MOHAVE COUNTY MINER; KINGMAN, ARIZONA, MARCH 30, 1912. The New Copper Process At Butte. A Butto dispatch says:--The elabor ate plant of the Copper Extraction Process Company, built at the Washoe smelter of the Anaconda Copper Min ing Company by A. C. Burrage and associates, for the application of the Bradley process in the extraction of copper, gold and silver from the slimes of the Washoe concentrator, is nearly ready for operation, though there have been some unexpected delays. There are over a million tons of these slimes piled up near the Washoe smelter, and the pile is constantly ad ded to although the Anaconda is itself treating some of the stuff by briquetting it as it comes from the concentrator and treating it in the blast furnaces. However, the furnaces cannot keep up with the output of the concentrator. The slimes carry about 1 1-4 per cent of copper and about a dollar in gold and silver per ton of slimes. By the Bradley process it is expected to recover practically all of the copper in the slimes. The Copper Extraction Process Com pany has a contract with the Anaconda Company by which it pays a stated sum per ton of slimes used. Another system of recovering the metals from the slimes, known as the Peck centri fugal process, is also being tested at the Washoe. , The Bradley plant has been built at a cost of over 25'),000$, and has a capac ity for treating over 250 tons of ma terial per 24 hours, with part of it capable of treating 500 tons per day. The process which is the invention of Charles S. Bradley, was developed 'in an experimental plant In Hayonne, N. J. The invention claims an econom ical method of dissolving the metals in copper ores by the use of a chloride compound as a carrier and transform er by which means waste products are made Insoluble and the metals taken in solution are removed from the gan gue and other constituents of the ore. from which solution they are after ward recovered. In the actual operation of the pro cess the ore containing a sulphide is subjected to a carefully conducted roasting operation in what is known as an amphldizer, in which operation the copper in the ore is roasted to a sulphate and most of the iron is con verted into ferric oxide. This step in volves heating the finely crushed ore in the amphldizer (which is a rotating moasting furnace) to a temperature of 450 to 550 degrees C, air being blown in theamphidizer to accelerate oxida lion. The roasted ore is thon brought into association with an excess, of cal cium chloride solution In a reaction drum which is maintained at a tem perature of about 100 degrees C Cupric chloride Is produced by the re action between copper sulphate and calcium-chloride, while any ferric sul phate in the ore coming from the am phldizer reacts with calcium-chloiide to produce ferric chloride, which is soluble. The calcium sulphate result ing from both these reactions is of course insoluble and is separated by Alteration in the succeeding step. The production of ferric chloride at the point is advantageous in that it dis solves any copper oxide, copper sul phide or metallic copper which was unaffected in the amphldizer, pro ducing copper chloride, and this ferric chloride also maintains the copper chloride in the cupric state. The patent specification states "any gold or silver present in the solution may be carried down during precipita tion of the iron, aluminum and copper and subsequently removed or separat ed therefrom, in any preferred man ner known to those skilled in this art." Gold and silver present in the ore is brought Into solution by making all the copper Into cupric chloride and then adding a small amount of chlor ine, chlorus or chloric compounds. The chlorides of silver and gold being soluble in calcium solutions, may after wards be precipitated with the cop per and subsequently separated. After leaving the reaction drum the mass of gangue, solutions and precipi tates is subjected to filtration. The solid matter forms a cake which con sists of the gangue In the oro except a small amount of Iron and alumina which have been taken into solution and tho calcium-sulphate precipitate already mentioned. The solution com prises a carrier in which have been dissolved the metals to be recovered, a small amount of iron and alumina and any zinc, which may have been in the ore; the arsenic will have been separated by dltration as it has been rendered insoluble. The solution is then subjected, if necessary, to a further oxidizing operation in order to be sure that the metals are all com bined at their highest valence. The solution is then in condition for treatment for separation of the metals dissolved. The prec'pitation of iron and alumina may be made by cupric oxide, hydrate or calcium carbonate, and as this precipitate will carry some copper, it is returned to the amphl dizer after having been removed from the solution by Alteration. In the am phid'zer the iron and alumina in the precipitate are rendered insoluble, while the copper is left iu a soluble condition and can be recovered. The solution from which the iron and alumina have been removed and which then contains the bulk of the copper is run to a second tank in which cop per is precipitated by carbonate of lime as oxide of copper. This precipi tate is filtered from the solution and the copper is recovered by further treatment such as by reduction in an ordinary