If this copper is crushed to produce a clean stream for flotation process, we end up with the powder that looks like this. After flotation, we produce a stream of tailings that looks like this and a stream of recovered ore that looks like this. Flotation is a powerful tool to recover small amounts of valuable minerals from low grade ores.

The Fire Assay Method, otherwise known as the Cupellation Method, analyzes gold with the highest level of accuracy. Measuring between 2 and 3 parts per thousand, this method involves the use of a sample size of usually 0.25 of a gram of the substance in question. Most hallmarking authorities around the world employ the Fire Assay Method.

A stamp mill consists of a set of heavy steel (iron-shod wood in some cases) stamps, loosely held vertically in a frame, in which the stamps can slide up and down. They are lifted by cams on a horizontal rotating shaft.As the cam moves from under the stamp, the stamp falls onto the ore below, crushing the rock, and the lifting process is repeated at the next pass of the cam.

That takes some time to do in a prep lab. In that form the effective detection limit decreases, also, a desktop unit can be more effective that the small handheld XRF. I'd be surprised if the lower detection limit for gold was going to be lower than 5 ppm. It could be really good for a series of other elements such as copper, silver, or nickel.
