Mining value chains are highly complicated and must account for all assets, including equipment (for example, trucks and shovels), processing plants, and railway and port operations (Exhibit 1).
Open-pit panel mining has been the normal surface method since the early 1960s. A strip or block of bauxite is exposed and mined, and then another panel is exposed. The first panel is normally refilled with waste rock. Several panels typically were open at the same time to supply the proper blend of ores to meet mill specifications.

1.1.3.1 Open-pit mining Open-pit mining is a type of strip mining in which the ore deposit extends very deep in the ground, necessitating the removal of layer upon layer of overburden and ore. In many cases, logging of trees and clear-cutting or burning of vegetation above the ore deposit may precede removal of the overburden. The
In most mining plant, we just need in-plant conveyors. And the conveyor system may be very complicated. It often consists of many belt conveyors. We just list some of them below: 1. tripper conveyor car: used to …
Bauxite is generally extracted by open cast mining, being almost always found near the surface, with processes that vary slightly depending on the location. Before mining can commence the land needs to be cleared of timber and vegetation.
Metallic mineral processing typically involves the mining of ore from either open pit or underground mines; the crushing and grinding of ore; the separation of valuable minerals from matrix rock through various concentration steps; and at some operations, the …
