How to deal with waste batteries?
In addition to lead-acid batteries, all kinds of batteries are dissolved in sulfuric acid, and then by means of ion resin from the solution to extract a variety of metals, raw materials obtained in this way than the heat treatment method is pure, so the market price is higher, and the battery contains 95% of the various substances can be extracted.
The old battery is ground and then sent to the furnace for heating, then the volatile mercury can be extracted, the temperature is higher when the zinc is also evaporated, it is also precious metals. Iron and manganese fusion after the steel to become the required ferromanganese alloy.
The rest of the various types of waste batteries are generally shipped to a special toxic, hazardous landfill, but this approach not only cost too much but also cause waste, because there are many useful raw materials available.
Laboratory recycling method: ordinary dry battery is cylindrical, the outer cylinder made of zinc, the zinc cylinder is the battery negative; tube central carbon rod for the positive; tube for the manganese dioxide, ammonium chloride and chlorination Zinc.
