Large Scale Mining
Extraction of Precious Metals Using Froth Flotation
December 2012 by Bill Rich
Without this versatile group of technologies, we would be hard-pressed to produce the metals so critical to our modern way of life. The robust mining industry of today would literally not exist.
What About Palladium?
Palladium may well be an underexplored element and therefore an opportunity for prospectors and geologists. This is because they are often less than obvious and other than the native metals, a chemical analysis of samples is required to identify PGM-enriched rocks.
Resurrecting an Old Hard Rock Mine—Setting Up the Millsite
One of the first things we did while looking at buying the equipment was figuring out how it would dovetail into the milling process we already had in mind.
Care and Lubrication of a Model 13 Laboratory Wilfley Table

Critical Minerals Update

An Update On The Father's Day Gold Discovery
Just recently, the miners hit another big pocket, this time with nearly 1,000 ounces of gold. Some of the rich specimens were as big as a fist and others were in the form of smaller pieces.
Underground Mining: Getting the Ore Out
Choosing the right method to move your ore and waste is all about making the right choices. Sometimes more than one method may be used during the life of a mine as an operation expands and grows.
