BOUSSINGAULTITE PRODUCTION PROCESS FROM LIQUID EFFLUENTS CONTAINING MAGNESIUM SULPHATE

摘要

2 The process of producing magnesium sulfate and hydrated ammonium salt, MgSO4 (NH4) 2SO4, 6H2O (boussingaultita), is characterized by:(a) Preparation of synthetic solution of magnesium sulfate or liquid effluent using magnesium sulfate;(b) Addiction to a solution of hydrogen sulfide in the range from (a) to pH, ranging from 3.0 to 4.0;(c) Add 4.0 to 6.0 ammonium hydroxide or ammonia to the reaction medium between (b) and pH value;(d) Repeat stages (b) and (c) in sequence until the number of reagents consumed to prepare a successful agent;E) CRYSTALLIZATION OF THE SOLID THROUGH EVAPORATION OF THE WATER FROM THE REACTION MEDIA THROUGH HEATING TO A TEMPERATURE OF 80 ± 5 ° C AND FILTRATION FOR SOLID ISOLATION.
