Application of the solution mining process to the Turkish ...

Aug 01, 1996  In the mid 1980s a new area in trona mining emerged and the FMC Corporation brought onstream additional soda ash capacity through the use of solution mining. Although the concept was not new, its application to trona was [2]. The end result of the application of solution mining was a reduction in trona mining costs [3-5].

About Us - Solution Mining

WHAT WE DO, Solution Mining Research Institute, Inc. "SMRI" SOLUTION MINING SIMPLIFIED is pumping of fresh water down a well to dissolve underground deposits of water soluble minerals like salt, potash, trona, etc. As the water circulates it dissolves the mineral and becomes saturated, the brine is forced up a separate pipe string to the surface.

Solution Mining Research Institute

Minerals such as salt, potash, trona, and magnesium salts may be produced by pumping saturated fluid from underground caverns. The caverns are created by pumping out the saturated 'brine' while pumping in fresh water as a controlled production process. The minerals are then recovered from the saturated fluid by recrystallization.

The Role of the Calciner in Producing Soda Ash

Processing Trona Ore into Soda Ash. The process of transforming trona ore into soda ash is relatively simple. And while various processing methods exist for processing trona ore into soda ash, two primary methods of a similar nature prevail: The Sesquicarbonate Method. In this method, trona ore is first dissolved in an aqueous solution.
