2.2.3 Crane operation

The automated electrode handling crane equipped with one positioning lifting bale willbe used to perform the following main duties:Lift batches of deposited cathodes from two adjacent electrowinning cells and transferthem to the stripping area. Consecutively returning with stripped cathodeblanks to

deposit them in the spaces of the cells that were vacated by harvesting cathodes.This operation will be cyclical and fully automaticLift anodes from two adjacent cells for draining and cleaning. Periodic, semi-automatic operation with lifting bales.Pick up, install and remove jumper frame for cell maintenance in semi-automaticoperation mode.General maintenance duties including the removal and replacement of damagedcells. Occasional, manual operation with hooks of the auxiliary hoists and otherequipment as required.

Cathodes will be pulled from the two adjacent cells in groups of 40 for washing andstripping. Replacement stripped blanks, also in pre-spaced groups of 40, will be returnedby the tankhouse cranes for reinsertion into the electrowinning cells, before any additional

cathodes are pulled.

The automated electrode handling crane will perform the following operational sequenceswith no interruptions between any set of consecutive tasks:

Crane transfer from previous harvested cells to new cells to be harvestedCrane bale movement to pick up a specific third of cathodes in two adjacent cells

Hood lifting movement above two adjacent cellsOpen drip traysPicking up cathodes

Closing drip traysRelocate hoods

Crane drive to inlet CSM

Open drip traysDeposit of 40 cathodes to the inlet rack of the CSM.
