three provinces that are most productive copper and gold producers in the philippines
Mines and Geosciences Bureau Region 13 (Philippines) In terms of potential for gold, Surigao del Norte still ranks high followed by Agusan del Sur and Agusan del Norte. For porphyry copper, rank is still the same although Agusan del Norte have a slight edge than Agusan del Sur as low-level diorite is already exposed in the Asiga area. At present, Surigao del Sur relatively ranks as lowest in potential for both epithermal gold and porphyry copper prospects among the provinces of the Region although its prospectivity may improve as exploration work progresses in the future.
Natural resources of India Copper has been used since ancient times. Details of copper mining and metallurgy are available in ancient works like Arthashastra. Copper is mainly used in industrial applications, electrical/electronic equipment and Consumer products such as utensils. Major resources of copper are available at Rajasthan, Madhya pradesh and Jharkhand. As of 2010, India had 1.56 billion tonnes of copper ore.[21] India is one of the 20 major copper producers. In 2008, India produced 7,10,000 tonnes of copper.[22] Hindustan Copper Limited, a public sector company, is the only producer of primary refined copper. Post-pillar method and blast hole stoping method are used for mining. Some of the domestic demand is met through scrap recycling. In India, copper scrap is recycled through direct melting, which is a hazardous process.[21]
