Hello DmitriyQuantum,
In one of your posts you say:
My native language is russian. I dont clearly understand what help I need. May be I need advices from people, who have good experience in the gold refining processes.
Apparently you have two problems. One, the minor, is your mother language, Russian, which probably is not understood well enough by every people you are working with in your company, and the company, you represent as an authorized distributor, Agilent-Technologies. - Speaking of your company - is this in fact a company, you are owning and managing yourself, or is it a company, you are working for?
From what you have written until now, I can derive only, that your primary job in the siberian gold refinery factory, - modernization, improvement of quality control, analytical department, laboratory and supply with appropriate analytical instrumentation, - is more or less done, and therefore new challenges, namely the amelioration of the whole production-situation, are waiting for you. This seems to me to be your second, the bigger problem, to be not familiar with recovery/refining and production/process related problems.
As 4metals mentioned already, Siberia has mines yielding gold and platinum ores. One of the biggest global PGM-producers is Norilsk Nickel.
