Show IWHY BA6IISE IS good mm Murray Plant Discloses a Loss, but Kept Lawsuits to Minimum. EILERS GIVES DETAILS Figures Show How Minerals .Were Wasted Before System Sys-tem Was Installed. II Before tho eighth International Con-fi Con-fi gress of Applied Chemistry, Anton EII-1 EII-1 ers read a. paper on the baghousc system I of destructive fume elimination in smelt Ins. Among the plans described by him I was the Murray baghouso system of the I American Smelting &. Refining company, I which was installed at a cost or 4127,-I 4127,-I 134. and where 40."2 cotton bags were lull lu-ll stalled. During the period fioin July 7. I 1907. to February 29, 1012, the total B charge at tho smelter was 1.666.S57 tone, I containing 256.S70 ounces gold, !M,72fi.-I !M,72fi.-I 271 19 ounce silver. S54.953.15l pounds i lead and 16.521,715 pounds copper.

But If the Murray plant had happened hap-pened to be the one provided with Hs on ii arsenic establishment the cost of working up the fume would not havo, bepp over $5 per ton. thus diminishing the loss shown abovo by J34,C31. leaving the loss for four years and eight months still S21.101.2S, Why an Investment. I These llgures show that, taking the immediate financial outcome only, bag-houses bag-houses are not profitable In lwi smelting smelt-ing works, which treat ores low in the precious metals and especially in lead. Hut there Is another consideration to be taken into account when smelting works are, like Murray, situated near rannH and villages. Thlo Is the elimination of fonstant lawsuit?, which are bound to be, of frequent occurrence, when As203 and the sulphates of lead and other metals arc permitted to drop down Into the fields. It must be decided therefore in the case of each smelting plant whether It ts not good business to expend the monov for constructing and operating a baghousc though an immediate profit ie not appar- |
