Recycling used batteries in three forms

Internationally accepted methods used batteries generally have three types of treatment: Curing buried, deposited in the mine waste, recycling. 1. Curing buried, deposited in the mine waste Such as a factory on the French to extract nickel and cadmium, nickel and then used in steelmaking, are re-used in the production of cadmium hp f2024b , hp f2024a . The remaining types of batteries are generally transported to specific toxic and hazardous landfill site, but this practice is not only too expensive but also wasteful, because there are still one of many raw materials can be used for a useful material. 2. Recycling (1) heat treatment Switzerland has two specialized processing make use of the old battery factory, the company approach is the old battery ground and rushed to the furnace heating, then extracted volatilized mercury, temperature is also higher zinc evaporation, it precious metals are same. Iron and manganese after fusion required for manganese ferroalloy steel. The Factory Machinable year 2000 tons of waste omnibook xe3 battery,hp 346970-001, available 780 tons of manganese ferro-alloys, 400 tons of zinc alloy and 3 tons of mercury. Another factory is extracted directly from the battery of iron and manganese oxide, zinc oxide, copper oxide and nickel oxide and other metal compounds as the direct sale of scrap metal. However, the higher cost of heat treatment methods, Switzerland also provides batteries to each buy a small amount of scrap batteries to charge special fees processing. (2) "wet processing" Magdeburg peri-urban areas is the construction of a "wet processing" devices, where in addition to lead-acid hp hstnn-db02 , hp hstnn-ub02, the various types of batteries are dissolved in sulfuric acid, then with ion resin extracted from the solution of various metals, using raw materials obtained in this way than pure heat treatment method, so a higher price in the market, and the battery contained in a variety of substances can have 95% extracted. Wet treatment may be omitted aspect sorting (sorting is because manually, will increase the cost). Magdeburg annual processing capacity of this device can reach 7500 tons, although its cost is slightly higher than the landfill method, but the precious raw material is not discarded, it would not pollute the environment. (3) Vacuum Heat Treatment Act Germany Duarte developed vacuum heat treatment method also cheaper, but it is necessary first of all spent batteries at sorting out the nickel-cadmium batteries, used batteries in a vacuum heating, one of the rapid evaporation of mercury can be recovered, then the remaining material grinding, extraction of metallic iron with magnets, and then extract the powder from the remaining nickel and manganese. This processing one ton of scrap hp dp390a , hp pp2100 , presario r3000 battery cost less than 1500 marks.
