## How gold is made history, used, parts, procedure

A karat is a unit equal to 1/24 part of pure gold in an alloy. Thus, 24 karat (24K) gold is pure gold, while 18 karat gold is 18 parts pure gold to 6 parts other metal. Extraction and Refining Gold is usually found in a pure state however, it can also be extracted from silver, copper, lead and zinc.
