A produced water stream in a GOSP is pretreated to remove total suspended solids, emulsified oil, total organic carbon, chemical organics and inorganics, and biodegradable matter. The pretreated produced water stream is further processed to remove hydrogen sulfide gas, which is split in an electrolysis cell to produce hydrogen, sulfur, and water. Following this, bromine gas is removed. The pretreated produced water stream, after the removal of hydrogen sulfide and bromine gas, is further treated using CO2 to produce several minerals. The pretreated produced water stream, after mineral production, is desalinated to produce fresh water and a reject stream. Several valuable chemicals are produced from the reject stream. This process recovers valuable minerals and chemicals from a produced water stream in a GOSP.
