PROCESSING METHOD FOR ROCK INCLUDING HEAVY METAL OR THE LIKE

To provide a processing method for rock including heavy metals or the like capable of restraining dispersion of heavy metals or the like into atmosphere without needing re-blending coarse and fine grain rocks once separated.SOLUTION: A processing method for rocks including heavy metals or the like comprises classifying the rock into coarse grain rock and fine grain one, blending the fine grain rock with an insolubilization material and filling that material-including fine grain rock and the coarse grain rock so as to alternately layer. Since the material does not predetermine that the rock or the above material is totally uniform, the filling work, for example, and new generation of the heavy metals-including rock can be performed in parallel and further, the rock derived from other places can be received.SELECTED DRAWING: Figure 1 【課題】重金属等含有岩石の処理方法であって、一旦分離した粗粒岩石と細粒岩石とを再混合する必要がなく、重金属等の環境中への拡散を抑制することができる処理方法を提供する。【解決手段】重金属等を含有する岩石を粗粒岩石と細粒岩石とに分級し、細粒岩石と不溶化材とを混合し、不溶化材を混合した細粒岩石と、粗粒岩石とを交互に層状になるように盛土する。この処理方法は、全体としては岩石や不溶化材が均一であることを予定していないので、例えば盛土を重金属等含有岩石の新たな発生と並行して行うこともできるし、他所由来の岩石を受け入れることもできる。【選択図】図１
