Waste Battery Recycling Technology

The following describes three kinds of waste dry Casio NP-100 battery recycling technology:

a. Artificial separation recycling technology

To classify the dry battery , Sony NP-FH100 in general , simplely cut a battery to be open, artificial leather isolated zinc, plastic cover, carbon rods and so on from battery, put the remnants of Mn02, water, a mixture of manganese stone anyone to return to brick kiln calcination, made of dehydrated Mn02, this method is simple, but the occupation of labor are not more cost-effective.

b. Pyro-recycling technology

Generally it is to classify battery,such as Panasonic CGR-S003,and make them broken, then send into the rotary kiln at 1100 ~ 1300 degrees Celsius of high temperatures, zinc and zinc chloride is oxidized to zinc oxide, and exhausted with the flue gas , recovery zinc oxide with cyclone, the remaining of cyclone ,two manganese oxide and manganese stones get into the water, residues, further recovery manganese and other substances.this method is easy, the average smelter is Needless to add equipment, so zinc from Kodak KLIC-7001 battery can be recycled .

c. Wet-recycling technology

According to zinc, manganese dioxide can be dissolved in acid in principle, when the waste dry batteries forCanon NB-2LH is classified andbroken, placed it in leaching tanks, and obtained zinc sulfate solution by adding dilute sulfuric acid (100 ~ 120g / L), the rule of law must be used electrolytic metal zinc,copper residues is separated by washing cap, carbon rods, obtained Mn02 from battereyby calcination of manganese the residues Mn02, water, stone . The methods divided roast a leaching method and direct leaching.

Compared with fire method to recyce battery,Kodak KLIC-7001 wet method less investment , low cost, factory speed, high-profit, technical flexibility and other advantages, butit can not guarantee full recovery of harmful ingredients.
