Gravity concentrators produce gold from ore in a matter of minutes or hours rather than days or weeks. By introducing concentrators into your circuit, you can experience faster recovery times, allowing you to produce gold more quickly, which in turn improves your cash flow. Process Optimization
This green method extracts gold from crude sources and leaves behind other metals that are often found mixed together with the crude gold. The new process also can be used to extract gold from consumer electronic waste. Current methods for gold recovery involve the use of highly poisonous cyanides, often leading to contamination of the environment.
Cyanidation: It is one of the main methods of gold extracting process. 1 Contact finely ground ore with the solution containing cyanide. 2 Separate solid from the clear solution. 3 Recover gold from the solution with zinc powder by precipitation. Video of cyanide gold process production line.

Metallurgical processing of metalliferous ores in general and gold ores in particular, consists essentially of three stages, often colloquially referred to as: Bashing (crushing); Mashing (grinding); and Hashing (extraction/recovery) In the context of flowsheet selection, the bashing and mashing stages are relatively straightforward.
A new technology called Chrysos PhotonAssay that uses high-energy X-rays to determine the gold content of mineral ores could now challenge the pre-eminence of fire assay. T he technology, also called gamma activation analysis, was invented in the 1960s, but its lack of sensitivity and accuracy limited its widespread application.

Here's how we do it -- Situation #1: The process we use is not to get free milling gold (which is difficult without chemicals, the gold is often plated on the pins/fingers), but works to obtain a metal concentrate of the base and precious metals (Cu, Au, Ag, Pd, Pt, etc) which are present in boards. The concentrate can then be sold or refined.
