Copper (Cu) Ore Minerals. Copper (Cu) ore minerals are naturally occurring compounds that contain copper in various chemical compositions. Copper ore minerals are typically found in rocks and mineral deposits and serve as the primary source of copper for industrial use. Some common copper ore minerals include: Chalcopyrite: Chalcopyrite …
Crushers. Industrial crushers reduce large rocks, ore or waste materials to smaller sizes by impact or pressure to fracture or deform the material. During the primary crushing operation, boulder size feeds from 20 to 100 in. are reduced to secondary crusher sizes of 1 to 20 in. or mill feed size of .5 to 3 in.
Gyratory crushers are used in mine or ore processing plants and they can be used for primary or secondary crushing. It crushes rocks by rotating the vertical shaft and crushing the rocks in a circular motion where they fall out the narrow bottom when they are small enough.A gyratory crusher is used both for primary or secondary crushing.

Primary Crushing. The purpose of the primary crusher is to reduce the ROM ore to a size amenable for feeding the secondary crusher or the SAG mill grinding circuit. The ratio of reduction through a primary crusher can be up to about 8:1. Feed: ROM up to 1.5 m; Product: -300mm (for transport) to -200mm (for SAG mill) Feed Rate: 160 to 13,000 tph
Blake type crushers come in various sizes and are commonly used for primary and secondary crushing roles. How Jaw Crushers Are Sized. Jaw crushers are sized based upon the dimensions of the top feed inlet (gape) or the dimensions of the jaws. For example, a 32 x 54 sized jaw crusher will measure 32 inches from the movable to stationary jaw ...
All types of crushers are widely used in gravel and aggregate fields, and they are often put in use after the excavation and blasting processes. Although their common and basic function is reducing large size of rock into small size, they are applied to different crushing stages like primary, secondary, tertiary, quaternary stages.
