The Bingham Canyon pit is 2.5 miles-wide and very deep. Mining uses a rotary drilling/blasting – shovel/truck – in-pit crushing system, with two to four blasts a day.
In hard rock mining, much of the world's annual output of copper, gold and iron ore is won from open-pit operations. Other commodities produced from open-pit mining include diamonds, molybdenum, manganese, lead and zinc, uranium and a variety of industrial minerals, such as borates, talc and specialist clays.
For copper mining, fuel consumption increased by 130% and electricity consumption increased by 32% per unit of mined copper in Chile from 2001 to 2017, largely due to decreasing ore grade.
Prior to mining, all rocks contained in a mineral deposit must be placed in one of several categories known as ore types. Each ore type describes a different way that the rock will behave in processing. The ore type determines which process stream a particular mined unit will be sent to, sets expectations for process engineers and …
