Latest Patents

Leffler holds a patent for a process aimed at recovering rare metals from the combustion residue of coal. This invention involves a method of digestion, specifically through aqueous and/or dilute alkaline and/or dilute acidic digestion. The process allows for the combination of two or three digestion steps in any desired order or to be carried out separately. During the digestion, the concentration of the solution is monitored, and subsequent steps are terminated at a desired concentration. The solid and liquid phases are then separated, allowing for the isolation of rare metals from the liquid phase. The solid phase can be utilized as a source of energy after optional neutralization and/or washing.
