Abstract

Due to the world rapid depletion of mineral reserves, extraction of major elements (such as magnesium, potassium, sodium and etc. ) from Brines and bitterns has been a matter of discussion. Although Sea salts applications in diverse branches of arts and sciences, industrial and economic factors has been limiting their production. In recent work, we represented affordable extraction method for Magnesium Hydroxide using sodium hydroxide (NaOH) in experimental (1000 ml) and pilot (5000 L) scale studied. The laboratory research aimed to optimization critical parameters as washing time with mixed sea and fresh water, and excellent bittern density for the dosage adding NaOH. High grade and recovery can be attained in 15 min time consumption 5 ml NaOH (12/5 M), stripping rate 180 RPM, 5 level washing combining 2 liter fresh water mixing 9 liter sea water respectively, 99/7% and 46/87%. Washing process indicated classifier had unsatisfied the cycle results, but applying 3 similar polyethylene ponds Outcomes acquired very close to laboratory scale. Furthermore, pilot assessments emphasized that design of Salt work effluents for 7 days conditioning is urgent and unavoidable. Also, XRD analysis in conformity with increase concentration Kainite and schoenite during the certain time.
