The Mining Towns of California

Posted May 15, 2012 in Mining Camps & Cities
Tourists will naturally desire to visit some of the towns, where they can observe closely the various operations connected with gold-mining, which is such an important industry of California.

The Amalgamator - Skidoo 1909

Posted April 04, 2012 in Mining Camps & Cities
In the early days of lode gold mining, stamp mills were used for crushing the ore. Where there was free gold in the ore, a silver-plated copper plate was placed so that the discharge through the screen from the mortar, with the addition of water, flowed down over this plate which was coated with quicksilver, allowing the free gold to become amalgamated and retained on the plate. The man who operated such a mill was called an amalgamator.

The Ingersoll Rock Drill (1874)

Posted July 21, 2009
The substitution of a mechanical power in place of the hand-labor formerly exclusively used for drilling rock, has been a subject of much thought, and many attempts have been made, with greater or less success, until the rock drill by improved machinery became of late years a firmly established institution, and the credit of this belongs, to a great extent, to the improvements made by Mr. Ingersoll, as he overcame the defects connected with former attempts, which were excessive weight, imperfect action, easy derangement, frequent damage, and costly repair.
