Golden Science

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.
