Abstract
A system is described for forming a recycled copper product from at least one copper scrap feedstock source containing at least one contaminant. A pre-determined maximum weight percentage of the contaminant in the recycled copper product is initially established. The weight percentage of the contaminant in the copper scrap feedstock source is then determined. A determination is then made as to whether the weight percentage of the contaminant in the copper scrap feedstock source will exceed the established maximum weight percentage of the contaminant in the recycled copper product. If so, another copper scrap feedstock source is then added to the first copper feedstock source so as to cause the combined copper scrap feedstock sources to have an average weight percentage of the contaminant that does not exceed the established maximum weight percentage of the contaminant in the recycled copper product.
