Description:
WHAT I CLAIM AS MY INVENTION IS:

1. The process of harvesting, separating, concentrating, precipitating, refining and purifying a soluble salt consisting of removing the salt in solution from the bed or lake in which it is found, thus leaving behind the insoluble impurities, raising the solution of the salt to a height, spraying the said solution by suitable nozzles through the air and allowing the drops to fall a suitable distance so as to remove water by evaporation and lower the temperature of the solution, thus precipitating the said salt and removing the remaining impurities by draining off the mother liquor.

2. The process of harvesting, separating, concentrating, precipitating, refining and purifying sodium sulphate, consisting of removing the sodium sulphate in solution from the bed or lake in which it is found, thus leaving behind the insoluble impurities, raising the solution of the said sodium sulphate to a height, spraying the said solution by suitable nozzles through the air and allowing the drops to fall a suitable distance so as to remove the water by evaporation and lower the temperature of too solution, thus precipitating the said sodium sulphate and removing the remaining impurities by draining off the mother liquor.

3. The process of increasing the concentration of sodium sulphate in brine or solution by forcing it through nozzles and spraying it through the air, permitting the drops to fall into a container.

4. The process of removing soluble impurities from natural sodium sulphate deposits by removing the sodium sulphate in solution, forcing the solution through nozzles and spraying the solution through the air, permitting the drops to fall into a container, thus precipitating a portion of the sodium sulphate, allowing the solution to cool to precipitate the remaining sodium sulphate and finally draining off the mother liquor containing other salts which have not reached their precipitation point, thus removing the more soluble impurities.

5. A process for harvesting sodium sulphate by removing the same from its natural a source in solution during warm weather, thus leaving behind the insoluble impurities, pumping the brine into a container and allowing the brine to remain in the container until it cools to a suitable temperature, thus precipitating the sodium sulphate, and draining off the mother liquor containing other salts which have not reached their precipitation point, thus removing the more soluble impurities.
