I downloaded a couple of old industrial chemical books on Google Books. I found another process. Instead of sodium nitrate, they used barium nitrate. The equation, otherwise, is about the same. It takes about 1.5 times as much weight of Ba(NO3)2 as it does NaNO3. The big difference is that Ba(NO3)2 is only about 10% as soluble in water as NaNO3.

This manuscript aims to investigate the impact of another sulfur containing anion on the process of barium sulfate crystallization. The rational behind the choice of this ion is that the sulfite ion is slightly stereochemically different to sulfate but has the same formal charge (see Fig. 1).One complication is that the sulfite ion can oxidise to sulfate in solution, however, this …

Herein, we conduct an in-depth investigation of the specific process that the Cl − influences lead removal by barium sulfate coprecipitation. Because of the complexation equilibrium in the tin chloride solution, the Cl − concentration was bound to affect lead removal during barium sulfate coprecipitation. To determine the behaviour and mechanism of lead …

Barium slag (BS) is a kind of industrial solid waste discharged during the refining of barite by the process of carbothermal reduction (Salem and Jamshidi, 2012).In the productive process of barium salt, barite is reduced to barium sulfide by coke or coal in a rotary kiln at about 1100 °C (Jamshidi and Ale Ebrahim, 2008; Salem and Osgouei, 2009).
