Caiera Mining Company Solves Corrosion Problem With Lead Design and construction of Caiera Mining Company's Garfield, Utah, cobalt refinery five years ago offered a number of unusual and difficult problems which had to be worked out by Chemical Construction Corp.. which developed the process, and Caiera s parent company. Howe Sound Co. \ot the least of these was the design of the oxidation autoclave, a evlindrical pressure vessel 40 ft. long and 6 ft. in diameter which had to operate at 600 psi. in a temperature range of 400 to 450 deg. F. Originally of carbon steel con struction. internally clad with a 10 per cent type 316 stainless steel, it was coated with Epon paint, followed by glass cloth and asbestos paper, both applied with sodium silicate, and a final lining of one course of acidbrick. The oxidized solution slurry contained 30 per cent solids in the form of iron arsenate and calcium sulphate, and had the following ap proximate analysis: Cobalt Nickel Iron (ferrous) Iron (total) Copper Arsenic Ho 504 (free) Grams/Liter 60-75 2-3 5-7 10-12 2-4 2-1 100-250 Just two years ago the brick lining showed localized failure and exami nation. during repairs, revealed cor rosion of the stainless and deteriora tion of the other supplementary materials. As a result the vessel was completely refined using a 12-Lb sheet lead membrane, glass cloth and as bestos paper applied with sodium sili cate and one course of acid-brick. This was based on the knowledge that lead and lead wool in the environ ment had good corrosion resistance as long as it was not subject to abrasion, splashing or washing action. The lead was purchased in 9 ft. bv 25 ft. rolls, cut in lengths approxi mating one-half the vessel's circum ference and placed so that seams were staggered. All seams were burned and lead nozzle liners were installed and burned to the shell liner. During installation and burning, overhead lead sections were supported by a 3-4 in. plywood template, a segment of a cyclinder about 6 it. long, sup ported by cables passing through nozzle openings. The template was removed after the brick lining had been installed a course or so above the autoclave's horizontal center line. "Tell-tale" weep holes were pro vided in the shell to give warning of leakage but recent examination of one of the nozzles showed the lead liner to be in excellent condition with a good oxide or sulphate coating and apparentlv original thickness. Linings of this type -- a lead mem brane with acid-brick to protect the lead from abrasion or erosion and to insulate it against high or fluctuating temperatures -- ha\e given excellent performance in manv similar installa tions. Lead acid-brick construction is ideally suited to such use in both new and repair-tvpe construction. NEW 1.1 \1> !U II DIN*. < OY'TKl ( TH IN lit l.l.KTIN !"(.

One of the important advantages of lead in porcelain enamels is the in creased resistance to chipping it im parts to the enamel. As a result it can be punched or drilled, sheared or sawed with little or no chipping. The lead also imparts greater smoothness and brilliance as well as improving the enamel s elasticity and increasing its chemical resistance. Also, the addi tion of lead to porcelain enamel com positions materially reduces the firing temperature at which the enamel can be applied to the base metal.

L JA26128 THE Greater New Orleans Bridge. spanning the Mississippi River at New Orleans, with a center span of 1.575 ft., will be the longest cantile\er-tvpe span in the Lnited States when completed in 1958. The cantiie\er structure, including an anchor arm of 853 ft. on the New Orleans side and one of 591 ft. on the west hank, will be 3.019 ft. long. Elevated approaches will add another 7.700 ft. bringing the over-all length of the bridge to over 10.700 ft. Designed and engineered bv Modjeski & Masters, of Harrisburg. Penna.. the bridge is being built for the Mississippi River Bridge Author11 v. The cantilever structure will be :-upported on four reinforced concrete pirrs. three on huge caissons which ha\e been sunk deep into the ground to a safe supporting stratum of earth. and the fourth supported on piles. Structurally the bridge will be flanked on each side bv deck truss spans supported on concrete piers, and these deck truss spans in turn will be fol lowed bv a trestle-tvpe construction consisting of steel towers and bents on jiile supported pedestals. The ap proaches will descend on easy 3V; per cent grades to the highway and street connections at either end of the bridge. The bridge roadway between curbs will be 52 ft. wide, proriding initially two 12-foot lanes for traffic in each direction and if traffic warrants it. a fifth lane can be established for re versible traffic flow. The bridge superstructure and ap proaches are under construction by Bethlehem Steel Co.. Bethlehem. Penna.. and will involve more than 33.000 tons of fabricated structural steel requiring more than 18.000 gal lons of paint for the primer and in termediate coats. As is current practice on almost all of the highway bridges of the Lnited States, red lead based paints will be used for the primer and intermediate coats on the steel work of the Greater New Orleans Bridge. The paints were specified bv the consulting engineers. Modjeski & Masters, and the formula tions accompany the text. Red lead paints have long proved effective in protecting steel work against corrosion under particularly rugged atmospheric conditions, such as high humidity coupled with high industrial activity, the same type of corrosive conditions that can be ex pected to surround the Greater New Orleans Bridge.
