CNFREE Ecofriendly gold leaching chemical is socalled nontoxic and cyanidefree gold dressing agent, which can replace sodium cyanide without changing the original equipment and cyanide process.
Thiosulfate leaching can be considered a nontoxic process, the gold dissolution rates can be faster than conventional cyanidation and, due to the decreased interference of foreign cations, high gold recoveries can be obtained from the thiosulfate leaching of complex and carbonaceoustype ores. In addition, thiosulfate can be cheaper than cyanide.
: Leaching of Gold from the Waste Mobile Phone Printed Circuit Boards (PCBs) with Ammonium Thiosulphate Literature reveals that only limited studies have been carried out to recover the metals from waste mobile phonePCBs. Ammonium thiosulfate [(NH 4) 2 S 2 O 3] is a leachant which is nontoxic as well as economical. It works to stabilize gold as

Zhichang Liu a postdoctoral fellow at Illinois' Northwestern University, and colleagues, have discovered of a new gold recovery process that's based on a nontoxic component of corn starch. This could mean an end to the need to use cyanide in many gold recovery operations.
Dec 09, 2014· HP Recovery Manager is a freeware recovery management software app filed under backup software and made available by Hewlett Packard for Windows. The review for HP Recovery Manager has not been completed yet, but it was tested by an editor here on a PC and a list of features has been compiled; see below.
Nonwires solutions have the potential to reduce customers' electric bills, improve reliability, and defer capital infrastructure. We've identified several opportunities to create such change.
The use of cyanide has generated environmental concerns because of its toxicity and therefore research on alternative gold recovery processes using nontoxic reagents is considered. The key candidates are: ammoniacal thiosulphate, thiourea and halide solutions.
Gold recovery process from Ceramic CPU's Part 1. anymore, therefore, the time will come when they will extinct from your regular electronic scrap stream. Scrap Ceramic CPU may have two values, that is, one value for scrap which represent the gold (and Silver) content and the other value, a collectors value. Yes,...

May 14, 2013· Making gold green: New nontoxic method for mining gold. The new process also can be used to extract gold from consumer electronic waste. Current methods for gold recovery involve the use of highly poisonous cyanides, often leading to contamination of the environment. Nearly all goldmining companies use this toxic gold leaching process to sequester the precious metal.
