Show ANACONDA ZINC SUCCESS in reviewing recent metallurgical acco accomplishments in ments john D ryan president of the anaconda copper company of montana has the iol following lowing to say of his companas comp anys success in the manufacture of electrolytic zinc in many of the mining districts of the west particularly those which are producers of either silver lead or copper ores zinc in varying quantities forms an important and hitherto very objectionable constituent found usually in quantities insufficient to justify working the ores for the recovery of this metal its presence occasioned the metallurgist numerous difficulties in the endeavor to eliminate it while saving the valuable metals associated with it in the ore these difficulties compelled the smelters shelters sm elters to impose heavy penalties on the zinc content in excess of certain percentages the presence of such refractory ores in some of the mines of the anaconda company led to a careful study of the problem by its research department gratifying success has resulted from this study an electrolytic process has been evolved and patented to the company which makes it possible at a satisfactory cost to extract a high percentage of the zinc content of such ores while tile the other valuable metals are precipitated in the form of an easily reducible residue following experiments sufficiently long continued to demonstrate the success of the method a plant capable of producing pounds of electrolytic zinc per day was built at anaconda and has been in successful operation for several months the product is very pure its zinc content being about per cent the brand which has been trade marked anaconda electric finds ready sale at a considerable premium among manufacturers whose requirements demand zinc of the highest grade this operation has been so successful that the company is now enlarging the plant at anaconda sufficiently to make an output of pounds of zinc per day the product of this plant has been sold for a full year from the time when it will be in complete ope operation ration at an esti mated profit of over and construction has been started upon a plant at great falls capable of making an output of pounds of zinc per annum which we hope to have in operation in the early autumn of this year |
