''m not saying this is the actual chemical process, by the way – just an example of how chemical combinations can make something deadly or delicious. When the toxins are metals, of course, they cannot be broken down into other elements any more than lead could be changed to gold. Some plants can absorb the metal and metabolise it into some

When using a variable speed wheel, this split should be processed at the slowest speed, and the pitch of the wheel should be set at a steeper angle. Use a moderatetoslow water flow, adjusting the wheel to pull just a little black sand, and all the gold. Once you''ve run it through, simply adjust the wheel a bit steeper and rerun this gold
