Definitions
- the invention relates to a system for silver refining according to the Möbius process for the processing of part-shaped raw silver, wherein in the anodes a raw silver receiving space and underneath an anode sludge receiving space with intermediate, anode sludge-permeable support for the raw silver fill are provided, as well as the support having at least two horizontally movable axis elements which extend essentially across the width of the support and between which a gap is provided for the passage of anode sludge.
- raw silver is anodically dissolved and cathodically deposited as female silver.
- plate-shaped silver anodes were originally surrounded by anode bags and arranged between stripping cathode sheets. The anode bags hold back the gold sludge - if an anode is used up, it is replaced, with the gold sludge from the anode bags after inverting the bags is unwound.
- anode body is a frame-like or basket-like structure made of insoluble metal, for example titanium, and is charged with raw silver granules, so that it can be driven continuously.
- a sieve plate is provided for separating raw silver debris from the anode sludge collecting chamber.
- the problem of blockage of the sieve bottom can also occur, even when the electrolyte is moving, since its gaps have to be narrow enough to allow only anode sludge to pass through.
- the raw silver granules remain solid for most of the silver dissolution period and that their size changes very little - the granules only soften when the silver content has dropped (from over 80%) to about 4%.
- the gold content is about 90%. It is believed that the palladium content is responsible for this resistance, the, timing has been enriched to about 6% for this.
- the granules almost disintegrate by themselves, but during the transition from softening to decay there is a so-called slush phase, in which sieve trays can become clogged.
- the support for the raw silver fill is provided in the form of at least two oppositely driven rollers with axes parallel to one another, the conveyor elements on the circumference of the roller, in particular axial conveyor ribs, for conveying anode sludge between the rollers and optionally between a roller and an adjacent stationary one Exhibit wall.
- the conveying elements fulfill the further very important function of bringing about the complete disintegration of the granules by movement - for this an oscillating movement of the rollers was preferred, where material can still remain in the roller gap while the conveyor elements are moving away after being conveyed from the conveyor elements to the roller gap. The same applies to the gap between the roller and the bottom container wall. It has now surprisingly been found that a disassembly effect of the granules which is even better than that of the A 896/97 by the applicant can be achieved if the conveying elements are not pivoted against one another but are moved back and forth in the axial direction
- the support ⁇ has at least two relatively movable conveyor elements with horizontal axes, which essentially extend over the width of the support and between which a gap is provided for the passage of anode sludge, especially as a result characterized in that the conveying elements are provided so as to be movable in the axial direction.
- the surfaces of the conveying elements touched by the granite are displaced with respect to the granary filling and ensure the necessary abrasion
- Preferred prismatic elements are straight prisms with a triangular cross section, which are arranged so that the gap lies between their edges, so that abrasion material is guided to the gap by slanting puddles.
- FIG. 1 is an end cross-sectional view
- FIG. 2 is a side cross-sectional view of one in one Electrode cloth between the stripping cathodes, which can be hooked into the basket anode with raw silver granite neck filling.
- FIG. 3 is an enlarged detail from FIG. 2
- the anode is a flat anode with granule receiving space 1 at the top and tapering at the bottom
- the granule receiving space 1 has a central, porous partition wall 4 and an anode contact plate 5 on each side.
- the anode basket can be flowed through with electrolyte, not shown, for this purpose perforated side walls and diaphragms are provided between the granules and the rare walls
- a mechanically driven granite separation device is provided between the granule receiving space 1 and the anode sludge collecting space, which extends under the granule bed essentially over its entire width, generally designated 6 and is described in more detail in FIG. 3
- the Granahenzerlegvor ⁇ chtung 6 has two straight prism poles 6A, 6B with a square cross-section, which run parallel to each other, the prism poles with their edges facing each other and against the side walls of the grana close-up space 1, which in their lowermost section 7A, 7B obliquely to the P ⁇ smenstetten hm thus there is a gap S1 between wall section 7A and prism bar 6A, a gap S2 between prism bar 6A and 6B and a gap S3 between prism bar 6B and wall section 7B, the gaps preferably having the same width.
- the gap width depends on the operating parameters of the system, including the size and composition of the raw silver granules - approx. 0.5 to approx.
- the P ⁇ smenstabe 6A, 6B are slidably held in supporting walls 8, which have relief holes 9 where the rod edges pass, so that solids can be removed laterally from the supporting walls 8 when the prismatic rods are moved parallel to each other
- a pivot lever 9 can be seen schematically, which engages the pin rods 6A 6B via a transmission axis 10 and cams 11 and - if it is pivoted back and forth - for one Disassembly of the granah remains in the three columns mentioned above ensures.
- the inclined sections 7A 7B and the shape of the prismatic rod 6A, 6B ensure the guidance of the granules to the gaps, so that there are no surfaces on which the granahen material could remain and there is no risk of clogging.
