That seems completely unrelated to the article. nobody is proposing aerosol anything here.
> Using huge tracts of land to purposely alkalinize the soil is going to create issues with the land and riverine environment and local ecology.
The huge tracts of land are already effectively ruined by agriculture; They are not proposing to do this over virgin plains or forests. The soil is already acidic, and historically they have been using limestone to increase the pH to make it suitable for crops, so some amount of alkalinity is actually desirable here. It's mentioned in the publication that they (paraphrasing) understand the impacts of adding some alkalinity to the soil, the target result is a more neutral pH, and they are aware of the consequences of over-applying it.
As far as pH management goes, it's unlikely to be any worse than the limestone they have already been working into the fields for decades.
> and silicosis being an ongoing threat for wildlife and nearby humans
This is also addressed in the report. They are specifically selecting basalt for the higher mineral:silica ratio and low toxic metal content which minimizes the risks.
> And in areas where acid rain is present, quick reactions can release the Carbon dioxide right back into the atmosphere
It's unclear where the carbon is coming from that's not already in the form of carbonic acid (CO2 dissolved in rainwater). The entire process works because the acidic rain reacts with the minerals to produce stable carbon compounds, so it's not immediately clear how or why the sane acidic rain that the reaction relies on would undo that reaction. There is no appreciable amount sodium in the minerals being spread either, so I have no idea why you're mentioning sodium carbonate or where it's coming from.
> I reviewed the chemical process of that in another post.
Well, you addressed chemistry but I didn't see anything relevant to this situation. Maybe you should re-read the articles relevant to the topic and consider what parts of your arguments are and aren't applicable. (Hint: Sodium bicarbonate is not relevant.)
