Calcite and Limestone
February 2017 by Chris Ralph
The other distinguishing feature of calcite has to do with its chemistry. Geologists sometimes take a small bottle of dilute hydrochloric acid out into the field with them because calcite reacts with acids to make a bubbly foam.
Perception of Mining vs. Reality
Many modern mining companies have taken to making a special effort to ensure the goods and services they need are supplied as much as possible out of the local economy.The Many Facets of Iron
I’ve been fascinated by iron minerals for many years. So let’s take a look at this very interesting and colorful element.
Large Gold Deposit Types
It is not necessary to have a PhD in geology, but you need to know the basics, so that’s what I am going to try to dig into here—the understandable basics of these gigantic gold deposits.
Iron Ores and Iron Mining
For more than 40 years, iron ore prices have been decided by private negotiations conducted between the largest of the iron miners and the largest steel producers. These two sides dominate both the spot and contract iron ore markets.
Understanding Large Gold Deposit Types: Discovering New Mines
The other opportunity that I see is in seeking unusual types of deposits. Specifically, the prospector would be searching for the stuff no one (or almost no one) is searching for. These deposits are effectively hiding in plain view.

Strategic Metals—Part I
A bill was introduced and passed by the House of Representatives earlier this year that should make the exploration and opening of a mining operation faster and easier.
