실험 절차

Australian Pat. No. 28,957, (1971) describes a method of precipitating lead chloride from brine solution by cooling followed by reacting said lead chloride with water and calcium sulphate to produce a lead sulphate precipitate and calcium chloride solution. Although low chloride levels in the lead sulphate were obtainable with rigorous washing, the product is again suitable to lead smelters in limited quantities and must be treated on a sinter machine to remove sulphur before the blast. Capital and operating costs are projected to be high for the process since the brine solution must be heated for high lead solubility and then cooled for lead chloride precipitation.
