Title: Study on Extraction Process of Potassium Salt Magnesium Sulfate Subtype Saline Lake Low Potassium
Abstract: The West Taijnar Saline Lake old brine pool of low potassium and high sulfur carnallite mixed salt as raw material,and potassium sulfate magnesium fertilizer discharged production workshop liquor and saline bischofite,by halogen process-the first positive flotation extraction of potassium chloride-reverse flotation process after the extraction of low sodium carnallite mixed salts,and the carnallite mixed salt particle size,liquor amount,decomposition time,direct reverse flotation reagent were main factors influencing relationship of experiments,to verify the feasibility of the process and obtain the best experimental conditions; process at the same time,by reverse flotation extraction of magnesium potassium sulfate fertilizer after flotation of extracting potassium chloride,verify its feasibility and potassium recovery test rate.Utilization of resource recovery increased sulfate type Saline Lake low potassium and high sulfur carnallite mixed salt mine,provided a new method for the total recovery of potassium and magnesium production system,reduced the rate of production cost.
