Since there is far less silver than reflected in that ratio there would be a mad rush out of gold and into silver. It won't work. If silver and gold are to be used as money they must be allowed to float against each other relative to supply and demand. In this respect silver should fly by gold in the new backed currency. 1oz SILVER/GOLD BACKED CURRENCY = $100 in relation to $50 Gold Eagles

If we can recall back to our high school chemistry classes, we might remember that in its purest form gold is actually an element, notated by the symbol AU on the periodic table of elements. Gold
Smith is projecting that gold could reach US$10,000 per ounce by the end of the bull market. At a gold/silver ratio of between 60:1 and 40:1, silver would be valued at US$166 to US$250.
Placer gold was discovered in California in 1848, and mercury in 1850, a convenient circumstance. Still more thorough recovery is possible with the cyanide process, introduced in 1893. Gold is recovered as sodium aurocyanide, NaAuCN 2 on leaching of the concentrate with NaCN, sodium cyanide. The amount of gold recoverable by cyanidation of
23/01/2011· The company proposed to recover gold by heap leaching the tailings.

In 1995, production from the tailings totaled 93 kilograms of
Heap leaching helps recover gold from ore that would otherwise be too expensive to process. Other . Another process involves ground ore being passed over plates which are coated with mercury. The gold and the mercury form an amalgam, leading to the name of the process, amalgamation. Once the amalgam has formed, it is heated until the mercury gas is boiled off, leaving the gold. The mercury

Leaching, often gold, is the process of extracting a soluble constituent from a solid by means of a solvent. In extractive metallurgy, of gold, it is the process of dissolving a certain mineral or minerals from an ore or a concentrate, or dissolving certain constituents from materials such as a calcines, mattes, scrap alloys, anodic slimes, etc., to achieve either one or two purposes

Leaching Gold With Cyanide Since the 1890's, cyanide has been used to recover gold from gold bearing ores. And today, over 115 years later, most of the worlds gold is recovered with cyanide playing a large part in the beneficiation of the yellow precious metal. Chemically, it is a rather simple reaction: 4 Au + 8NaCN +O2 + 2 H2O = 4 NaAuCN2 + 4 NaOH That presumes that the only elements
Jackman and Sarbutt 1990 found that solution changes during leaching gave a dramatic improvement in gold recovery on a 74 mm goldtellurium concentrate grading 218 g/t Au, 410 g/t Te and 41.7 S, the major tellurium mineral being montbrayite . Gold recovery improved from 92 to 98 with two solution changes. The presence of carbon in leach process CIL was shown to achieve a

reach gold surfaces. Several authors studied gold dissolutionics. Some considered pore diffusion transport in heap leaching Prosser1, Bouffard and Dixon2 while others addressed the leaching problem by the concept of gold surface liberation. In those conditions, experimental results showed a reduction of leachingics as the chemical reaction advances. To model that behaviour, many

The reason that the various gold leaches are not used on high grade concentrates is that these leaches are all dilute solutions, and usually will not hold enough gold to get all of the gold out of a concentrate but that isn't the only problem.
CIL gold processing plant mainly consists of following steps: 1 The ore is first reduced in size typically 90 passing 200mesh to ensure that all non refractory gold is readily accessible for cyanide leaching, There are several variationsminution circuits used in the gold leaching industry, such as: Multi stage crushing, then ball milling circuits, typical of ball mill and hyrocyclones.

Depending on the material a lift can be 10 or more meters and the pad can reach several hundred feet. Most miners use a simple drip irrigation method to wet the pad.
