Primary Crushing Mineral Processing & Metallurgy

Mar 17, 2017 The term “primary crusher,” by definition, might embrace any type and size of crushing machine. The term implies that at least two stages of crushing are involved, but in many cases the machine which performs the function of initial crusher is the only crusher in the plant. The factors influencing the selection of a crusher for this service

Low-grade ore is ball-milled before being agglomerated and dump-leached to recover its copper content. the bulk of the primary crusher output (63,500t/d of ore) is secondary crushed and conveyed to the Stargo dump-leaching site. Copper production in 2011 stood at 614 million pounds. The mine produced 514 million pounds and 504 million

ASARCO » Mining

A number of mine plans based on different metal prices can be developed to help the mine better respond to changing market conditions. When the price of copper is high, lower-grade ore can be cost-effectively mined along with the better grade ore. When the price is low, the mining operations can focus on the higher grade ores.

Optimization of primary gyratory crushing at Highland

Haib Copper Deep-South Resources

The primary reasons for the selection of heap leaching are the low-grade nature of the deposit and the vast scale of the mineral body. Previous work conducted on the Haib Project suggested that a conventional crush-grind-float and sale of copper concentrate is not economically feasible under the current copper market conditions.

Liner wear and performance investigation of primary

Nov 01, 2004 Liner wear directly impacts the gap dimension as well as the chamber profile ( Bearman and Briggs, 1998, Svensson and Steer, 1990, Westerfeld, 1985 ). Hence, liner wear is an important variable in the overall crushing operation as it is intimately related to product quality (size consistency and throughput) and cost.

Copper Mining and Processing: Processing Copper Ores

Copper processing is a complicated process that begins with mining of the ore (less than 1% copper) and ends with sheets of 99.99% pure copper called cathodes, which will ultimately be made into products for everyday use.The most common types of ore, copper oxide and copper sulfide, undergo two different processes, hydrometallurgy and pyrometallurgy, respectively, due to the different

Viewpoint Mining Magazine Building a world-class mine in

The ore body will be uncovered through erosion by the Asana River, leading to a low strip ratio. The central location of the primary crusher will allow short haulage distances, with a downhill loaded cycle for most of the first 10 years. This enables the mine to operate with a smaller fleet and low consumables.
