Scrap Gold Recovery Kit
In the process of gold extraction from scrap computer electronics parts, Sodium Metabisulfite is usually used along with Urea. Urea, also called carbamide, is soluble in water and alcohol and is non-combustible. In gold recovery processes, it is used as a neutralizer of excess nitric acid in aqua regia solutions.

The carbon is then generally subjected to a heated solution (200 deg to 250 deg F) of (1%) sodium hydroxide and (0.1%) cyanide and the gold is re-dissolved and removed from the carbon surface. At this point, the NaOH/CN solution is sent to electrowinning cells, where the gold is plated onto stainless steel cathodes. The gold is removed from the cathodes by either using a high pressure water

Reference: Mesh Micron Conversion Chart
Mesh size is not a precise measurement of particle size. What do the minus (-) and plus (+) plus signs mean when describing mesh sizes? Here’s a simple example of how they work. –200-mesh would mean that all particles smaller than 200-mesh would pass through. +200 mesh means that all the particles 200-mesh or larger are retained.

Mesh Sizing Chart. Mesh size for strainers is usually denominated in mm or microns however it can also be assigned a mesh number (which is number of holes per inch). A micron is one millionth of a meter. There are some basic references of size of mesh but vary according to such things as heat, pressure and the nature of the material.

Coarser material can have more material put in the bowl. 100-, only about a rounded tablespoon full. Hope this all helps.
