Theoretical and experimental study of micronized dolomite dissolution

Abstract

Based on corrosion control and health requirement considerations, there is universal agreement on the need to remineralize desalinated water with calcium ions. Growing voices calling for supplementary addition of magnesium ions from health considerations have led to increasing searches of viable magnesium remineralization processes. Dolomite remineralization has a marked advantage because this mineral is a double salt composed of CaCO 3 and MgCO 3 , and its dissolution can provide both calcium and magnesium ions in a single process. The objective of this work was to enable application of the newly developed process of remineralization of desalinated water by micronized calcite powder dissolution to remineralization by micronized dolomite dissolution. Design models were developed and experimentally verified.
