gold recovery by ion exchange resin in europe

Gold recovery with ion exchange used resins -

2001-6-1  The objective of this work is to demonstrate that a weak base ion exchange resin taken as spent in a demineralization plant can be used for gold recovery from diluted alkaline cyanide solutions with no pH correction. Moreover, the low-volume solution resulting from the elution step is appropriate to recover gold through electrowinning . Thus the useful life of these resins can be prolonged, the precious metal recovered

gold recovery via ion exchange resins; ALTA 2017

Ion exchange resins, that are semi-selective for gold, have been extensively used for gold recovery from cyanide leach processes in the former USSR. Despite forward looking statements by researchers and technology vendors, there have been very few applications in Western plants. Historically, the difference in economic drivers, relative ...

TECHNICAL PAPER - Ion Exchange Resin Manufacturer

2020-2-10  Gold-Selective Ion Exchange Resins While the Western World has been slow in adopting IX resins for gold recovery, several operations have successfully implemented the use of resin-in-pulp/resin-in-leach (RIP/RIL) in recent years. These include Avocet Mining’s Penjom Gold Mine in Malaysia and Anglo Asia’s Gedabek mine in Azerbaijan.

Technology Innovations Nano Gold

Ion Exchange Technology is one of the unsurpassed possible way-out for the recovery of precious metals from waste or low-grade streams. This technology allows the recovery of the precious metals to extremely low levels (micro grams/liter) with relatively high upgrade ratios from the solution onto the resin without major water balance concerns, while the impact on the environment could be minimized or avoided.

Recovering gold from plating drag-out by ion

2014-5-11  You should have no problem recovering gold using strong base anion resin. The only strong "chelator" in most gold baths is cyanide, unless you are using a sulfite system, or you have a acid gold chloride strike. The gold is in the form of a gold cyanide complex which exchanges quite nicely. And free cyanide comes out on the SBA resin as well.

APPLICATION OF ION EXCHANGE RESINS IN GOLD

2018-6-10  The application of macroporous strong base resins to cyanide recovery from synthetic solutions containing ferrous cyanide, nickel cyanide and high levels of copper cyanide is discussed. Adsorption experiments show that strong base resins readily extract metal cyanocomplexes, in a sequence of affinity given by Ni>Cu>Fe, for polystyrene resins, and by Cu>Ni>Fe, with polyacrylic resins.
