Abstract

Mercury waste pollution is an environmental health issue resulting from poor management of mineral production waste materials. Small-scale gold mining areas using amalgamation techniques still contribute high levels of mercury waste to the environment. The technical issue of inadequate storage of production waste materials warrants adaptive control studies for small-scale gold miners (PESK). The aim of this research is to determine the efficiency of chemical and biological mercury waste control in small-scale gold mining cases. This research is a literature review using the systematic review method. The obtained articles underwent review, analysis, and comparison of the systematic capabilities of chemical and biological control. The results of this research found 11 relevant study articles published between 2017-2024. Chemical and biological control methods are capable of reducing mercury levels in tailing water by up to 99%. The form of adaptive control for small-scale gold mining conditions is assessed pragmatically and based on reduced mercury levels. The conclusion of this research is that applied research on mercury waste pollution cases in small-scale mining is still relatively lacking. Efficiency in controlling mercury levels is more realistic using biological control. Laboratory test result approaches can indicate the potential of biological control with bioremediation techniques as an efficient adaptive control effort for small-scale gold miners.

Abstract

This paper aims to characterize and test the stability of sulfuric natural water (SNW) from Sebau East Lombok as a sulfidation agent for several dissolved metals (Mn, Cu, Pb and Fe). The parameters used for SNW characterization are temperature, pH, DO, BOD, COD, TSS, and TDS. The sample was divided into two categories, namely the sample with preservation treatment and the sample without preservation, to study the stability of SNW. The SNW stability was determined by observing the SNW parameters in both samples at a storage time of 5, 10, 15 and 20 days and reacting them with dissolved metals. The SNW with preservation had reduced sulphide levels from day 1 to day 20, ranging from 59.24 mg/L to 17.70 mg/L, whereas the sample without preservation had decreased sulphide concentration from 52.46 mg/L to 9.56 mg/L. Furthermore, the SNW with preservation has a relatively superior metal reduction ratio than the sample without preservation. The maximum value of the deposition ratio for Mn metal was obtained on the fifth day with 57.60%, 83.45% for Cu, and 91.87% for Pb. This trend is not applicable for Fe, whereas the highest reduction (87.23%) was obtained on the the15th day's storage.
