To put this in perspective, one carat weighs only 0.2 gram equivalent to 0.007 ounce.the mineral-bearing the gold is known as the ore. using visual inspection alone to ascertain if it is gold can be quite difficult or nearly impossible. this largely depends on the gold concentration within the rock. several ores that contain the gold are also known to contain some other metals within them as well.

the color of pure gold is bright golden yellow, but the greater the silver content, the whiter its color is. much of the gold mined is actually from gold ore rather then actual gold specimens. the ore is often brown, iron-stained rock or massive white quartz, and usually contains only minute traces of gold. To extract the gold, the ore is many ores that contain gold contain other metallic metals in them also, so there are likely to be a lot of shiny minerals mixed into the rock which may or may not be valuable. the other challenge in visual inspecting gold ores for possible gold content is the fact that the total concentration of gold in a piece of ore is generally negligible.mar 13, 2018 take a rock that contains gold in it this process works best on quartz rocks and set it inside a glass jar. add white cooking vinegar to the jar, covering the entire rock and then some with the vinegar. the acid-based vinegar slowly dissolves the quartz crystals surrounding the gold, leaving only bits of quartz attached to the gold.
