1. Please ensure that your manuscript meets PLOS ONE's style requirements, including those for file naming. The PLOS ONE style templates can be found at 

https://journals.plos.org/plosone/s/file?id=wjVg/PLOSOne_formatting_sample_main_body.pdf and 

https://journals.plos.org/plosone/s/file?id=ba62/PLOSOne_formatting_sample_title_authors_affiliations.pdf

2. We note that the grant information you provided in the ‘Funding Information’ and ‘Financial Disclosure’ sections do not match. 

When you resubmit, please ensure that you provide the correct grant numbers for the awards you received for your study in the ‘Funding Information’ section.

3. We note that you have indicated that there are restrictions to data sharing for this study. PLOS only allows data to be available upon request if there are legal or ethical restrictions on sharing data publicly. For more information on unacceptable data access restrictions, please see http://journals.plos.org/plosone/s/data-availability#loc-unacceptable-data-access-restrictions. 

Before we proceed with your manuscript, please address the following prompts:

a) If there are ethical or legal restrictions on sharing a de-identified data set, please explain them in detail (e.g., data contain potentially identifying or sensitive patient information, data are owned by a third-party organization, etc.) and who has imposed them (e.g., a Research Ethics Committee or Institutional Review Board, etc.). Please also provide contact information for a data access committee, ethics committee, or other institutional body to which data requests may be sent.

b) If there are no restrictions, please upload the minimal anonymized data set necessary to replicate your study findings to a stable, public repository and provide us with the relevant URLs, DOIs, or accession numbers. For a list of recommended repositories, please see

https://journals.plos.org/plosone/s/recommended-repositories. You also have the option of uploading the data as Supporting Information files, but we would recommend depositing data directly to a data repository if possible.

We will update your Data Availability statement on your behalf to reflect the information you provide.

4. When completing the data availability statement of the submission form, you indicated that you will make your data available on acceptance. We strongly recommend all authors decide on a data sharing plan before acceptance, as the process can be lengthy and hold up publication timelines. Please note that, though access restrictions are acceptable now, your entire data will need to be made freely accessible if your manuscript is accepted for publication. This policy applies to all data except where public deposition would breach compliance with the protocol approved by your research ethics board. If you are unable to adhere to our open data policy, please kindly revise your statement to explain your reasoning and we will seek the editor's input on an exemption. Please be assured that, once you have provided your new statement, the assessment of your exemption will not hold up the peer review process.

5. Please amend the manuscript submission data (via Edit Submission) to include author Chaoyi Chen.

Title: Research on desiliconization of brown corundum fly dust and baux2 ite based on roasting-alkali leaching method

Authors: Nian Liu et al.

I cannot find keywords; Authors should improve add this information.

Line 48-64. There is no detailed description of the methods with indication of technological parameters (temperature, concentration of reagents, duration of the process and metals extraction degree). It is recommended that the authors add numerical values to the text of this section.

Table 1. Add the LOI content, what is the CaO, MgO, Na2O content? Add the carbon and sulphur content for the BCFD sample.

Authors should use “min”, “desilication”, not “minutes” and “desiliconization”.

Section 2.1. Add information about particle size distribution of the raw materials.

Table 2. Add the LOI, CaO, MgO content.

Add the information about chemical composition (g/L) after alkali leaching. Write the options for treatment this solution using the links.

Add information about particle size distribution of the sample after desilication.

What is the yield of the sample after roasting, and after desilication? Add this information to the article text.

Figure 1. Add the chemical formulas of the minerals.

Figure 3. Add the error bars to the columns and experimental points.

Figure 3d, 7. Sign peak at 20 degrees.

Figure 8. A very common mistake was made in the calculations. The curves do not pass-through point 0, it simply is not there. This is a mistake; you need to redo the calculation. You can read more information here: Levenspiel O. Chemical Reaction Engineering. https://the-seventh-dimension.com/images/textlev/LEVENSPIEL%20Chemical%20reaction%20engineering-ch1-ch2.pdf

Authors should add the final flowsheet with the optimum technical parameters.

Reviewer #2: This paper used low-grade bauxite mixed with solid waste (Brown corundum fly dust) for desilication to obtain a desilicated concentrate with a high alumina-to-silica ratio. It not only avoids the problem of solid waste stockpiling, but also makes the solid waste and low-quality bauxite turn into high-quality raw materials with high alumina-to-silica ratios, which has a good research value. However, the article still suffers from the following problems and revisions are recommended.

1. Picture clarity is low, need to improve picture quality.

2. It is suggested that some expressions be modified, for example, in line 117, “As shown in Fig 4(c)(d),” it is suggested that it be modified to read “”As shown in Fig 4(c) and (d)“”.

3. In line 69, the two sentences are not separated. For example:“Ding [21] treated the BCFD with ultrasound, and when the sulfuric acid concentration was 25 wt%, the gallium leaching rate was 82.56% Xiong [22] proposed .......”，It should be modified to：““Ding [21] treated the BCFD with ultrasound, and when the sulfuric acid concentration was 25 wt%, the gallium leaching rate was 82.56% . Xiong [22] proposed ......”

4. There is a sign error in line 204, for example:“solubility of alumina.[26, 27]. ”Suggested revision to“solubility of alumina [26, 27].”

5. Why choose 1050℃ for roasting activation temperature?

6. The desilication product XRD pattern suggests the addition of a standard card.
