Critical Metals: Antimony
June 2016 by Chris Ralph
I’ve been taking a look at the mining and uses of a number of critical metals in series of articles, and it’s time to take a look at antimony.

Flood Plain Gold Deposits—What Are They Really?
November 2017
We just completed a trip to another river, and yes, there was definite movement and redistribution of gravels, and other prospectors have seen this as well.
Enrichment of Mineral Deposits by Weathering—Part II
April 2016
While both zinc and lead deposits also are enriched by the surface weathering process, in part two we will look at the enrichment process for copper and also gold deposits, and at the interpretation of leached outcrops to figure how rich the concentrated deposits below them may be.

Understanding and Prospecting Benches
September 2011
The most obvious benches are usually near the valley floor, but they can be thousands of feet above the valley floor. Since benches were made by streams, they can contain placer deposits.

Prospecting for Nickel Deposits
November 2010
The periodic exploration efforts for nickel during periods of high prices have been sporadic and incomplete. There is a role for the prospector and geologist in searching laterites potentially rich in nickel and mafic igneous bodies that may be rich in nickel.

Heavy Sands Mining
February 2013
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.

Gold in Quartz
February 2016
Because quartz and gold may be deposited together across a considerable range of temperatures, not all quartz veins are the same, and there are several different types of gold-quartz deposits.
