The finished extraction is referred to as “pregnant leach”.
This is sent to another tank for precipitation, typically a cone tank, so you can separate the heavy
solids which will fall to the bottom, and return the neutralized water to other uses.

In order to extract the Gold and other Precious metals from your Carbon slave units you will need tanks
in which to mix the extraction formula, recycle this through the carbon load until the majority of the
metals have been leached out. The carbon recovery tanks are leached one at a time in an array system
into a similar sized capacity tank. For a 300 gallon unit, a 300 gallon leach out tank is required.
This typically will be re-pumped over and over through the carbon with a magnetic drive electric pump,
capable of withstanding the chemical load imposed on the pump portion without damages.
