The Small Hardrock Mill—Part II
August 2006 by Del Thomas, MEWelcome back to our mining claim. In part one we located our claim, sunk our shaft, and stored some ore in the ore bin. Now we must decide how we are going to extract the gold. We briefly discussed setting up a lab in a 40-foot semi-trailer at the mine site, so let’s decide what we are going to need in the lab.
A recent online survey on our homepage confirmed what we expected...
- Ex-husband has money to burn
- Define “emergency”…
Tabling and jigging are two relatively inexpensive methods of recovering the “free particle values” from the noble metal ores. However, not all ores contain their values as free particles. In fact, many gold ores contain appreciable amounts of “metallic gold salts,” some of which readily dissolve in the system water and continue to migrate right along with it.
Excerpts from California Mining Journal, our original title, published 50 years ago this month.
Mexico is a large country, much larger than the state of Alaska. It is almost as long as the US is wide. It has climates that range from tropical rainforests in the south to barren deserts in the north. The Sierra Madre is a forested plateau that reaches elevations in excess of 10,000 feet. It parallels the west coast of the country.
