The Philippines has 4.2 billion metric tons of copper reserves. Mined and processed, the copper ores may be converted into copper wire of various sizes which may become the major parts of electric motors of all sizes and capacities. Copper wire and parts likewise form major parts of power generators, transformers, power distribution equipment, electric and electronic gadgets, computers, battery chargers, etc. All such products may be made thru use of electric furnaces to melt copper concentrates, refine them thru electrolysis equipment, and draw out the resultant ingots into copper wire, or form the ingots (using molds and machine tools) into copper parts for various products. Alloyed with tin or zinc and other metals, copper forms various types of bronze or brass ingots which are raw material bases for thousands of product types. Development of Philippine hydroelectric and geothermal power resources as described in the previous topics will facilitate establishment of suc
