Heavy Sands Mining

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.

The Birimian Greenstone Belts of West Africa

The country we were to visit was Burkina Faso, a small country about the same size of my home state of Nevada with about 10 times more people. The second day I was in Africa, we went out to the goldfields for the first time.

All About Minerals

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.

Alaska: Kodiak Islands Mineral Resources

The fresh material is worked and concentrated by the waves on the flat, wide beach platform. The waves wash away the lighter minerals, leaving the heavies near the bluffs and in depressions on the beach.
