Strategic Metals—Part I
November 2013 by Bill RichA bill was introduced and passed by the House of Representatives earlier this year that should make the exploration and opening of a mining operation faster and easier.
There are several common ways that new mineral crystals form and grow. Perhaps the simplest is when minerals form through the cooling of molten rock and the atoms bond together into mineral crystals.
It is a gemstone, and yet it is also closely associated with many types of metal ores. It's valuable itself but often points toward other valuable minerals—that is certainly something prospectors want to know more about!
There are both hard rock and beach sand types of titanium deposits, but the hard rock deposits need to be at least 10 percent titanium while the beach sands often are economic with only two or three percent titanium.
Silver nuggets have been described as “ultra-rare,” “prized” and “unique.” Naturally occurring silver nuggets are rare enough to suggest caution when purchasing. Fakes have reportedly been produced and misrepresented for sale as genuine specimens.
It also happens sometimes that glaciers will bury valuable placer deposits. This occurs when the glacier goes over the top of an existing placer deposit.
Chances are better that both types of gold did not come from the same source. Let's look at the probable conditions to cause two types of gold in a placer.
Lately my mind has been involved with group 4 of the transition elements, namely titanium, zirconium, and hafnium. They all have similar chemical properties. Of greatest interest to economic geologists and miners is that these valuable elements often occur together in sands.
