Development of copper recovery process from flotation

2018. 6. 15.· Sulfide copper mineral, typically Chalcopyrite (CuFeS 2), is one of the most common minerals for producing metallic copper via the pyrometallurgical process.Generally, flotation tailings are produced as a byproduct of flotation and still consist of un‒recovered copper. In addition, it is expected that more tailings will be produced in the coming years due to the increased exploration of low

Evaluation of the possibility of copper recovery from

2018. 1. 10.· The evaluation of flotation method to recovery copper from tailings has been conducted. • The application of novel depressant (NDAD) and collector (COES) exhibited excellent performance. • The promotion of technology not only benefits a company but also minimizes the impact of mineral processing on environment.

RECOVERY OF COPPER FROM COPPER SLAG AND COPPER SLAG

Abstract: Copper smelter slag and copper smelter slag flotation tailings were leached using sulphuric acid solutions, without or with the addition of either ferric sulphate or hydrogen peroxide. Copper extraction from the slag was typically found to be twice as high as that from the slag flotation tailings.

Copper Tailing an overview ScienceDirect Topics

Copper tailings are a finely ground waste after copper mineral has been extracted from the ores during beneficiation. Similar to CS, the use of copper tailings as a geotechnical material has also been reported in the literature, but on a relatively smaller scale (Collins and Ciesielski, 1994; Gupta and Thomas, 2013; Nitish et al., 2013; Miller

New approaches for extracting and recovering metals from

2017. 5. 15.· Mine tailings may contain base transition metals, such as iron, copper, nickel and zinc, in relatively high concentrations, and also occasionally precious metals such as gold and silver, in minerals (and native metals) that have been not been separated by froth flotation (e.g. Bryan et

Copper Leaching from Refractory Flotation Tailings

2018. 5. 3.· copper sulfide and free oxidation copper in the raw ore were recycled by flotation, but the other refractory copper oxides, mainly the combination copper oxide, were not thoroughly recycled and the majority were lost in the tailings. As is typical for flotation tailings containing silicate gangue minerals, high temperature leaching was used [12].
