Whenever gold carriers are targeted, the benefits are generally higher, as is the cost of the gravity circuit. These applications include preconcentration (although this is more commonly achieved with flotation; see Chapter 20) and scavenging of gold carriers.A discussion on the use of gravity instead of flotation for preconcentration is included in …

The graph provides some interesting insight on the effective use of gravity concentration for gold recovery. Key points to note from Figure 1 are: • Gold recovery rises very rapidly (steep slope) up to treating about 10% of the cyclone underflow • A transition stage occurs between ~10-25% where is there is a diminishing rate of recovery

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.

The Specific Gravity Test (used to calculate the gold content of gold nuggets that contain a mixture of gold and other materials) In this example of the specific gravity test, we use gold mixed with quartz. Simply put, the formula is 3.1 x the weight in water, minus 1.9 x the weight in air: Wet nugget weighs 74.5 grams x 3.1 = 230.95

To calculate the specific gravity of a substance, follow these easy steps: Use a scale to measure the mass of that volume: m. Calculate the density of the substance with the ratio: ρ = m/V. Choose your reference substance and calculate its density: ρr = mr/Vr. Calculate the ratio between the densities: sg =ρ/ρr.
