Cement, How It Is Produced Mine Engineer.Com

Cement, or Portland cement, is defined as "a hydraulic cement, obtained by burning a mixture of lime and clay to form a clinker, then pulverizing the clinker into powder. The greenish gray powder is composed primarily of calcium silicates, calcium aluminates, and calcium ferrites.

The Actual Difference Between Surface and Underground Mining

In most underground mining methods, deep vertical tunnels called shafts are drilled into the ground, along with a set of horizontal tunnels called drifts from the shaft bottom to access the ore. Then, longwall and continuous miners break up the ore deposit, which is transported back to the surface by conveyors.
