5-4 The Experimental Investigation of Preparing Zinc Powders from Hot-dip Galvanizing Zinc Dross
With the facts that the hot-dip galvanizing industry continues to develop, the hot-dip galvanizing drosss output increases unceasingly and the zinc resources reduces constantly, the problem of the hot-dip galvanizing dross regenerative recovery has became the focus of the industrial circle, Therefore, this paper put forward the concept that using hot-dip galvanizing dross to prepare zinc powders directly from the reclaim and recycle of the zinc resource; And prepared zinc powder at the ordinary pressure according to the physicochemical characteristics of zinc that the vapor pressure of hot-dip galvanizing will change exponential near the melting point; and observed its exterior pattern, analyzed the distribution of grain size and determined the content of zinc
