this time there is no detailed quantification of particle damage and downstream benefits from HPGR crushing are uncertain. In the present research, copper ores (copper oxide ore and copper sulfide ore) were crushed by a jaw crusher and by HPGR and the products were evaluated for particle damage and copper grain exposure by X-ray computed
The degree of crushing i is defined as the ratio of Dmax - the size of the largest pieces of rock in the material entering crushing, to dmax - the size of the largest pieces after crushing. i = Dmax/dmax. In turn, the crushing process is divided into stages of crushing in a crushing machine: large – from 1200 to 300 mm; average – from 300 ...
In the crushing process of copper ore processing, the two-stage-closed-circuit crushing-single-stage ball milling process is more common in small copper ore concentrators whose production scale is below 500t/d. Three-stage crushing is currently the most crushing and grinding process used by large and medium-sized copper ore concentrators.
Gyratory breakers of the Gates type have the advantage of delivering a very uniform product, and in crushing ores that are hard and dry this type forms by all odds the best initial crushing-machine; but with ores that carry wet clay, slate, or other substances which will "pack," it is necessary to use a swinging-jaw crusher, preferably of ...

the proximity of the plant; ore is transported by a network of conveyor belts while that from No. 3 Shaft, located about three kilometers away is transported by dump trucks which bring the copper ore to the stockpile where blending of the copper ore takes place. The ore has an average grade of 3.0%
steps) is expected to provide significant benefits to copper extraction efficiency via subsequent heap leaching due to mi- crofracturing within host rock particles and improved product
Advantages of copper ore gravity separation. 1. Copper ore gravity separation can improve the grade of copper ore. ... Crushing: Copper flotation process usually includes crushing, grinding, flotation and cleaning steps. Grinding: The ore is finely ground through the ball mill and other equipment to refine it into smaller particles.
The characteristics of copper ore, the distribution characteristics of crushing products, copper, and the occurrence characteristics of Pb in copper ore were investigated. The results show that more than 80% of copper is distributed at a density of +4.0 g/cm 3, and Pb exists in the pyrite.
Due to the different types of ore, the nature of the ore is also different, so the beneficiation process needs to be customized. The specific process for selecting copper ore depends mainly on the material composition, structure and copper occurrence state of the original copper ore. Generally speaking, copper ore can b…See more on ftmmachinery
