Copper ore with a particle size between 0–1 mm was used in the experiments. A model was created that determines the relationship between the processing time and efficiency of the grinding, and can be used for the optimization of the process. A comparison of the relative growth of particle size fractions in milling products was performed.
· Copper ore beneficiation methods. Before the beneficiation of copper ores, crushing and grinding are required. The bulk ores are crushed to about 12cm by a jaw crusher or a cone crusher. Then the crushed materials are sent to the grinding equipment, and the final particle size of the copper ore is reduced to 0.15-0.2mm.

For instance, at Lornex Mining, one of the most successful SAG installations, the ball load varies normally from 6-7% by volume of the mill; the ball make-up consists usually of 80% 4-inch diameter balls and 20% 5-inch diameter balls. The ratio of the larger balls is increased when the mill is processing hard ore and decreased with soft ore.
According to the Coalition for Eco-Efficient Comminution, comminution – the process of crushing and grinding ore – is by far the most energy consuming step in the mining process. It accounts ...

The Boddington copper gold ore is of similar rock competency to that selected for this study and thus provides ...
Several authors have demonstrated improved liberation on copper sulphide, iron sulphide and native gold-containing ores after microwave treatment and subsequent grinding (Amankwah et al., 2005, Andriese et al., 2012, Wang and Forssberg, 2005).Other studies have also demonstrated increased flotation recovery and concentrate grade attributed to enhanced …
The refurbishment of the processing plant is now largely complete, and commissioning has commenced with the first successful float of copper concentrate. The primary crusher is now fully operational, coarse ore bins are full, grinding is running in batches and flotation is being tested.
Copper ball mill, sometimes called copper ore ball mill or copper mine ball mill, is indispensable grinding equipment in the process of copper ore beneficiation, and it occupies a very high share in the copper processing industry.The copper mine is a common metal mine. With the continuous development of science and technology, the comprehensive utilization value of …
10%Fine grinding, to P80 sizes as low as 7 μm, is becoming increasingly important as mines treat ores with smaller liberation sizes.This grinding is typically done using stirred mills such as the Isamill or Stirred Media Detritor. While fine grinding consumes less energy than primary grinding, it can still account for a substantial part of a …

energy required which in this case was to grind the ore represented by the samples, from a feed size F80 of 152 mm to 80% passing 1.7 mm, and a simple adjustment procedure in case the SAG product size needed to be adjusted. Bond rod and ball mill work indices are readily converted to pinion energy for rod and ball mills but not for SAG mills.

This eliminates the need for ultrafine grinding, high temperatures and high pressure which makes it energy saving and very cost-effective. In copper, the existing ore bodies are becoming lower grades, they are deeper, and they are more complicated to process. The ROL technology makes it possible to recover more copper from low-grade concentrates.
