Bauxite Mining
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.
