Microblog: No 1 Gold Stock Mark lichtenfeld Stock Gumshoe

01/06/2021 These tailings are also filled with leftover gold missed in the initial operation. The #1 gold company can actually clean up the tailings, extracting millions of ounces of gold while doing so. It’s created a process called “nano-extraction” that allows it to run tailings through its “retreatment plants” and pull out huge amounts of gold.

Man-Made Gold Indicators How to Identify Past Mining

08/08/2014 One of the types of historic mining that is easiest to identify is tailing piles left behind from dredging operations. I am not talking about a modern suction dredge; rather we are talking about the huge bucket-line dredges, drag-line dredges, and smaller “doodlebug” dredges that were so commonly used in the rich gold bearing areas mainly during the early to mid-1900s.

Mine Waste Transfer and Disposal Methods Mine Tailings

In response, mining engineers have developed clever ways of waste management, making the mining industry one of the few that actively recycle their own waste. Overburden is used for reprocessing, contouring land, and as a construction aggregate for buildings and roads. Mine tailings are reused for producing clay, tiles, glass, and concrete.

Cyanide is one of the few chemicals that can dissolve gold. At Ballarat Gold Mine, cyanide is chemically destroyed to harmless levels before the tailings is deposited in the TSF. Arsenic. Unlike cyanide, which is a chemical reagent purposely added to extract gold, arsenic is a naturally occurring element within the rock mined underground. Unlike cyanide, it cannot be destroyed or detoxified

Prospecting Gold Tailing Piles with a Metal Detector

Well, unfortunately there is one serious challenge with metal detecting in old dredge tailings trash! Most dredge tailings are absolutely littered with iron trash, from square nails and boot tacks, all the way up to 55-gallon oil drums! The old-timers just didn’t give much thought to littering, and it is clearly evident once you start swinging your detector across some tailing piles.
