Apr 24, 2017· Allow four hours for the gold to dissolve, stirring every 20 minutes. The chlorine reacts with the gold inside the ore to form gold chloride. Filter the ore and bleach solution to remove all the impurities, such as soil and rock fragments. Collect the filtered gold chloride solution in a flask.
It is not used much anymore, because most leaching is heap leaching, carried out in the outdoors, where drip emitters or sprays distribute the cyanide solution to a large structure of gold ore, called a "heap". And while the pile of ore is called a heap, it is not a haphazard pile of rocks.
Eco-Goldex O-series ; The O Series (it refers to Ores) is specially formulated and manufactured with the purpose of replacing the toxic sodium cyanide in gold/silver/PGM rock ore leaching. The O series can compete sodium cyanide easily in most rock ore processing including gold leaching rate (similar or even better), agent consumption (similar or slightly higher) and leaching time (similar or ...

I recently tested the Eco-Goldex product (Os series) on a lab scale with promising results. It was a sulfide gold ore with 30% silver from a friend's mine. He wants to scale up the process to leach whole ore in vats or tanks but it requires a finer grinding method (ball mill) to replace the Chilean mill he has now.
I visited a plant in Malaysia (Penjom) where this was such a serious problem that they had to use kerosene to foul (blank) the organic carbon prior to cyanide leaching. They used a resin in pulp system then for the recovery of gold which worked very efficiently such that they were able to profitably treat the ore and recover the gold.
Gold recovery increase in CIL circuit. Various trials have shown the potential of PIONERA BioPolymer to increase metal recovery in leaching circuits. This is especially relevant in the CIL/CIP circuits used in gold processing. The benefit of PIONERA BioPolymer is also observed in the Merrill Crowe process.

Bioleaching is the extraction of metals from their ores through the use of living organisms.This is much cleaner than the traditional heap leaching using cyanide. Bioleaching is one of several applications within biohydrometallurgy and several methods are used to recover copper, zinc, lead, arsenic, antimony, nickel, molybdenum, gold, silver, and cobalt
A diagnostic leach test can be very useful to qualitatively assess how gold occurs within the ore and the extent to which it may be refractory. Several different permutations of diagnostic leach tests depend on specific objectives, but they generally involve the sequential leaching of a gold ore sample with progressively stronger reagents, producing a qualitative assessment of the gold ...
