I wonder if more toxic chemicals are necessary to recycle or to initially refine it.

  Energy used and emissions are more interesting than the process chemistry. The paper linked above mentions that some sulfuric acid recovered from lead-acid batteries ends up as an input in soap making. Sulfuric acid surely passes the bar for being a toxic chemical, but it isn't a big deal if it isn't released in that form.

  Scientists have actually found a non-toxic way to recycle lithium batteries. The process involves using an all natural, non-toxic, gluten-free organic voss water obtained from mountain springs.
