摘要： The present publication describes a process for the preparation of lignosulfonate-based mixtures used in particular as additives of concrete. According to the process of the present invention, the sulfite spent liquor is treated with a nitrating reagent, such as nitric acid or nitrogen dioxide, and the reacted lignosulfonate is separated from the reaction product, and, together with the reacted lignosulfonate, the nitrate and nitrite compounds are separated from the reaction product, and the product mixture formed by the reacted lignosulfonate, nitrate compounds and nitrite compounds is purified in a way known per se. The product prepared in accordance with the process is suitable in particular for the liquefaction of concrete, for accelerating the setting of concrete, and for inhibiting corrosion of concrete reinforcement steels contained in concrete, if any.

摘要： A process for the recovery of lead from battery scraps by mixing the lead raps at elevated temperature with an aqueous solution of an alkali metal chloride and hydrochloric acid in order to dissolve, in the form of lead chloride, the lead compounds present in the lead scraps, separating an aqueous solution of this lead chloride from insoluble hard lead, which is recovered, crystallizing lead chloride from the cooling aqueous solution, which is separated from the lead chloride crystals, and finally subjecting the obtained lead chloride to electrolysis for the recovery of metallic lead.
