Simply put, pre-concentration drastically reduces the ore mass that reports to intensive downstream processing By using gravity to recover mineral-bearing particles into a much smaller volume, significant savings in energy and operational expenses are achieved
Only a very small fraction of the diamond ore consists of actual diamonds The ore is crushed, during which care is required not to destroy larger diamonds, and then sorted by density Today, diamonds are located in the diamond-rich density fraction with the help of X-ray fluorescence, after which

Jun 26, 2015· The Specific Gravity (SG) of a substance is a measure of its density It is expressed as the ratio of the weight of a given volume of the substance compared to the weight of an equal volume of a reference substance – usually water An alternative term sometimes used is: ,
This is a Diamond Processing Chart as it was done in the 1950s World demand and production of diamond both for gem and industrial purposes has increased nearly five-fold during the past 25 years Improved mining and recovery methods together with the discovery and development of new fields has enabled mining operations to fill the growing demands
Examples are the pre-concentration of diamond ores or metalliferous ores like nickel, copper and cobalt Dense medium separation is also used to upgrade the material to meet different market specifications, for example in coal and iron ore applications A typical dense medium separation process for a diamond application is shown in Figure 1
Since specific gravity is relative to the weight of an object in air and its weight in water, it is a ratio and isn't expressed in units (such as kg/m³) For instance, the SG of Diamond = 352 (whereas the density of Diamond = 352 g/cm³) In gemology, specific gravity is, usually, determined through an apparatus based on Archimedes' Principle
There are many methods of separation (concentration) of minerals: 1) Gravity separation There are more than 12 types of gravity separation of minerals It is used for the extraction of gold, coal, cassiterite, wolframite, rare earth mineral, niobium, zirconium, uranium minerals, and others Read more 2) Magnetic separation There are more than 14 types of magnetic separation of minerals
Both methods are in actual fact used for bulk material reduction and require a further process for the final diamond recovery These systems are based on the property of diamonds having a much higher specific gravity (density) of ~352 g/cm3 compared to most of the other minerals that make up material in which diamonds are found
Density and Specific Gravity defined Density is expressed in terms of mass per unit volume The density of water, often used for comparisons, can be expressed as 10 g/cm3 or 1,000 kg/m3 Mineralogists often use the unit-less measurements of specific gravity, which is the density of a mineral relative to that of an equivalent volume of water A
Gravity Concentration is widely used in the processing of coal, nonferrous metals, precious metals, precious metal ore, also used for asbestos, diamond and other non-metallic mineral processing In order to enhance the separation efficiency of gold in Gravity Concentration also uses centrifugal force field spiral chute, centrifuges, cyclones .
Definitions of Unrefined and Refined Minerals Antimony Main pre-concentration process: milling and screening The mining of barite ore serves as a source of two significant products: barite and Gravity concentration and flotation are also used in the concentrating of iron or 61%
The specific gravity of all other materials are compared to water as a fraction heavier or lighter density For example, ammonium nitrate has a specific gravity (sg) of 073 while dry ammonium sulphate has a sg of 113 (1130 kilograms/cubic metre) (see table below)
Specific Gravity Table (Typical) for Metals, Minerals and Ceramics from READE
The 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, beryllium has a specific gravity (sg) of 184 (1840 kg/m³) As specific gravity is just a comparison, it can be applied across any units
Heavy Media Gravity Separation Heavy media gravity separation involves using a mixture of fine media material, such as magnetite (SG 51) or ferrosilicon (SG 68), suspended in a slurry of water, to produce a media slurry with a specific gravity that will allow low density material(s) to float, and other high density material(s) to sink
