Be sure to inspect the black sands as you clean them off the bottom of your magnet, as small bits of gold can be trapped and lost in this part of the process.

Gold extraction Wikipedia

A "refractory" gold ore is an ore that has ultra fine gold particles disseminated throughout its gold occluded minerals. These ores are naturally resistant to recovery by standard cyanidation and carbon adsorption processes. These refractory ores require pre-treatment in order for cyanidation to be effective in recovery of the gold. A refractory ore generally contains sulfide minerals, organic carbon, or both. Sulfide minerals are impermeable minerals that occlude gold particles, making it difficult for the leach s

Extraction of Gold

The ore is reduced to a fine state of division and amalgamated simultaneously in a stamp-mill, the solid gold-amalgam separated from the liquid mercury by filtration through leather under pressure, and the mercury distilled. Complete extraction of the gold by amalgamation is impossible, a part remaining in the mud of the stamp- mills.
