Reviewer 1 Report
The manuscript entitled "Mining Residues Characterization and Sentinel-2A Mapping for the Valorisation and Efficient Resource Use by Multidisci-plinary Strategy”, submitted to minerals, may be considered accepted due to the following reasons.
In this research, Sentinel-2A image classification combined with hyperspectral signatures and mineralogical, physical and chemical characterization analysis, has produced a map of mining residues. The results prove the ability of this multidisciplinary strategy to map the minerals of interest contained in mining waste. The references are suited, the manuscript is completed, the results are meaningful. Therefore it is suggested that it is suitable to be published in journal minerals.

Reviewer 2 Report
The proposed article describe a research with remarkable potential impact, based on state of art processes using state of art instruments. It also demonstrates a good control of probable errors.
The reviewer suggests the following corrections:
Line 54: Replace “resilience” with “resilient”
Line 109: ASD is the acronym for?
Line 253: Delete extra space
Line 251: Elements describing the mineralogical composition of the 100 samples should be listed following the percentage of concentration, from the highest value to the lowest.
Line 257: Same as above

Figure 9: Images and correspondent description not clear.
“Appendix B” repeats all the images' description in the article. Redundant.
Line 356: “D” should not be in bolt

Reviewer 3 Report
The paper written by the following Authors: Daniela Guglietta, Aida Maria Conte, Matteo Paciucci, Daniele Passeri, Francesca Trapasso, Rosamaria Salvatori, entitled “Mining Residues Characterization and Sentinel- 2A Mapping for the Valorisation and Efficient Resource Use by Multidisci- 3 plinary Strategy” presents an interesting study on a mining residues by multidisciplinary strategy in order to valorise and promote an efficient resource use.
Although the paper is interesting, I have some major concerns:
Title
The title reflects the results presented here.
Abstract
The abstract is lacking the aim of the study, material and methods description as well as an informative conclusion. It should be written in more details.
Material and Methods
- What was the reason for an optimized man- 118 agement of Fe and Mn-rich residues in the Indian mine area of Joda West?
- Figure 2 has too small legend. It should be corrected.
- Description of applied setup should be placed in the manuscript.
Discussion
- Presented results should be compared to the results of other scientists, presented in the manuscripts from the same field.
- In the discussion part three is no limitation to the studies. It should be included in the manuscript.
