An apparatus for determination of the portion of pure metal in dross from a dross source, whereby the metal portion in the dross is determined by measuring the dross density and calculating the metal portion in accordance with the formula m% =k·ρ+a, wherein m% is percentage pure metal, p is dross density and k and a are empirical constants. The apparatus includes a closed container configured to supply and remove gas, and for reading the temperature and amount of gas supplied to the container. |
