Abstract

The brine solution remaining after salt crystallization contains high levels of valuable minerals, particularly magnesium, which can be extracted and processed into magnesium chloride (MgCl₂), a compound widely used in various industrial applications. This study examines the effect of hydrochloric acid (HCl) concentration and calcination temperature on the yield of MgCl₂ synthesized from brine-derived magnesium hydroxide. Magnesium hydroxide was precipitated using sodium hydroxide and subsequently reacted with HCl solutions of varying concentrations (1N–5N) before being calcined at temperatures ranging from 350°C to 550°C. The results show that both HCl concentration and calcination temperature significantly influence the product yield. The highest yield, 80.07%, was obtained at an HCl concentration of 4N and a calcination temperature of 550°C. While increasing acid concentration and temperature generally improved yield, concentrations above 4N did not provide further benefits and instead tended to decrease efficiency. These findings highlight key processing parameters for optimizing MgCl₂ production from brine, contributing to more efficient resource utilization and environmentally sustainable mineral processing practices.

Abstract

Barium sulfate crystals are minerals responsible for scaling in piping systems. Controlling the growth of these crystals can use additives (FeCl2 and SrCl2) and varying agitation speeds. The research was to optimize the impact of additives and agitation speed on the results of crystal form using RSM through Minitab 19 with Box-Behnken Design. The optimum conditions using additive FeCl2 at a concentration of 25 ppm, a stirring speed of 120 rpm for 30 minutes, and a coefficient of determination (R2) of 90.995 provided 0.4485 gr of barium sulfate crystals. The optimum conditions, however, used SrCl2 additives at a concentration of 20.2049 ppm and a stirring speed of 459.394 rpm for 30 minutes, yielding 0.4345 g of barium sulfates with a coefficient of determination (R2) of 91.41%. The results of crystallizing barium sulfate without additives appear to be superior to those obtained with additives in terms of production. In contrast, additives of FeCl2 and SrCl2 can inhibit barium sulfate formation, resulting in a reduction in crystal mass
