines requires specialized methods and techniques tailored to the nature of the ore bodies and the location of the deposit.
Shaft Mining
Shaft mining involves sinking vertical tunnels deep into the earth to reach ore deposits. This method is often used when mineral deposits are located far below the surface.
Drift Mining
Drift mining is used for ore deposits that are close to the earth’s surface. Horizontal tunnels, or drifts, are dug to reach these deposits.
Block Caving
Block caving is a more advanced technique used to extract ore from deep underground. It involves removing large sections of the ore body, causing the rock above to collapse. This method is highly efficient for extracting bulk metals like copper and gold, but it can also be applied to certain rare metals.
Cut and Fill Mining
This method is used in steep, irregular ore bodies. It involves excavating the ore in slices, filling the empty space with waste materials to maintain ground stability.
