Advances in Pulsed Power Mineral Processing Technologies
Round 1
Reviewer 1 Report
The paper will be very useful reading and tool in the hand to scientists working in the presented scientific and technology field.
Around 50-55 % of references are self-citations by the authors. However, this is understandable since authors represent and have participated in further developing the scientific school (Plaksin, Shafeev, Chanturiya) that is practically pioneer and world lieder in the application of energy impacts on minerals with the aim to enhance valuable components recovery by subsequent treatment.
Although the paper practically could be published in the present form, some small ''technical'' corrections are proposed - see the attached file. Their consideration will facilitate the future readers.

Reviewer 2 Report
This review was reported the advances in pulsed power minerals processing technologies, especially in Russia. In their conclusion, the method of exposing gold-bearing and polymetallic ores to high-powder nanosecond electromagnetic pilses has significant advantages. This manuscript is relatively well written. But there are some issues which must be improved by the authors:
1. There are too many keywords, and What does ICEMR RAS mean? Please explain.
2. What does “deep mineral processing “ mean? It was well known that the mineral processing of complex ores is difficult.
3. In the section of 2.5.1, the correlation between paragraphs should be strengthened.
4. The energy consumption comparison between the different methods should be given.
5. Line 712-714, how did the authors prove that pulsed energy impacts can be used to improve the flotation performance of eudialyte and perovskite ores.

Dear Reviewer,
Thank you very much for your comments.
We took into account all your comments, and we made the changes to the paper text.
- We reduced the number of keywords; the abbreviations decoded and introduced in text, for example, the Institute of Comprehensive Exploitation of Mineral Resources Russian Academy of Sciences (ICEMR RAS).
- The term "deep processing" refers to the hydrometallurgical or chemical processing of concentrates or other enrichment products to obtain chemical compounds or metals.
In the case of complex polymetallic gold-bearing ores, the preliminary treatment of gold-bearing concentrates by HPEMP by creating breakdown channels in mineral complexes ensures the effective interaction of cyanide solutions with gold and, as a result, increases the extraction of gold into a productive solution with its subsequent direction for precipitation or electrolysis.
We made changes to the paper text - p.2 - deep mineral processing of mineral raw materials.
- We tried to improve the relationship between paragraphs in the section of 2.5.1.
- The energy consumption comparison between the different methods should be given.
Earlier in [3,4] (Tables 1) we summarized the basic technological effects, including energy consumption for different nontraditional (nonmechanical) energy effects and processes for disintegration of mineral complexes based on experimental data obtained in Russia and globally.
We added energy consumption values for each method in the text of this our paper.
- Line 712-714, how did the authors prove that pulsed energy impacts can be used to improve the flotation performance of eudialyte and perovskite ores.
This fact is confirmed by the results of flotation experiments presented in [106,109]. As a result of preliminary short-term (ttreat = 30 s) electromagnetic pulse treatment of eudialyte rough concentrate the eudialyte recovery in a flotation increased by 15% (from 48% at ttreat = 0 s to 63% at ttreat = 30 s). The effect of HPEMP and DBD on the physicochemical properties of the perovskite surface represents a shift in the electrokinetic potential towards positive values, an increase in the contact angle (ttreat = 10-30 s), as well as the improved adsorption of the collector and the higher flotation recovery of perovskite by 10–15% [109].
