The Soda Ash Business
There are two general methods of mining soda ash naturally. The first, called solution mining, is a method which involves pumping a solution into well lines within sodium carbonate, also called trona ore, deposits. The trona ore is dissolved and pumped out. The solution is then processed and the soda ash is isolated.
