Dry gravity separations can be made more efficient by separately processing groups of smaller particle size ranges. When the price of gold increased from 300 to 1,500 per ounce, the average grades of gold ores mined and processed dropped from 5 grams per ton down to the 1 gram per ton range.
The object of gravity concentration is the separation of the heavy valuable mineral from the light worthless gangue. Complications are often introduced by the fact that various base minerals must be separated from one another, an ore being subdivided into several products. Most gold ores, however, only require separation into two parts—the "concentrates," in which the precious metal is ...
In gold plants, for example, a number of gravity devices, old and new, are being used to recover relatively coarse gold. Over the past few years gravity separators that take advantage of differential specific gravities in a highgradient centrifugal force field (, Knelson and Falcon separators) have been used successfully for gold.

Placer mining is very popular because: 1) of the low cost of this type of mining and 2) the fact that most of the gold can be recovered using lowtechnology (gravity) recovery methods. Open pit mining is popular for many of the same reasons.
Placer Gold Deposit and Mining Beneficiation JXSC. The beneficiation of placer gold ore is based on the difference in physical properties of minerals, such as the difference in particle size, shape and specific gravity, the gravity separation is the main method of placer alluvial gold beneficiation processing.

The concentration effect was being used to advantage, with a bleed stream from the tertiary cyclon e underflow providing a high feed grade to the gravity circuit. The concentration effect however, was also a major disadvantage. The high circulating load for gold was contributing to the flattening of the free gold .

gravity highs, whereas deposits of lowdensity halite, weathered kimberlite, and diatomaceous earth yield gravity lows. The gravity method also enables a prediction of the total anomalous mass (ore tonnage) responsible for an anomaly. Gravity and magnetic (discussed below) methods detect only lateral contrasts in density or magnetization ...
Spiral Chute / Spiral SeparatorSpiral chutes are gravity concentrators and separate minerals by minerals different specific gravity, according to their relative movement in response to gravity,centrifugal force and other forces in the fluid medium. It has extremely good performance and effects in processing placer minerals from beach, riverside, seashore and stream.

Operating a centrifuge takes skill as it must be tuned to the material it is processing. This is accomplished by adjusting feed grain size, rate of feed, rotation velocity, and cycle duration. Centrifuges can be more effective at concentrating gold than other methods of gravity concentration but are generally more expensive.
A typical application for a Falcon SB Gravity Concentrator is recovering liberated precious metals (Au, Ag, Pt, etc.) within a grinding circuit. Outside grinding circuits, Falcon SB Gravity Concentrators are also used for precious metal separation from aggregate or placer deposits.. Falcon SB Gravity Concentrators are known as "SemiBatch" Gravity Concentrators because they continually ...
