Esfandiar! I have been following you since the beginning. You have made great progress and congratulations. Your first videos were of low quality and I did not understand. But now I am learning a lot and I am waiting for your next videos. By the way, I have failed in working with cyanide and have not been able to do a proper extraction. I am waiting my good friend🤑🤑👍👌

Gold stone :
Dear channel members,
Here are some upcoming videos currently being recorded and edited:
Testing mineral ore using cyanide — including extraction and precipitation of elements in cyanide solution.
Testing mineral ore using thiocyanate — including extraction and precipitation of elements.
Extraction from cyanide solution using electrolysis — converting directly to metallic gold.
These videos will be exclusively for members.
Technical Notes:
Some questions in the comments asked about the difference between gold sulfide and pyrite, which I will explain in detail.
Pyrite consists of sulfur and iron.
Sulfides consist of elemental ions combined with sulfur — for example: gold sulfide, mercury sulfide, rhodium sulfide, and so on.
Most elements in the periodic table can form sulfide compounds.
When you see various beautiful colors in a mineral sample, it usually indicates the presence of different elemental ions.
Many future experiments will focus on this topic.
