Ironically, Indonesia has been exporting Galena Ore and importing Lead (Plumbum) since there is no capability to process Galena ore economically. To process the Ore into 99.9% Lead, we need miller or pulverizer, chemically washing unit, smelter and a refinery, and neutralize the toxic sulphuric gas effluent .
Now the technology is available locally, cheaper and environmentally friendly since the toxic sulphuric gas is neutralized using cyclone technology.
