Round 1

Reviewer 1 Report

In Figure 2, how does the author judge the chrome sulfide spinel mineral without chemical mineral composition detection?

Why is there no data supporting the separation effect in the abstract of the experiment of separating chromium sulfide spinel from reduced ilmenite?

Why is the flotation concentrate yield in Table 3 so low? What is the purpose of flotation in this paper?

What about the chemical analysis results of flotation concentrate in Table 4?

Figure 13 shows the surface scan map of flotation tailings. Is there any surface scan map of flotation concentrate?

The content of the conclusion is very bloated and not concise enough. I propose to delete it.
