A weekly Q&A series

What is Glycine?

Answer:

A: Glycine is an amino acid that appears commonly in nature and is present in our bodies. However it is also produced synthetically and so is traded as a commodity. It is a very benign substance.

Can you buy Glycine in bulk? Is it readily available?

Answer:

Answer: Glycine is sold in different grades. This varies from high purity manufactured for the pharmaceutical industry as well as a standard bulk product which we would use for our process. The standard product is adequate for any glycine leaching application. Currently Australia does not manufacture it but is a user. China and the US are the major producers of it and there’s several other countries also manufacture it. We did a market study a few years ago that suggested that any uptick in projected use in the mining industry could be easily accommodated within the current supply/demand balance without material impact on pricing.

Does water quality affect the process?

Answer: With the testwork we’ve done so far with hypersaline and seawater we’ve seen no adverse effect. We’ve just recently had a partner complete a pilot plant using seawater and they successfully demonstrated the technology.

Can you comment on the difference between Cyanidation and GlyCat in terms of recovering gold from solution?

Answer: There’s no real difference between Cyanide and Glycat – they both require carbon to recover, and so, we’ve proven in pilot campaigns (both CIP and CIL) that we can effectively recover the gold from solution.
