Stosowana dotychczas metoda polega¬ la na tym, ze zageszczony osad z filtrów Mo- ore'a po dokladnym zmieszaniu z woda w sto¬ sunku 1:0,6 byl traktowany kwasem siarkowym i kierowany na filtry OHvera.Szlam z filtrów Moore'a zawiera duze ilosci cynku w postaci okludowanego roztworu ZnSC4. Przez dodawanie kwasu siarkowego wzrastala zawartosc okludowanego Z11SO4, co powodowalo zwiekszenie mazistosci szlamu i utrudnialo znacznie filtracje na filtrach Oliye- ra.

Prze¬ mywanie szlamu za pomoca dysz zraszajacych bezposrednio na filtrach Oliyera nie zdalo egzaminu, gdyz powiekszalo jeszcze jego ma- zistosc i zmniejszalo szybkosc filtracji.Sposób wedlug wynalazku polega na zawra¬ caniu szlamów po wylugowaniu na filtrach Moore'a ponownie na wydzielone filtry Moore'a w celu ich zageszczenia oraz przemycia dosta¬ teczna iloscia wody. Dzieki temu odzyskuje sie rozpuszczalne zwiazki cynku i kadmu w posta¬ ci wodnego roztworu, który poddawany jest zageszczaniu na odparowalnikach. Zageszczony osad pozostaly po przemyciu na filtrach Mo- ore'a przerabia sie w znany sposób na filtrach Oliyera. Przygotowany w ten sposób szlam przyspiesza znacznie filtracje na filtrach Oli¬ yera. Zwiekszono tym samym przepustowosc tych agregatów a odpadowy szlam z filtrów Oliyera jest dobrze obsuszony i zawiera mniej wilgoci. PLOF THE REPUBLIC OF PEOPLE PATENT DESCRIPTION No. 39624 KI. 40 c, "H Zaklady Zynkowe" Szopienice46 *) Przedsiebiorstwo Panstwowe Szopienice, Poland A \ Q & Method of increasing the leaching yield in the process of zinc electrolysis The patent lasts from February 7, 1956. In zinc electrolysis plants, sludge from Dorra settlers is thickened in a known manner, then after leaching, they are directed to the 01ivera filters.The method used so far was that the concentrated sediment from Moore's filters, after thorough mixing with water in a ratio of 1: 0.6, was treated with sulfuric acid and directed to the filters OHver. The sludge from Moore's filters contains large amounts of zinc in the form of an occluded ZnSC4 solution. By adding sulfuric acid, the content of occluded Z11SO4 increased, which caused an increase in the smeariness of the sludge and significantly hindered filtration on Oliyera filters. Due to poor filtration on 01ivera filters of these aggregates was insufficient, and the sludge from the 01ivera filters contained large- *) The proprietor of the patent stated that the inventors of the invention are Eng. ieczyslaw Kapczynski, engineer Włodzimierz Wozniczko, engineer Henryk Lakomski, engineer Eugeniusz Kubacki, MA Jan Nosal and Konrad Halota. with parts with a high zinc content. Washing the sludge with spray nozzles directly on the Oliyer filters did not work, as it increased its thinness and reduced the filtration rate. The method according to the invention consists in recycling the sludge after leaching on the Moore filters back to the separated Moore filters' and in order to concentrate them and to wash them with sufficient water. As a result, the soluble compounds of zinc and cadmium are recovered in the form of an aqueous solution, which is concentrated on evaporators. The concentrated sediment remaining after washing through the Moore filters is processed in the usual manner on Oliyer filters. The sludge prepared in this way significantly accelerates the filtration on the Oleyler filters. Thus, the capacity of these aggregates has been increased and the waste sludge from Oliyer filters is well dried and contains less moisture. PL
