Small-scale gold miners in Paracale, Camarines Norte use amalgamation process to recover gold from mined ores. In the process, they dispose untreated wastewater to water bodies. In this study, wastewater from an active SSGM ball mill facility in the area was analyzed for physico-chemical parameters and heavy metal concentrations.
miners amalgamate the whole ore in small ball mills, the mercury loss can be as high as 15 parts of mercury per part of gold produced [5 ]. It has been reported that the whole-ore amalgamation process requires 10–25 g of mercury for the production of 1 g of gold while the concentrate amalgamation process requires only 1–3 g of mercury [ 6].
