Apr 14, 2015· A sluice box recovers gold as a concentrate which has greater gold content. Recovery is a process of eliminating non-gold products from gold. Gravity methods rely on separation based on mass. The particles must have nearly equal size and different mass to be separated. There is a limit to the process of screening to smaller and smaller particle

Gold fingers are typically found on PCI cards, ISA cards, or on Memory sims/dimms/etc. They create the corrosion free connection between the computer and the expansion card. This process can also be used to recover gold from CPU such as Pentium Pro, or Cyrix or older 486 and lower generation chips.
Scalping gold from concentrate products Placing gravity recovery in a single pass scalping application (not within a grinding circuit) can sometimes be very economic. Any gold removed previously by gravity in the primary or regrind milling circuits will affect the content and nature of gold in the final concentrate products; therefore care

Smelting and Roasting Gold and Silver sulfide Ores to recover values: . It could also be used with small lots of sulfide concentrates. On the other hand, there are alternatives for processing sulfide ores. The way the Spanish did it, the old patio process -
gold and 0.7% copper. This equals the recovery of 87% gold and 98% copper, respectively. The gold-containing solu-tion was pumped through small carbon columns that removed gold down to a level less than 0.02 mg/L. Another commercial chalcopyritic copper concentrate containing 23.5% copper and 4.3 ppm gold was studied
This pushes the gold foils off the filter and into the cup. Then, wait for the gold foils to settle to the bottom and get as much water out. After that, you could wait for the water to evaporate out and you are left with just gold. However, the gold foils tend to stick to the cup, so I keep mine in a glass vial with some water.

Nov 19, 2009· Q. Sir, I am doing the scrap gold. I got a problem in gold recovery that is, actually I am using the method of collecting the gold coated material and adding the nitric acid and giving the heat. After boiling the acid, the gold layer appearing the top, collecting the gold layer, when I try to heat that gold it becomes nothing.
Gold in concentrate attracted a 2% treatment charge and late payment which, at AUD$450/oz, represented about AUD$290,000 /y treatment costs and AUD$1.8M in operating capital. This was a considerable economic incentive to maximise gravity gold recovery. There was considerable potential to increase gravity gold recovery.
