PH's first eco-friendly mineral processing plant built by DOST, UPSaturday, March 11, 2017 05:11 AM Views : 166Martin Sadongdong
The Department of Science and Technology (DOST) and University of the Philippines (UP) collaborated to build the country's first integrated gold-copper mineral processing plant which does not use harmful chemicals.
DOST Secretary Fortunato de la Peña led on Friday (March 10) the inauguration and turnover of the UP-DOST Integrated Gold-Copper Mineral Processing Plant to its plant-beneficiary, the Benguet Federation of Small Scale Miners (BFSSM) in Sitio Basil, Barangay Gumatdang, Itogon, Benguet.
De la Peña said the P25-million Integrated Gold-Copper Mineral Processing Plant is an eco-friendly plant as it does not use the common chemicals used by large-scale mining plants in its extraction process.
"It uses clean technology developed by UP Diliman researchers and what's more important is, walang mercury and cyanide. The liquid effluent is clean, clear water. The solid residues are now going through R&D (research and development) as construction material," De la Pena told the Manila Bulletin on Saturday (March 11).
De la Peña said the technology uses an "enhanced gravity concentration-flotation-extraction" process which ensures that waste materials the plant will dispose are safe and non-pollutant.
Dr. Carlos Primo David, head of DOST- Philippine Council for Industry, Energy and Emerging Technology Research and Development (PCIEERD) that co-developed the technology, said the integrated gold-copper plant also has a built-in wastewater treatment system designed to recycle the water it uses in processing the mineral ores.
The integrated plant, David added, can also yield higher percentage of gold extraction from the mineral ores, affirming their commitment to support the country's small-scale industry.
