Here Is The Correct Way To Effectively Recognize Gold Ore

Most of the gold found by miners is taken from gold ore, not nuggets or flakes. The ore is usually brown, a metallic iron color, or mixed with a large white quartz rock that has very little gold in it. Gold is heavy and highly malleable. Gold will not change color, crumble, or tarnish, and is unaffected by most solvents.

Most ores, however, are made up of hard, tough rock masses that must be crushed before the valuable minerals can be released. In order to produce a crushed material suitable for use as mill feed (100 percent of the pieces must be less than 10 to 14 millimetres, or 0.4 to 0.6 inch, in diameter), crushing is done in stages.
