PHILIPPINE ZINC CONCENTRATE PRODUCTION
Zinc is a lustrous bluish-white metal. It is found in group IIb of the periodic table. It is brittle and crystalline at ordinary temperatures, but it becomes ductile and malleable when heated between 110 °C and 150 °C. It is a fairly reactive metal that will combine with oxygen and other non-metals, and will react with dilute acids to release hydrogen.
Zinc was known of as far back as prehistoric times and was available as a metal as early as 1374, but was only identified as an element in 1746 by Andreas Marggraf. Many origins for the name have been suggested.
The most plausible is that the name comes from the German word Zink or Zinke which translates to 'tine or sharp edge'. The mineral calamine (zinc carbonate) from which the metal can be obtained has many sharp edges. Another source suggests that 'zink' was used to denote an element that is 'not entirely unlike' Zinn which is the name for tin in German.
