Prospecting for Copper Ores—Part I
June 2012 by Chris RalphCopper is one of the metals that form the backbone of our modern civilization. Copper is an essential part of every computer, cell phone, automobile and household appliance.
Guyanese gold deposits occur in deformed and metamorphosed greenstones made up of alternating mafic to felsic volcanic and sedimentary rocks intruded by granitoid basoliths and stocks.
Ivory Coast has considerable gold reserves, and this nation has the largest area of greenstone belts prospective for gold in the continent.
Two miners were killed in an accident partly because someone wedged a broom handle against a reset button to bypass an alarm that would have shut down the system, federal safety investigators said.
The metal is expensive, not because it is rare but because of the expense to produce and work it. The minerals mined for titanium are all oxides, unlike many base metals that are mostly mined as sulfide minerals.
A Wilfley table works best when all of the mineral being run across it (the pulp) is about the same size. For this reason, I took a good look at each of the samples.
Mining has returned to Nevada’s historic Comstock more than 150 years after the discovery of one of the world’s richest silver veins touched off a frenzy that drew thousands of people west. But unlike the hard rock miners in the 1800s, the modern day operation involves huge trucks...
...most prospectors don't even think about the conductivity of minerals, but there are some that do conduct electricity to a certain degree, so metal detectors will respond to them.
