How to get copper out of radiator?

Waste radiator is usually composed of copper, aluminum and iron. Due to the high price of copper, many people want to separate copper from radiator. But how to get copper out of radiator? Actually, there are many ways to separate copper from radiator, like physical treatment, chemical reagent treatment, crushing and separating by machine and so on. Maybe you don’t know much about these methods, then I will give a detailed introduction in this article.

1. Physical treatment

This way uses the principle of thermal expansion and contraction. Due to the copper and aluminum will expand when heated (shrink when cold), and the extent of their expansion (or contraction) is different. So just take advantage of this, heat them up first (not too hot, just put them in boiling water), or put them in the refrigerator to freeze, then copper will be separated from radiator. However, this way needs a huge amount water, and it takes a lot of time. The working efficiency is pretty low.

2. Chemical reagent treatment

This way will use hydrochloric acid. Hydrochloric acid is non-reactive with pure copper. Only immersing the radiator into the hydrochloric acid, the hydrochloric acid will dissolve the aluminum and iron on the radiator, and the copper will be left. However, if the radiator is immersed in the hydrochloric acid for a long time, the quality of copper will be affected. In addition, you need to be very careful when using hydrochloric acid, because hydrochloric acid is a highly corrosive chemical. Even more, using hydrochloric acid does harm to environment which doesn't conform the environment protection rules.

3. Crushing and separating by machine

The third way is to get copper out of radiator by copper aluminum radiator recycling machine. The whole process of copper aluminum radiator recycling machine includes shredding, crushing, negative-pressure baffling separation, magnetic separation and air separation. Through these steps, you can get high purity of copper, aluminum and iron. The separation rate can reach to 99%. And the whole process doesn't use water, fire, or chemicals, which will not pollute the environment.
