Abstract

The recovering and utilizing method of waste alkaline zinc-manganese battery includes the following technological steps: 1. separating and extracting the positive pole and negative pole material; 2. soaking in alkali solution at room temperature; 3. separating zincate; 4. electrolysis to prepare zinc; 5. preparing potassium manganate; and 6. electrolysis to prepare potassium permanganate. The said technological process is simple and low in cost, produces few secondary pollution, and is favorable to reducing environmental pollution caused by waste battery.

Description

technical field [0001] The invention relates to the application fields of environmental protection and resource regeneration, in particular to a method for recycling waste alkaline zinc-manganese batteries. Background technique [0002] my country is a big producer and consumer of alkaline zinc-manganese batteries. Due to the low self-discharge rate, high capacity, and high power characteristics of alkaline zinc-manganese batteries, and because the country has formulated a low-mercury and mercury-free battery production policy, from January 1, 2005, domestically produced alkaline Zinc-manganese batteries have been completely mercury-free, and the production and consumption of alkaline zinc-manganese batteries occupy a dominant position in primary batteries. The mass production and use of alkaline zinc-manganese batteries has brought many problems to the society. Among them, environmental pollution and overexploitation of mineral resources are the ...
