The Importance Of Mining Critical Minerals In The USA
March 2019 by Chris Ralph
Critical minerals are products that the government has designated as critical to our national interest because of both their potential military and industrial applications.
Critical Minerals: Titanium
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.

Persistence Leads to Over a Pound of Gold
I have figured out over the years that the winning combination is hard work, persistence, knowledge, and a little luck. This leads me to describe one of my best finds ever, a “honey hole” of placer gold, if you will.
Small-Scale Processing of Hard Rock Ores
Depending on the ore and if significant sulfides are present, a hard rock miner may be able to get away with simply using a flux to digest the other minerals that may be present.
The Smell of Gold—Part I
Some claim they can smell gold. This may be, but when I take a whiff of gold, I smell dirt, rotten eggs, garlic or just nothing: my nose is everything but sensitive.
Mining Pegmatite Deposits
With successively lower temperatures as the water mixture cools, new sets of minerals are formed and many of those stable at a higher degree of heat became subject to alteration as the temperature progressively moved lower.
Gold in Tertiary Gravels
In some places, semi-continuous sections of riverbed can easily be linked in many places to identify the path of the ancient rivers.
