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.
Undiscovered Placer Deposits in Alaska
These conditions don’t just apply to Alaska and the Yukon; they apply to western Canada and even to the mountainous western United States.
Critical Metals: Lithium

Enrichment of Mineral Deposits by Weathering—Part II
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.
