14 Apr 1971TL;DR: In this article, a process for benefiting from the trona ore for the development of sodash is described, which is based on CRUSHING the ore, SEPARATING the Ore by OPTICAL-MECHANICAL SORTING MEANS, RECOVERING the desired TRONA ORE FRACTION and CONVERTING SAID BENEFICIATED FRACTION to SODA ASH by IRCULATION.
Abstract: A PROCESS FOR BENEFICIATING TRONA ORE FOR PRODUCING SODA ASH, WHICH COMPRISES CRUSHING THE ORE, SEPARATING THE ORE BY OPTICAL-MECHANICAL SORTING MEANS, RECOVERING THE DESIRED TRONA ORE FRACTION AND CONVERTING SAID BENEFICIATED FRACTION TO SODA ASH BY CIRCULATION.

21 Apr 1971TL;DR: A process for the MANUFACTURE of SODIUM percabonate is described in this paper, with the main focus of the process being of a SUFFICIENTly High CONCENTRATION to insure the PRECIPITATION of at least part of the running time of the SODUM PERCARBONATE SLURRY.
Abstract: A PROCESS FOR THE MANUFACTURE OF SODIUM PERCABONATE COMPRISING THE STEPS OF MIXING AN AQUEOUS SOLUTION OF SODIUM CARBONATE WITH APPROXIMATELY THE STOICHIOMETRIC QUANTITY OF AN AQUEOUS SOLUTION OF HYDROEN PEROXIDE, SAID SOLUTIONS BEING OF A SUFFICIENTLY HIGH CONCENTRATION TO INSURE THE PRECIPITATION OF AT LEAST PART OF THE THEREBY PRODUCED SODIUM PERCARBONATE; VIGOROUSLY AGITATING, THE AQUEOUS SODIUM PERCARBONATE SLURRY SO PRODUCED, AND FEEDING SAID SLURRY TO A SPRAY DRYER IN AN ESSENTIALLY HOMOGENOUS STATE, THEREBY PRODUCING A DRY, FREE-FLOWING SODIUM PERCARBONATE PRODUCTo
