### Mineral processing Concentration | Britannica

Gravity methods use the difference in the density of minerals as the concentrating agent. In heavy-media separation (also called sink-and-float separation), the medium used is a suspension in water of a finely ground heavy mineral (such as magnetite or arsenopyrite) or technical product (such as ferrosilicon).

### Concentration determination by means of density

A limited concentration range is covered, so the sample has to be diluted accordingly. Further, a special setup depending on each individual sample is needed. Another drawback of titration is the use of aggressive chemicals and the need of costly consumables. These points make this method very time-consuming and not user-friendly.

### Artisanal and Small-Scale Gold Mining Without Mercury

Panning offers miners a low cost method of gravity concentration but it requires time and skill to be effective. One of the major drawbacks to panning is that miners must pan small amounts of concentrate. Therefore, panning is often done after other methods of gravity concentration such as sluicing have completed. Sluicing. Sluices use water to wash ore or alluvium down a series of angled

g is the acceleration due to gravity. Analytical data are based on mass rather than weight. A balance is used to compare the mass of an object with the mass of one or more standard masses. g affects both unknown and known equally, hence, the mass of the object is identical to the standard masses with which it is compared. w mg. 4A-3 The Mole The mole (abbreviated mol) is the SI unit for
