Procedure

Accordingly, the process of the present invention comprises melting a mixture of finely divided a natural magnesium silicate and sodium carbonate, preferably, under slightly reducing conditions whereby a clear melt is obtained which upon quenching and dissolving with water provides a solution of sodium silicate and sodium hydroxide which is recovered after separation from the insoluble fraction comprising predominantly magnesium oxide.
