Show looses new mill said 0 to o be doing good work many utah mine operators are watching with interest the results of the milling experiment which senator reed smoot col C E loose and associates are conduct ing frig on an entirely new kind of ore in southern utah the ore is cop per carbonate impregnated through great flat beds of sandstone the following story from the moab times indicates that the new process may be a financial success no longer Is there any doubt as to the success ot of the big indian copper reduction process during the past week the mill has been running steadily and already nearly two tons of concentrates have been produced on tuesday night the plant was closed down for examination after 44 hours of continuous precipitation and everything was found to be in good shape and running perfectly the process for which the mill has been designed precipitates about 80 per cent of the copper in 14 the ore the remaining 20 per cent comes down as copper sulphate wych can not be by means of df steam this percentage of the cop per will be saved by means of scrap iron on which it will be perel ed later a simple and satisfactory process tor for precipitating the copper sulphate which has already been worked out will be installed preston G peterson secretary of the big indian copper company came down from the mill last night and reported that the mill was op aerating in a highly satisfactory man ner that the process is proving to I 1 be economical and a quick method of copper from the ore there is no longer any doubt he said and the results have more than justified the construction of the big mill the product from the mill at this time Is a concentrate running about 80 per cent in copper of which near ly two tons have already come through the towers later on this will be roasted and smelted and pure copper dopper bullion will be shipped out from the mill the actual operation of the ml I 1 has proven that a number of changes I 1 in handling the process will still have to be made before the best re suits can be obtained it is the in of the company Secre Se cretai taij peterson said to run continuously tor for about 40 days and produce p about two carloads of precipitate to prove beyond question the efficiency of the process after this la Is done the plant will be shut down for a month or so during which time the change in the design of the mill will be made nearly all of the employees of the company have asked for a lay off during the fourth of july and dur ing this period a few minor changes will be made in the mill about july milling operations will be resumed to continue for 40 days by tal fail or early winter it Is figur figu r ed that all the re designing of the big plant will be completed the ca lacity of the mill will thereby be en barged and actual permanent mill ing operations on a large scale will commence we feel that we have got over the top now said secretary peter son heretofore the only question I 1 about the enterprise was whether or not the new process which has been tested thoroughly in laboratories and found successful would work out on a large scale we know now that it will and all of the remaining work to be done Is only for the pur pose of bettering our methods of handling the process to the best ad vantage and to the end of increasing the output |
