If you crush mica you will get a white powder. It might be colored by iron so it would look like a yellow powder, but washing it in an acid (HCl, oxalic acid, citric acid...) will remove the iron and only leave the white powder. Crushing gold is really hard since as anachronism pointed out, gold is malleable and will only deform and smear.

In order to extract pure gold, refiners put the ore through a multi-step process. In the first step, the gold ore is crushed and ground into a fine powder. This step increases the surface area of the ore, allowing for better extraction of the gold particles. The next step is to separate the gold from the other elements in the ore.

Typically, gold is encapsulated or finely disseminated in refractory gold ores and the direct cyanidation is not effective for gold extraction from these ores, even after the ore is ground to exceeding small particles (Nazari, 2017, Corrans and Angove, 1991).Especially for sulfide refractory gold ores, in order to recover gold, many …

After gold-containing ores are mined via the hard-rock method, they are crushed into smaller, gravel-sized bits, which are then cycled through rotating drums where steel balls grind them down even further. Eventually, a fine powder-like material results, to which water is added, creating a "slurry" or "pulp" substance.

With some borax, heat, and a little know-how, it's possible to extract pure gold from a sample of ore. This is because using borax as the flux reduces the melting point of all the elements in a piece of ore, including gold. While out in the field, a gold prospector can grind and wash a piece of ore, then mix it with borax in a plastic bag.

In panning large samples, only one or two specks of gold could be seen, although the ore contained from 1 to 2 ounces per ton. This ore yielded only about 40 per cent, on being amalgamated, but over 90 per cent, was dissolved out by leaching the raw ore with cyanide of potassium, and similar results were obtained by chlorination.

Leaching dissolves the gold out of the ore using a chemical solvent. The most common solvent is cyanide, which must be combined with oxygen in a process known as carbon-in-pulp. As the cyanide and oxygen react chemically, gold in the pulp dissolves. When workers introduce small carbon grains to the tank, the gold adheres to the carbon.
