Specific Gravity: Mineral Properties

Specific Gravity, also known as SG, is a measurement that determines the density of minerals.Two minerals may be the same size, but their weight may be very different. The specific gravity of a mineral determines how heavy it is by its relative weight to water.

Deep-Ocean Mineral Deposits: Metal Resources and …

Beyond the first-order assumption that deep-ocean mineral resources are likely to be proportionate to the area of the seafloor (Hannington et al. 2011), we know that specific geodynamic and oceanographic settings control the types of mineral deposits that form and that they influence deposit spatial density, size, form and geochemistry (Figs. 1 ...

LKAB Minerals

LKAB and Boliden collaborate to recycle mining waste and create circular products The leading Swedish mining companies LKAB and Boliden have signed an agreement and will begin working together to investigate the possibility of extracting pyrite concentrate from mining waste at the Boliden Aitik mine, which LKAB will subsequently process into fossil-free sulphuric acid.


Heavy liquids of suitable density are used, so that those minerals lighter than the liquid float, while those denser than it sink. The process offers some advantages over other grav ity processes.
