The specific gravity of the feed was 1.116 and the underflow discharged at a specific gravity of 1.660 under normal conditions. Most of the ore is mined by underground mining, and gold is extracted from free milling ores by cyanidation using carbon-in-pulp method. pH, temperature, pulp density, iron concentration, and bacterial

MoreThe Marcy Pulp Density Scale correlates the specific gravity of the ore with the percent solids of the pulp. This information is displayed on a circular scale for several specific gravities by use of a simple weigh scale. The simplicity of the scale along with its many applications have made the Marcy Pulp Density Scale a common feature at concentrators throughout the world.

MoreAs used in these formulas the specific gravity of the ore is obtained simply by weighing a liter of mill pulp, then drying and weighing the ore.With these two weights formula 2 may be used to obtain k, and then formula 1 to convert to s, the specific gravity.A volumetric flask of one liter capacity provides the necessary accuracy.

Moredetermination of specific gravity of iron ore. Specific gravity is a unitless measure because it is derived from the density of the mineral divided by the density of water and thus all units cancel However since water s density equals 1 gram per cubic centimeter at specific conditions then a mineral s specific gravity would also correspond to a mineral s density as expressed in grams

MoreThe use of specific gravity in determining the grade of iron ore is not a new procedure. Eckel (1910, p. 38) pointed out the approxi mate correlation between specific gravity of the Alabama iron ores and their iron content. Feld, Coe, and Coghill (1946) devised a rapid specific-gravity method for estimating the iron content of powdered

MoreAs specific gravity is just a comparison, it can be applied across any units. The density of pure water is also 62.4 lbs/cu.ft (pounds per cubic foot) and if we know that ammonium nitrate has a sg of 0.73 then we can calculate that its density is 0.73 x 62.4 = 45.552 lbs/cu.ft.

MoreThe specific gravity of all other materials are compared to water as a fraction heavier or fraction lighter density, no matter how small or large the fraction is. For example, ammonium nitrate has a specific gravity (sg) of 0.73 while dry ammonium sulphate has a sg of 1.13 (1130 kilograms/cubic meter).

MoreApr 03, 2014· The specific gravity of iron bearing minerals is usually higher than the specific gravity of gangue materials. Effectiveness efficiency of the gravity separation depends largely on to proper crushing and sizing of the ore so as to ensure a proper size feed to the gravity separation equipment and also removal of slime from the equipment.
