Study machine centrifugal extraction solvent extraction processing waste zinc manganese battery experiments is to choose the waste zinc-manganese batteries for processing samples, through research, water leaching and acid leaching conditions, obtain the best condition of acid leaching and zinc manganese ion of dilute solution, and the use of the extraction results of the simulation system for leaching liquid extraction performance research, the last of the zinc manganese zinc and potassium permanganate solution mixture separation.
the production of battery is 96% zinc manganese battery and alkaline manganese battery, its main components in manganese, mercury, zinc, chromium and other heavy metals. Waste battery in the atmosphere or buried deep in the ground, the heavy metal content with drainage overflow, cause the pollution of groundwater and soil, accumulate over a long period, will cause serious damage to human health. Machine centrifugal extraction solvent extraction processing waste zinc manganese battery is the mature technology of wet processing, dilute solution for metal recycling has high efficiency and high selectivity.
solvent extraction method to extract the constituent of waste zinc manganese battery has a price, and obtain ideal acidification and extraction conditions, and the obtained zinc manganese in manganese zinc mixture separation and preparing zinc chloride and potassium permanganate solution. Machine centrifugal extraction solvent extraction processing of waste in the process of zinc manganese battery, saponification extracting agent and improve the solution pH can increase the rate of extraction of zinc, manganese, in contrast to improve the effect of pH of solution is more apparent, especially for increasing extraction rate of manganese is more advantageous. Finally, mix the zinc manganese solution separation and solution with potassium permanganate and zinc. Source:
