Show POTASH PRODUCED FROM DUST As an example of what can be accomplished by the application of modern methods in effecting economy conserving resources and abating a nuisance it is a pleasure to call general attention to an innovation recently made by the portland cement company of utah at its plant in the southwestern portion of salt lake city where it is manufacturing potash from the dust generated in the production of cement buy utilizing dust such as formerly issued in big clouds from its plant and the expenditure pend iture of approximately 11 says the salt lake tribune the portland cement company of utah is augmenting its daily income to the extent of about and has gained a place on the list of potash producers of the united states I 1 the auxiliary plant for the production of potash as a byproduct by product of the cement industry is the first of the kind in the world and the process has been perfected and the plant erected in salt lake during the last seven months the trial run was made last monday and each day since an average production of about two tons of potash has been maintained the potash produced is in the form of a sulphate approximately 98 per cent pure a product not excelled and but seldom equalled equal led in the united states the price of potash fluctuates but seldom falls below a unit in these war times on this basis the product turned out by the portland cement company of utah is worth a ton representing an income of approximately a day from what formerly was a waste waste is eliminated under the new arrangement the clouds of obnoxious dust common to most cement plants and which represent a waste of from 2 to 2 21 per cent of the raw material are eliminated the dust is collected and the potash washed from iland it and crystallized crystal liz the other ingredients in the eustare du stare caught ana returned to the cement plant for utilization iza tion in the manufacture of cement prior to the opening of the world war the potash supply of the united states Was w obtained fron from L germany with the in terru tion of shipping four years ago the butash situation in this country was serious and ad the government and various industries began extensive experiments with a view to bringing about local production sufficient to meet the needs although it is now estimated 1 that approximately worth of potash is wasted annually in connection with the manufacture of cement no action was taken to obtain potash from this source until about two years ago the riverside portland cement company of california cal was the first to devise a successful process and erect a plant potash war need I 1 believing that it was the patriotic duty of every cement manufacturer in the country to aid in potash pro ducton and at the same time utilize a waste product the portland cement company of utah arranged with the riverside company to erect a plant in connection with the formers cement factory in salt lake the agreement was reached about seven months ago and F W T huber chief chemist and george A fisher general superintendent of the riverside company came to salt lake to erect the plant preliminary experiments on the part of the experts revealed that the raw mated mate rials used by the utah company were 0 usually high in potash and it was decided the new process to try out a new process than the ori original gilI effects a greater saving 1 to the treat process and is better adapted ment of the utah rock dust tests indicate indict effected that a per cent recovery is erected the planta plant the same men who 01 for working on a plant salt lake are tin Coni company panY opera portland cement ogden the in general prince near brigham city 10 feces are ne is similar but some changes thell corthell at the n nor because the raw materials 30 salt lake 1 plant are wet while those in compa com dry it is expected that the ogden within wi potash plant will I 1 be in operation next thirty days day s p |
