I might have read something about Sileach and the application to gold processing.
The following news link is an example about what I was talking about recently:
https://finfeed.com/mining/lit/lit-...le-loop-advanced-battery-technology/20170904/
Towards the end of the article it states the following:
-------------------------------------------------------------
This versatile technology (SiLeach) also has applications beyond the recovery of lithium from silicates. For example, it has been tested on refractory gold ores to remove siliceous gangue material from the ore prior to cyanide recovery of gold.
This versatility suggests that SiLeach® could become the benchmark for extraction of a wide range of metals from silicates.
------------------------------------------------------------
I was implying over the weekend that Sileach might be applicable to epithermal gold deposits. Its all good.!!!
