amount of shale in the flotation concentrate leads to a decrease of beneficiation effi-ciency. This also leads to an increase of unwanted elements such as arsenic, lead, or-ganic matter in the concentrate. Greater amounts of shale complicate copper ore con-centration process and cause lower copper recovery at the assumed concentrate grade

The production process of the Miduk concentration plant is considering crushing, material transfer units, material classification, flotation (Flotation air is provided by low pressure blowers for the

Innovative Methodology For Comprehensive Utilization Of ...

In order to utilize the waste, a novel process to recover the copper from the spent bricks by flotation was developed. The mineralogical characteristics of the bricks, the mechanisms of metal penetration, and the effects of grinding time, emulsified kerosene dosage, collectors, and Na 2 S addition on the copper recovery were investigated. The results indicated that the spent bricks were mainly composed of …

Flotation To Recover Copper Minerals From A Low

Flotation results show that the combined processing technology is efficient in utilizing the low grade rocks. A copper concentrate assaying 20.68% Cu at the recovery of 80.11% can be obtained, when the raw material assays 0.79% Cu.
