The impact of more data-empowered decision making was seen at Freeport-McMoRan's copper mine in Arizona, where AI modelling of grinding circuit operations has helped to improve mill productivity by an estimated 20 million lb. per year – an increase that has allowed the company to avoid most of planned $200 million capital expansion.⁶

The mine uses two semi-mobile in-pit crushers to minimise haul distances. Several kilometres of conveyors carry up to 12,000t/h of crushed ore to three stockpiles at the Highland mill. Pit operations are monitored and controlled by a Modular Mining Systems computerised dispatch system designed to maximise mine production.

Mine conveyors for productivity and profits. Conveyors have long been referred to as the arteries of a mining operation – critical to the movement of material through the system. If the conveyors stop, the mine stops; it's as simple as that. We are the leaders in designing and building mine conveyor systems that will increase your ...

Crushers play an important role in the material handling process for underground mine operations. The main purpose of a crusher is the size reduction of the feed. This size reduction is achieved by applying a force to the material, creating cracks in the material which in the end will cause the material to break into smaller pieces.

Grasberg has produced 528 billion ounces of copper and 53Moz of gold during the period between 1990 and 2019. The mine is jointly owned by Freeport McMoran (48.8%) and Inalum (51.2%).

The Bingham Canyon copper mine in Utah is the world's largest human-made excavation. Like most large open-pit mines, Bingham's walls are terraced to reduce landslide risk and enable heavy equipment to reach mineral-bearing rock. Vertical faces are called "batters," horizontal surfaces are "benches."

Gyratory Crusher: This type of crusher is used for primary crushing of large copper ore. Gyratory crushers are designed to handle high-capacity operations and are ideal for ore with a high hardness.

The crusher was completely assembled, the hydraulic systems were checked, and the crusher was run no-load to check operation at the anticipated speed and throw combinations. Strain gage testing was also done using a simulated crushing load. This work confirmed our finite element analysis and the crusher was shipped to site.

The blast holes are filled with a mixture of ammonium nitrate and fuel oil (ANFO) type explosive. Most mining operations use nonelectric caps and delays to control the blasting sequence. Usually, an entire segment of a bench is "shot" at one time. ... Copper shows a typical jaw-type crusher. Cone crushers, shown in Figure l-5b, work best at ...

The essential task of the in-pit crusher in a belt conveyor transport system is to reduce blasted material to a conveyable size. Crushers for this purpose are almost exclusively of the low crushing ratio type (up to 1 : 10), i.e. so- called primary or pre-crushers, designed as mobile or semi-mobile units.

Facility location models are rarely used in the mining sector, but these models may be used for solving the in-pit crusher location problem. To this end, the main parameters affecting the IPCC location in open pit mines are reviewed and examples given of how they are applied to a dynamic location-relocation problem. Subsequently, the model is ...

A review on the design and operations challenges of a single toggle jaw crusher is presented. Strength and fracture toughness of the material to be crushed are intrinsic properties that determine ...

The product of these two stages of crushing and screening then passes to secondary milling. In hard-rock metals mining applications, HPGRs are currently in use in tertiary and quaternary crushing applications, as well as in secondary pebble crushing. In many respects, HPGRs replace crushers as a unit operation. However, from a process …

A Copper Flotation Flowsheet. Because the copper in this type of ore usually assays only plus or minus 1% copper, the porphyry copper operations must be relatively large in order to be commercial. The flowsheet in this study illustrates a typical 3,000 ton per day operation. In general most operations of this type have two or more …

Block caving is an underground mining method that uses gravity to exploit massive, steeply dipping ore bodies located at depth. These ore bodies are generally low grade in nature and are too deep to be extracted through open pit mining. The technique is commonly used to extract low grade copper, copper-gold, iron and molybdenum ores …

They are used in mines and quarries as primary crushers to crush blasted rockpile, which may have edge lengths of over 2,000 mm depending on the blasting method, in preparation for finish crushing or conveying.
