Solution Mining. Solution mining is a mining method of dissolving and extracting minerals by injecting fresh water into underground deposits and taking advantage of the characteristics that halite, potassium salt, trona, and mirabilite that are easily soluble in water. In 1888, New York began to use the solution mining process after halite was ...

In solution mining, dilute sodium hydroxide (NaOH), commonly called caustic soda, is injected into the trona to dissolve it. This solution is treated with carbon dioxide gas in carbonation towers to convert the sodium carbonate (Na 2CO 3) in solution to sodium bicarbonate (NaHCO 3), which precipitates and is filtered out. The crystals

Trona can be mined primarily through two methods: mechanically and through Solution mining. Mechanical mining uses a bore miner that removes the trona ore from the ground and sends it to the surface using conveyor belts and bucket elevators. Solution mining is achieved by pumping water into the trona ore, dissolving it to create a solution, and ...

What is Solution Mining? Solution mining is the process of extracting underground, water-soluble minerals (salt, potash, trona, etc.), through one or more drilled wells, by dissolving the minerals with water. 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 avoids the risks associated with conventional underground mining methods by taking advantage of trona's natural water solubility. Because water does the work, trona can be brought to the surface without additional chemicals, and without sending personnel and equipment underground.
