Show A CHING New Mew Process For Por Treating Ores Announced University of California Aug A new process for lor treating rebellious ores ore and extracting their gold and sit sitTee stir Tee ver has been discovered by M Va gouny an assistant in the chemistry department of the University of Cali Should tIde this process proceso prove o ft commercial and practical success it means a saving of millions to the mining industry Mr says nays his process will be specially valuable in the exploitation of silver mines Like cyaniding said Mr this is in essentially a wet process A Astock Astock stock solution is made up as follows Some per cent erric chloride of commerce about 20 per cent com common common mon salt and per cent hydro hydrochloric acid This solution is made to pass through electrolytic cells with carbon electrodes where it is charged with chlorine under the influence of the current The solution is then contin continuously led over into ore vats ats contain containing containIng ing crushed ore and there it is given givena a chance to act upon the slIver silver and gold dissolve the latter and thus remove the valuables from the mass of ore by simple loathing leaching or ill fil filtration This rich solution is pow now made to flow through electrolytic vats again where not net only are the silver and gold readily realy obtained in the me metallic metallic condition on the cathodes but the solution itself is made to become richer with simultaneous regeneration of the ferric fattic chloride The solution now being ready to do more dissolving iC iCIs is again led into the ore vats leached and resent over Into the theore theore ore vats and so on cycle after cycle |
