Dahl Process

摘要

The Dahl mining system is an environmentally safe, chemical free system that mines microscopic precious metals from head ore adding water and urea agitating this mixture until the precious metals are released from the head ore. Polymers are then added to the mixture and agitated until the polymers reach full hydration. The polymers are then screened from the mixture for the dehydration process. The extraction portion of this process begins by separating the metals from the polymers or bar in a controlled environment or room.

主权项

1. A method of an environmentally safe mining process through extraction of microscopic precious metals for the head ore comprising:
(a) releasing said microscopic precious metals by introducing water and nitrogen based fertilizer into said head ore while agitating the mixture; (b) introduce the polymers to said mixture and allow said polymers to absorb said precious metals while said agitation process continues; (c) screen said polymers from said mixture and allow complete dehydration of said polymers; (d) extraction of said precious metals from said dehydrated polymers now occurs in a controlled setting or room where said precious metals are separated from said dehydrated polymers with the use of chemicals which shall never be introduced into the environment.
