Title: The Innovative Contributions of Roger L Day
Introduction
Roger L Day is a notable inventor based in Rifle, Colorado, who has made significant contributions to the field of solution mining. With a total of 15 patents to his name, Day's work focuses on innovative methods and compositions that enhance the extraction of valuable minerals.
Latest Patents
One of Roger L Day's latest patents is centered around trona solution mining methods and compositions. This invention discloses a method of solution mining trona by injecting an aqueous solvent into an underground cavity containing trona. The process involves dissolving trona in the aqueous solution and subsequently removing the solution from the cavity at approximately the WTN triple point. This temperature allows for the coexistence of solid phases such as wegscheiderite, trona, and nahcolite in an aqueous solution. The alkaline values extracted from the removed solution are then recovered to produce a barren liquor. Furthermore, the method includes options for treating the barren liquor to generate an aqueous solvent or treating the injected aqueous solvent to minimize clogging at the trona dissolution surface, which can occur due to supersaturation of sodium bicarbonate and the precipitation of nahcolite and wegscheiderite.
