In each of these mining methods, various earthmoving equipment including shovels, dozers, hauling trucks, and loaders are used to remove and transport the ore. However, the first step is to loosen the rock in the ore body so that it can be moved and processed. Blasting and grinding equipment are used to accomplish this task.
Because marine deposits are distributed over large areas unevenly, mining companies utilize different methods to mine them. Some of these methods include shallowwater mining, deep sea operations involving high tech equipment and simple alluvial mining. Like open pit mining, the ore materials are usually transported offsite for further processing.
