· (2) Concentrate grade. The general rule is that the concentrate grade is higher when ore flotation is carried out in a leaner slurry, while the concentrate grade is reduced when it is floated in a thicker slurry. (3) The dosage of the agent. The flotation agent should maintain a certain mass fraction in the pulp to have a good flotation effect.

· Dahlonega was the center of a huge gold rush in the 1820s. There is still a lot of gold to be had in the Dahlonega area. We didn't have time on this trip to go prospecting out on the creeks. However, there are several active gold mines in the area, and some of them will sell you their crushed and concentrated ore (at fairly reasonable prices).

Concentrates are the raw material for all copper smelters, which by processing it obtain an impure form of metallic copper, anode or blister copper, which is later used to produce high purity refined copper. The production of concentrates implies the crushing and later milling of the ore down to a particle size allows releasing copper by flotation.

So as you are crushing, stop and screen your material, removing any free gold which has already separated from the rock during your crushing that won't go through your screen with your fingers. The coarser rock that won't go through your screen can then be returned to the crusher for further work to break it down, and the fines won't get in the way.
