How to Extract Gold From Electronics : 11 Steps (with

I have scrap gold chains, gold ring, many old cell phones, including sim cards, some computer motherboards I like to process to extract the gold & silver. But I dont have the space, means or time to do this myself. Question: is there any place who will extract it and melt gold/ silver extracted into bars for a few. Would it b worth time. Thanks

Elution and Carbon Reactivation Resource book

During the CIL process, gold is leached from the ore using an alkaline cyanide solution. The resulting gold cyanide complex ions are then concentrated and separated from the slurry by adsorbing onto activated carbon. Elution is the next step in the process, whereby the adsorption of the gold cyanide complex onto carbon is reversed.

For example, complex gold in a sulphide complex of pyrite, must isolate a specific gravity of 19.3 for gold from 5.2 for pyrite. Using gravity to recover minerals in their coarsest fraction minimises over-grinding and prevents losses due to excessive comminution, and during multiple processing steps.

The primary reason for the significant comminution circuits is because in gold mining the grades are notably low and thus excessive waste material is present, resulting in high mill feed rates. If the ore rock is highly fractured and/or brittle, it is likely that an AG mill be the most economical option in lieu of a
