| Summary: | The study on the leaching of heavy metals from rock and sediments, consist of quartz veins, altered wall rocks, volcanic rocks, soil and lateritic soil. The mineralogical study of the sulfide minerals using microscope and Electron Probe Micro- Analyzer (EPMA) indicates that the sulfide minerals contain high quartz veins, medium altered wall rocks and low volcanic rocks. The sulfide minerals have pyrite, pyrrhotite and chalcopyrite, and heavy metals appear to be Cu Zn As Ag Cd Au Hg and Pb. According to Synthetic Precipitation Leaching Procedure (SPLP) method at pH 4 to simulate the worst case scenario using Inductively Coupled Plasma Mass Spectrometry (ICP-MS), the results indicated that Hg were leached out exceeding the Industrial Effluent Standards and the Surface Water Quality Standards in all rock type. Cu can leach out exceeding the Surface Water Quality Standards in altered wall rocks. However sulfide minerals be found in Khao Phanom Pha Gold Mine are less than other gold mines. And the quantity of quartz veins and altered wall rocks in this gold mine is a little less than volcanic rocks. These result lead to management and monitoring plan for reducing the environmental problem causing in future. |
