Show POTASH IN LAKE OF WESTERN UTAH potash in surprising larget large proportions is 13 present in the brines and of the salduro marsh a sink in the salt lake desert about 60 miles west of ol 01 the southwest edge of great salt lake from the clays anderl underlying Y the salt body which covers the marsh the U S geology Geologic cal a i survey collected samples at depths of 8 to 12 feet in which the dissolved salts were found to contain from 2 to about 31 3 per cent of potash and per cent was found in the soluble salts at a depth of about 4 feet of the dissolved salts contained in the lines brines the salt crystals in the crust overlying these 3 to 4 per cent was found to be potash singularly enough the salt crust left at the surface e of the desert through the evaporation of the brines contains little more than ithan a trace of potash most of the potash being confined to the brines and to the underlying 1 der lying the salt crust the successful extraction of this potash is a fascinating as well as most pressing problem for the chemical engineer according to analyses made by the survey the brines and i from the salduro marsh contain considerable magnesium chloride as well as chlorides of potassium and sodium and so are somewhat similar in composition to the deposits from which potash is manufactured in germany therefore it appears that success in in methods for manufacturing potash at the salduro marsh should prove comparatively easy while no exten extensive give exploratory work has been done by the survey to show the area of the deposit it is believed that the amount of potash present in the region if it carf can be ext extracted with commercial success is is suf I 1 to pro provide iride a valuable source of supply to the country |
