A STUDY ON ENVIRONMENT PROBLEMS IN PUBLIC GOLD PROCESSING IN THE AREA OF WONOGIRI DISTRICT
Abstract
The gold processing, which aim is to get the gold metal bounded in its gold containing
rock, is the important process after the mining process. The potential of gold mining
reserve in the research area has been proven as the gold mineral resources bounded in
andesite rock. The manufacture of gold ore in this research location uses amalgam
method which is in its local term called gelundung (amalgamator). The aim of this
research is to identify the environmental problems around the amalgamator
neighborhood. The research method which is used is descriptive observation method
around amalgamator environment. In addition, the research area is a steep mountainous
area. The finding of the research shows that the rocks resulted from the mine are crushed
with hammer then put in the amalgamator then mixed with mercury and some kinds of
leaves around the amalgamator. Afterwards, the results are tailing and amalgam. For the
amalgam (the compound of mercury and gold), it is burned so that the mercury
evaporates and resulted gold which ready to be sold. The environmental problems that
happen are the work safety aspect during the amalgam process, tailing pollution, and
liquid waste pollution which is directly poured to the ground.
