Waste batteries' processing and recycling

Many countries in Western Europe, not only in stores, but also directly in the street have recycling special box, the fee will be collected using specialized sieve battery selected those terms watches, calculators and other small electronic devices of the button batteries, they which generally contain mercury, can be extracted from the use of mercury, and then manually sorted out nickel-cadmium battery cell, France at a factory to extract the nickel and cadmium, nickel and then used in steelmaking, are re-used in the production of cadmium batteries . The rest of all types of dell laptop battery are generally devoted to the toxic and hazardous landfill site, which not only cost too much (for example: in Germany, a ton of landfill waste battery cost of 1700 marks), but also lead to waste of resources, which There are still a number of useful materials can be used for the material. Switzerland there are two specialized processing plants to use the old inspiron 6000 battery , and then sent to the furnace heating, can be extracted at this time of volatile mercury, zinc, when the temperature is also higher evaporation, It is also a precious metal. Iron and manganese after fusion of manganese ferroalloy steel requirements. Machinable year the plant 2000 tons of waste batteries, available 780 tons of manganese ferro-alloys, 400 tons of zinc alloy and three 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 for each inspiron 9300 battery to charge the purchase of a small number of dedicated processing waste battery charges, the State magdeburg peri-urban areas is the construction of a "wet" installation, where in addition to lead-acid batteries, the various types of cells are dissolved in sulfuric acid, and then through ion resin extracted from the solution of various metal objects, using materials obtained in this way heat treatment methods than pure, so a higher price in the market, and the battery contained in a variety of substances 95% can be extracted. Wet processing can be saved links sorted (because it is sorting manually, will increase the cost). Magdeburg annual processing capacity of this device up to 7500 tons, the cost is slightly higher than the landfill method, but do not throw away valuable materials will not pollute the environment. Germany Duarte developed vacuum heat treatment but also the cheapest method, but it first needs to be sorted out of batteries in nickel-cadmium inspiron 9400 battery, battery waste heat in a vacuum, in which the rapid evaporation of mercury can be recovered, and then the remaining material grinding, metallic iron extracted by mag .
