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.
There are a large number of different kinds of gangue minerals, and each of them has its own tale to contribute to the story of the chemistry and geology of a deposit.
...we will continue our examination of the rich streams and mining districts, and then take a look at some of the big nuggets that have been found here.
