This is the gold I collected in a bucket over three months. Sort the gold into circuits that need cleaning, gold plated parts, gold plated pins, gold fingers, and solid gold large and small. Use a magnet to separate all gold plated steel this needs a different process than I am demonstrating.
resulting gold cyanide complex ions are then concentrated and separated from the slurry by adsorbing onto activated carbon. Elution is the next step in the process, whereby the adsorption of the gold cyanide complex onto carbon is reversed. Loaded carbon is removed from the CIL circuit and the gold stripped from the carbon using a
Gold in these circuits occurs as a layer over a base metal substrate such as nickel or copper. Separate the goldplated metal parts in the circuit boards using a magnet. Some goldplated parts may be inside ceramic components. Put on the goggles and gloves. Place all of the recovered circuit parts in one of the glass containers.
Gold has a special place among metals. It is the oldest metal exploited by man, it plays an important role in world economics, it is highly prized, it was the ultimate goal of alchemists, and it is stored in the vaults of banks. Gold has been used in gilding, to make funeral masks, and for many other uses.
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 nonrefractory gold is readily accessible for cyanide leaching, There are several variations of comminution circuits used in the gold leaching industry, such as: Multistage crushing, then ball milling circuits, typical of ball mill and hyrocyclones.
The CIL (Carbon in Leach) circuit is an intermediate stage in the production of gold. The process involves dissolving the solid gold particles into solution using a process know as cyanidation. The dissolved gold in solution is adsorbed onto activated carbon. When the carbon is loaded
The grinding circuit is a twostage process with an open circu it rod mill and a closed circuit ball mill with sizing cyclones. The coarse gold is recovered from the grinding circuit using two Knelson Concentrators. The gold is concentrated on a shaker table and sent to the refinery at .

I need to know how to Remove Trash from Recovered Gold Rich Carbon. Kindly share your ideas on how to remove excess trash specifically wood from recovered carbon in CIL circuit prior to gold elution.
The carbon is then cooled, screened to remove fines and is ready for reuse. Fines are not desirable in carbon circuits, since they will escape through the carbon screens and end up in the leach, capturing gold that will not be recovered. For this reason, high quality and hard carbon is generally utilized for these applications.
Amayapampa Gold Property For LionGold Corp. Ltd 713009 136 As well as the ROM pad and part of the comminution circuit, The Stage 1 CIL and carbon stripping / gold recovery circuit will be utilized in Stage 2. Stage 1 services will also be .
The CIL process is viable if there is sufficient gold content, carbonates/clays in the ore which will "rob" some gold in solution, and it leaches in 813 hours. A Stainless Steel Cathode from the electrowinning cell in the gold room. Notice the gold that has plated onto the surface of the stainless steel mesh.
Printed Circuit Board Recycling Methods 1. Introduction to Printed Circuit Boards The Printed Circuit Board ... typically gold (Au), silver (Ag) and platinum (Pt). ... industry is to heat the sludge to 600750°C to remove the excess amount of water and to convert the copper hydroxide to copper oxide.
terms what activated carbon is all about and how it adsorbs gold. The understanding of the mechanism of gold adsorption is important because the CIP/CIL processes work as a result of the gold adsorption mechanism, which is a chemical occurrence. Factors that affect the adsorption of gold are discussed. Finally, performance monitoring methods
CIL process is widely used in the mining industry and in particular, it is an integral part of gold extraction plant. It is a continuous process in which gold is recovered by cyanide leaching of ore slurry and simultaneous adsorption on activated carbon in agitated tanks ().From the time CIL process was introduced in the gold processing, a lot of progress and modifications have been made in ...
Gold Recovery Correctly: I will detail a SAFE process of turning old electronic parts into little round lumps of pure gold. There are many tutorials that claim to offer methods of gold recovery such as "Cupellation"*. These processes are DANGEROUS and put the user at t...
Lower gold grade oxide ores . are processed through the heap leach operation and the higher gold grade ores are treated through the leach/CIL circuit. this circuit comprises crushing, milling, cyanide leach, CIL followed by cold elution, hot elution and electrowinning. This discussion focuses on the leach/CIL circuit, where measures were in ...

How to Extract Gold From Electronics: In this Instructable, I will show you how to extract gold from computers using products most people have lying around in their homes. The way I extract the gold is relatively straightforward and pretty easy, but the chemicals used are very danger...
CIL stands for carboninleach. This is a gold extraction process called cyanidation where carbon is added to the leach tanks (or reaction vessel) so that leaching and adsorption take place in the same tanks. CIL is slightly different from another gold extraction process called CIP or carboninpulp process.
