open pit iron ore mining process

Open Pit Mining an overview ScienceDirect Topics

open-pit mining Mining. a method of mining in which the surface excavation is open for the duration of mining activity, employed to remove ores and minerals near the surface by first removing the waste or overburden and then breaking and loading the ore. Used to mine thick, steeply inclined coalbeds and also used extensively in hard-rock mining for metal ores, copper, gold, iron, aluminum, and other minerals.

Everything You Need To Know About Open Pit Mining

2018-11-1 · Open pit mining is one of mankind's greatest achievements in the ongoing search for precious ores such as copper, silver, iron, and gold. It describes the process of systematically excavating land and digging out the rocks and minerals in search of metallic ores and removing them via borrow or open pit.
