Abstract.

The paper presents findings on electric field impact on process of extracting magneto-susceptible copper from the basalt raw materials consisting of three types of rock: basalt, tuff and longwall breccia. The three components contain different percentage of native copper which is, nevertheless, sufficient for efficient cooper extraction. In the paper, the author proves high effectiveness of using electric separation at the final stage of the basalt complex processing. Subject of the study was dependences between extracted copper concentrate output, electric field intensity in separator and size grades of the rocks fed for separation.

As a result of the study, correlation of dependences between native copper concentrate output, electric field intensity and size grades in three test samples of mined rock has been analyzed and regression models have been created for assessing the concentrate output.

Thus, effectiveness of using electrical separation at the final stage of the basalt complex processing has been proved.

Key words:

basalt, tuff, longwall breccia, native copper, electric separation.
