Eco-Pioneer Washing Soda is derived from solution mining of natural, trona mineral deposits. Solution mining offers a process by which sodium products can most efficiently be extracted from ore deposits. The trona ore is dissolved in a water solution creating a brine. The brine is processed to recover sodium carbonate (washing soda) and other sodium products. The sodium depleted brine is recycled to the trona ore deposit to dissolve additional trona and reduce waste water production.
