1. Postupak za kontinuiranu i elektrokemijsku proizvodnju olova visoke čistoće iz otapala za elektropreradu obogaćenog ionima olova u otapalu koje sadrži: tretiranje aktivnih olovnih materijala s bazom kako bi se dobila topiva sulfatna sol i aktivni olovni materijal obrađen s bazom koji uključuje olovne okside i olovne hidrokside: otapanje aktivnog materijala olova obrađen bazom u otapalo za elektropreradu da bi se na taj način oblikovalo otapalu za elektropreradu obogaćeno ionima, pri čemu je otapalo za elektropreradu alkan sulfonska kiselina i ne uključuje kelator: umanjuje ione olova u otapalo za elektropreradu obogaćenom ionima na katodi čime nastaju adhezivni slojevi olova visoke čistoće i regenerirano otapalo za elektropreradu, pri čemu mikro- ili nanoporozna miješana matrica i pri čemu olovo visoke čistoće ima čistoću od najmanje 98%; uklanjanje prianjajućeg olova visoke čistoće s jednim dijelom katode, dok se olovni ioni reduciraju na drugom dijelu katode, pri čemu se katoda pomiče u odnosu na otapalo za obradu elektrode obogaćene olovom tijekom koraka smanjenja iona olova; dodirivanjem barem dijela regeneriranog otapala za elektropreradu s olovnim materijalom koji sadrži rešetkasto olovo i aktivni olovni materijali da bi se tako dobio barem dio otapala za obradu elektrode obogaćene olovom.1. Process for the continuous and electrochemical production of high-purity lead from a solvent for electroprocessing enriched with lead ions in a solvent containing: treating active lead materials with a base to produce a soluble sulfate salt and base-treated active lead materials including lead oxides and lead hydroxides: dissolving the active base-treated lead material into an electroprocessing solvent to thereby form an ion-enriched electroprocessing solvent, wherein the electroprocessing solvent is an alkane sulfonic acid and does not include a chelator: reduces lead ions in an ion-enriched electroprocessing solvent at the cathode, resulting in adhesive layers of high-purity lead and regenerated electroprocessing solvent, wherein the micro- or nanoporous mixed matrix and wherein the high-purity lead has a purity of at least 98%; removing adhering high purity lead with one portion of the cathode while reducing lead ions at the other portion of the cathode, wherein the cathode is moved relative to the lead-enriched electrode treatment solvent during the lead ion reduction step; contacting at least a portion of the regenerated electroprocessing solvent with the lead material containing lattice lead and active lead materials to thereby obtain at least a portion of the lead-enriched electrode processing solvent. 2. Postupak sukladno patentnom zahtjevu nadalje sadrži korak oporavka baze iz topljive soli sulfata kao reciklirane baze i koristeći barem dio reciklirane baze za ekstrakciju sumpora iz aktivnih olovnih materijala.2. The process according to the patent claim further comprises the step of recovering the base from the soluble sulfate salt as the recycled base and using at least part of the recycled base to extract the sulfur from the active lead materials. 3. Postupak sukladno patentnom zahtjevu 1, pri čemu se adhezivno olovo visoke čistoće uklanja s površinskim sakupljačem na neljušteći način, i pri čemu je površinski sakupljač postavljena proksimalno na katodu.3. A method according to claim 1, wherein the high purity adhesive lead is removed with the surface collector in a non-peeling manner, and wherein the surface collector is placed proximal to the cathode. 4. Postupak sukladno patentnom zahtjevu 1, pri čemu adhezivno olovo visoke čistoće ima gustoću manju od 5 g/cm34. The process according to patent claim 1, wherein the high-purity adhesive lead has a density of less than 5 g/cm3 5. Postupak sukladno patentnom zahtjevu 1, pri čemu otapalo za elektropreradu sadrži alkan sulfonsku kiselinu u količini od 5 i 50 wt%.5. The method according to patent claim 1, wherein the solvent for electroprocessing contains alkane sulfonic acid in the amount of 5 and 50 wt%.
