Heavy Sands Mining
February 2013 by Bill RichLately 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.
...these nuggets have not traveled far from the lode because the golden wire lattices would have been torn apart or flattened during weathering of rock and deposition by violent stream action.
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.
In some ways, silver is the forgotten precious metal because it straddles both the world of precious metals and jewelry, while having many important industrial applications like a base metal. The price of silver reflects both the precious metal investment demand as well as the industrial demand.
For approximately 30 years, the mines produced good ore, some so rich it was simply sent straight to bagging, bypassing milling and loaded directly on the rail cars.
It would seem that we are often indeed destined to repeat history. In terms of gold discovery, even with all the advancements that have been made over the years, it seems we are once again on the cusp of returning to the 1800s world of gold mining. Even as you read this, a new gold rush is taking place in a sleepy little town in South Carolina.
There are literally thousands of abandoned wasterock and ore dumps that dot the United States that could hold many tones of strategic metals.
Copper is a critically important metal that we need to run our modern electronic society, and the long term outlook for this metal is for a steady increase in price.
