Abstract

The cathode comprises a stainless steel hanger bar 11 having a flat undersurface 12 with end portions 13 adapted to rest upon supports and electrical contacts, a flat stainless steel starter sheet 14 welded by its upper edge to the undersurface 12 between the end portions 13 so as to extend perpendicularly from said undersurface, the bar 12 and at least the marginal upper portion of the sheet 14 by which it is welded to the under-surface 12 of the bar being clad (e.g. plated) with copper as represented by the stippling. At least the upright side edges of the sheet 14 carrying masking 18. <IMAGE>

Description

Изобретение относитс к катодам дл электролитического рафинировани меди в водных электролитах.This invention relates to cathodes for the electrolytic refining of copper in aqueous electrolytes.

Цель изобретени - обеспечение возможности повторного использовани катода.The purpose of the invention is to provide reusable cathode.

На фиг.1 изображен предлагаемый катод, вид спереди; на фиг, 2 - то же, вид сбоку; на фиг. 3 - узел I на фиг, 2; на фиг, 4 - разрез А-А на фиг, 1 ,Figure 1 shows the proposed cathode, front view; FIG. 2 is the same side view; in fig. 3 - node I in FIG. 2; FIG. 4 is a section A-A in FIG. 1,

Катод содержит штангу I, выполненную в виде двутавра из нержавеющей стали, матричный лист 2 с отверсти - ми 3 дл подъема катода, защитное покрытие 4 боковых кромок матричного листа, выполненное из органического материала в виде жгута с пазом. На боковых вертикальных кромках листа и в жгуте выполнены отверсти 5, крепление листа к жгуту выполнено на шпильках 6, проход щих сквозь эти отверсти . Граница соприкосновени паза жгута с матричным листом уплотнена восковым .покрытием. Матричный лист прикреплен к штанге, перпендикул рно ее нижней поверхности сваркой 7, а штанга и прилегающа к ней верхн часть листа покрыты гальванически медью.The cathode contains a bar I, made in the form of an I-beam made of stainless steel, a matrix sheet 2 with holes 3 for lifting the cathode, a protective coating 4 on the side edges of the matrix sheet, made of organic material in the form of a rope with a groove. Holes 5 are made on the side vertical edges of the sheet and in the bundle; the sheet is fixed to the bundle on the studs 6 that pass through these holes. The boundary of the groove of the harness with the matrix sheet is sealed with a wax coating. The matrix sheet is attached to the rod, perpendicular to its lower surface by welding 7, and the rod and the upper part of the sheet adjacent to it are galvanically coated with copper.

Снар женный указанным образом катод завешиваетс в электролизную ванну с электролитом и в течение определенного времени на нем производитс осаждение меди. По достижении оптимальной толщины катодного осадка катод извлекаетс из ванны, и осадок с него снимаетс . Затем катод вновь завешиваетс в ванну дл следующего цикла.The cathode, charged in this way, is hung in an electrolysis cell with electrolyte and copper is deposited on it for a certain period of time. Upon reaching the optimum thickness of the cathode sediment, the cathode is removed from the bath and the sediment is removed from it. The cathode is then re-hung in the bath for the next cycle.
