Industrial Chemical Hydrochloric Acid Price,With Good Mining industry,Oil drilling,Metallurgy,Dyeing,Food industry Hydrochloric acid is used primarily for continuous pickling operations in which is used to regenerate the ion exchange resins that are employed to remove . ...
The Mt. Taylor IX Plant is designed to treat 10,000 gpm of mine water for removal of uranium. The ion exchange process for recovering uranium from mine water utilizes a quaternary amine incorporated onto a porous styrene divinylbenzene bead. The amine has the ability to give up anions in exchange for anions in solution, in this case,'' uranium.
Bufflex) and the introduction of continuous countercurrent ion exchange (CCIX). Column SX has found a ready application to uranium in view of the rapid extraction kinetics. With the renewed interest in uranium processing, efforts are being redirected towards further development of resininpulp (RIP) as a means of driving down capital and ...
ISR mining technology was developed independently in both the Soviet Union and the United States in the mid1960''s. The method was developed to extract uranium from typical roll‐front type deposits (a sub‐type of sandstone uranium deposits) located in water‐saturated permeable sediments that were not suitable for economical conventional mining techniques.

In 2010 Uranium Energy Corp. began an ISL mining operation in the Palangana deposit in Duval County, Texas. The ion exchange facility at Palangana trucks uraniumloaded resin beads to the company''s Hobson processing plant, where yellowcake is produced. Uranium Energy Corp. has three additional South Texas deposits permitted or in development.
The uraniumrich solution is pumped from the ore zone to the surface and circulated through a series of ion exchange columns located at the mine site. The solution flows through resin beds inside an ion exchange column where the uranium bonds to small resin beads.
At the Schwartzwalder Mine in Colorado, resins were used to recover uranium from mining and metallurgical processes (Zielinski et al. 2008). Other tests of ion exchange with mining influenced waters are referenced in Gusek and Figueroa (2009). 3. Advantages Advantages of ion exchange include the following:
