Mineral Specific Gravity Now that we have determined the density of our sample it is a piece of cake to determine its specific gravity Recall that specific gravity is simply the ratio of the Shaking tables are often chosen by smaller cost conscious or chemical sensitive gold mines for production of smeltable gold from gravity concentrates where they are located downstream of FL Knelson Concentrators and GoldKachas Shaking tables are also often used for primary concentration of gold and other heavy minerals from or

Specific gravity Definition A mineral s specific gravity is the ratio of its mass to the mass of an equal volume of water For example magnetite has a specific gravity value of 52 meaning 1cm 3 of magnetite will be 52 times as heavy as 1cm 3 of water Test Although this property can be precisely measured it is often tested by simply hefting the specimen in the handHolman are world leading suppliers of gravity separation tables shaking tables to the mining minerals and recycling industri Our products are used for alluvial gold mineral sands tin tantalum and recycling of copper cable and WEEE waste

A history of gravity separation at Richards Bay Minerals result in blockage of the mouth organ splitters and inserts affecting the even distribution of slurry feed to the separation surfac Cleaning the aforementioned splitters and slots was a tedious chore not looked forward to by the operating crewsregularly checking the specific gravity of a large mineral fragment of known specific gravity such as pure quartz If apparent specific gravities begin to decrease measurably over time then the ethanol should be replaced Finally when repeating a series of measurements it is essential that the sample be allowed to dry completely