smelting furnace. Zinc contained in the ore passes in to the solution as chloride of zinc and accumulates. It is therefore necessary at stated times to run the solution or part of it, after the final treatment and before returning it to the reaction drum, to a third precipitator in which the zinc is precipitated by means of burned lime. The regenerated solu tion from which Vhe gangue and all metallic compounds have been remov ed and which contain calcium chloride, is returned to the reaction drum for the treatment of additional ore from the amphidizer, thus completing the circle. "While the above description may indicate a rather complicated process the actual operation is comparatively simple and involves novel features and apparatus for the design and construe lion of which the Inventor and his as sociates deserve a great deal of credit," says Arthur L. Walker (The Engineering and Mining Journal), professor of metallurgy in Columbia Dniversity, in a recent article on the Bradley process. "By this process it is hoped to recover copper from material which cannot be satisfactorily treated in any other manner, and pos sibly to even make a greater extrac tion from certain ores than is now ac complished by other processes. In actual operation the regeneration of the carrier solution is so complete, there being practically no los. On account of this a considerable excess of calcium chloride solutions can be used and by means of this excess operators can bo conducted in a very "lastic manner and the exact balance required in the hydro-metallurgical process as heretofore tried is not absolutely necessary. The practically complete chloridizing of the metals takes place in a solution drum and not in a preliminary roasting process, and the reactions in this solution drum can be simply and easily retrulated. The results obtained by the plant in Ana conda will be awaited with a great deal of interest." The Portland Mill. It is predicted by Superintendent Thomas Crowe of the Portland mill at Cripple Creek that in March about 14,000 tons will be treated at the Victor mill. Many additions are being made from time to lime and new build ings are being erected at the mill, until now it covers the biggest portion of the east slope of Battle mountain. The slime tailings are being dumped into Eclipse gulch. There are 10 agitation tanks in the mill no"-. Less than a month ago a second tube mill was installed and the sixth Portland filter, made by the Colorado Iron Works, has been put in the mill. There are 31 concentrating tables, an increase of about eight since the first 300-ton unit was installed. A new Dorr thickener has been installed and a house built for it. In two months the mill will be just twice as large as the original plant and will have the capacity for treating twice as much ore. The sand tailings are dropped down an 800-foot stope and used for stope filing. The slime tailings are hauled in cars to Eclipse gulch and there dumped. The Portland metallurgists have successfully solved the problem of stacking the tailings, which has been one of tiie obstacles in local mill ing. Denver Mining Science. Gold Mines in California. A Jackson, Cal., The Lincoln Con solidated Mining company, at the re cent stockholders' meeting, decided to take over the famous Wildman-Mah-oney group of gold mines, in the Sutter Creek district. The Wildman-Mahoney has been developed to a depth of 1,400 feet, by the Wildman shaft, with two other shafts on the group. There are also three 40-stamp mills, which may be still used to advantage. The property has a credited productive record of about 3,200,000$ and for several years ranked among the greatest gold dis burses on the Mother Lode. Several companies have attempted to restore the property to its old time position, but lack of capital militated against success. When last worked an ore body 150 feet wide is said to have been exposed near the bottom of the shaft, with values exceeding 3$ per ton. The ore is free milling, yields readily to treatment, and is mined and milled at low costs. The Lincoln Consolidated people plan to open the property alobg vigorous lines and will increase the capital stock of the parent comopany to raise sufficient funds. At the Lincoln Consolidated the main 2,000 foot shaft has been un watered to the 1,950 foot point and irood ore opened on the 300 and 1,200 feet levels. Arrangements are under way to thoroughly develop the eastern portion of vthe property. It is probable the drift from the 1,200 foot level will be continued to tap the VViidman-Mahoney veins. It i aunounced the famous App mine, near Seulsbyville, is about to pass in to the hands of interests allied with the U. S Stnelting, Iiefining& Min ing company. Further rich discover ies have been recently made in the famous old producer, and the purchas ers are said to be highly pleased with conditions. Pennsylvania capitalists have acquired the old Pereira ranch, near Jamestown, and are arranging to prospect the property. The estate, comprising 160 acres, is traversed by a network of gold-bearing veins. As says of surface ore gives good values and the men from the Old Keystone State are confident of developing a valuable property. At the Eagle Shawmut50 stamps are in action and a heavy tonnage of good grade quartz is being handled The property con tinues to hold first place among Tuo lumne producers.
