Fools Gold Mineral

The mineral pyrite, or iron pyrite, is iron sulfide with the formula FeS2. Glittering metallic mineral is pale-to-normal, brass yellowish hue, and often also earned the nickname as a stupid gold due to its resemblance to gold. PHYRITE name comes from the Greek (purit─ôs), "fire" or "in fire", from (pur), "fire". In ancient Roman times, this name was applied to several types of stone that will create a spark when struck against steel. Pyrite is usually found associated with other sulfides or oxides in quartz veins, sedimentary rock, and metamorphic rocks, and also in coal beds, and as a replacement mineral in fossils. Although dubbed the dumb gold, pyrite is sometimes also contain a small amount of gold in it. Gold and arsenic occurs as a coupled substitution in the pyrite structure. In the Carlin gold deposit, Nevada, arsenian pyrite contains up to 0.37 wt% gold.

Electrowinning For Gold Mining

Electrowinning is an electrochemical process used to reduce the metal cations to the cathode surface of an aqueous solution derived from the chemical leaching process. Electrowinning or often referred to as electroextraction is the electrodeposition of metals from ore minerals that have dissolved into the liquid and will be processed using Electrorefining to remove impurities from the metal. Elektrowinning an electrolytic process that is very old in the mining industry. The English chemist Humphry Davy first obtained sodium metal in the form of the element in 1807 by electrolysis of molten sodium hydroxide. And then in 1847 Maximilian, Duke of Leuchtenberg first to show an experiment about Electrorefining copper. Then James Elkington patented a commercial process in 1865 and successfully opened the first factory in Pembrey, Wales in 1870. The first commercial plant in the United States is Balbach and Sons Refining and Smelting Company in Newark, New Jersey in 1883
     Electrowinning is applied to a variety of chemical solutions that are found in large mining industry. This process involves the use of alkaline cyanide solution as an electrolyte in a cell as the anode and cathode, among others, can use:

How The Extraction Of Gold By Method Of Carbon In Pulp

Gold processing methods with the Carbon in pulp are often used in large-scale gold mining processing, where the active carbon in pulp method used for recovery of gold ore minerals in the washing tank. Tanks that are used are usually equipped with an agitator and air bubbles equipment and tools are designed to maintain solids in suspension in the slurry, and the achievement of leaching. In the process adsorption ore minerals in the soil material condition of the tank should be good enough to form a slurry that can flow under gravity or when pumped. To form a slurry, mineral ore in the mix with water and the reagent was added to the tank to get the gold leaching reaction
How to work the gold extraction process with carbon adsorption in the pulp can be explained by the following system
     

Extracting Gold By Carbon In Pulp


        Carbon In Pulp is the absorption of compounds into carbon Dicyano Aurrat.In the process of carbon-in-pulp adsorption occurs after the leaching of mineral ore slurry in a tank. And during the washing, the carbon-in-leach and adsorption occur simultaneously. In both processes mineral ore leaching slurry will be transferred from one tank into the recovery tank of carbon using a pumping machine. This is generally accomplished by passing the slurry through a series of adsorption vessels coupled with the periodic transfer of carbon, usually associated with pulp, and in the opposite direction. Column tanks are often used consists of a large carbon column (diameter 5 to 8 feet) and 15 to 20 feet in height, and filled with activated carbon. Minimum load of carbon rule of thumb is one pound of activated carbon per 0.1 ounces of gold are present in solution, and usually it's a few pounds per 1 / 10 ounce
         Two main methods Carbon In Pulp (CIP) and Carbon Columns may consist of the most widely used technique for extracting gold today. Both methods use a large tank in the column parallel step where gold is dissolved in the slurry (pulp) through a chemical process and combine agitation, oxygen and cyanide. In CIP, the carbon is mixed with a solution of cyanide leach and ore agitated in the Tank leaching, and the adsorption process will separate the gold. This will bring together between carbon and gold cyanide solution which is attached to the carbon. Granular carbon is often hard to use in a variety of sizes between 10-16 mesh. Carbon is then filtered by using the screening, on-screen screening of carbon will settle and the liquid is finely ground ore (-100 mesh) will be screened out through the screen into the tank.CIP treatment system can be described simply as a picture diagram below:
