http://www.bosssafety.com/p-6802-3m-half-facepiece-assembly-wfilter.aspx This will work as long as you aren't in an enclosed space without dust extraction. These only work if you wear it properly and test it.

I'd appreciate some clarification: this mask recommended solely because the selected media is non-silica?

I would use the same if it were silica sand. The reason you need an open environment or dust extraction is because when the atmosphere is full of heavy dust it can 1) find its way into the exhaust valve of the mask causing it to hang open allowing contaminated air to be drawn in and 2) the filters become clogged easily and youn either have to replace them very frequently or you end up pulling contaminated air past the face seals. If you sand blast in an enclosed area or one without dust extraction then you need a supplied air system.
