the basket into the compartments of basket 8 is placed the anode material of the invention in a particulate form such as small blocks or small slabs during operation of the cell the anode material is gradually consumed and is simply replaced by adding further particles of the anode material into the basket in an alternative form shown in fig3 the anode comprises a foraminate titanium basket 13 which is suspended by hooks 14 from a copper hanger bar 15 fig1 also shows the use of melded fibre structures in conjunction with the more open meshed metal or plastics material baskets 16 shows a basket having a melded fibre structure on the inside and 17 illustrates a basket having a melded fibre structure on the outside 18 refers to baskets having melded fibre structures on the inside and on the outside the use of titanium anode baskets has been previously disclosed in connection with electroplating of various articles but has not been considered possible for electrowinning applications clearly it would be useless to use pure copper in the basket in an electrowinning cell since the anode would simply dissolve completely leaving only the titanium basket which would rapidly passivate and the electrolysis would stop it has now been discovered that using the anode material of the invention in a titanium anode basket the current is able to pass.
