Specific Gravity and Bulk Density SGS South Africa

SGS is a leader in providing accurate, bankable results from a wide range of mineral tests. This includes the determination of the specific gravity (SG) and bulk density (BD) of rocks, ores and aggregates using the pycnometer and water and air method or wax method if required. These tests are conducted regularly in many SGS laboratories.

South African opencast coal mines spore density and ...

2020-7-1  stockpiles of South African coal mines differ from those of unmined soils. Furthermore, it is unknown if the viability of AMF spores is impaired in these stockpiles. This study set out to test the hypothesis that AMF spore density and viability differ between undisturbed soils and soil stockpiles of opencast coal mines in South Africa.

Characterization of the coal resources of South Africa

2009-8-26  Estimates for South Africa’s coal recoverable reserves made in 1999range from nine to 59 billion tons; latest estimates by the MineralsBureau suggest that 33 billion tons is a more likely figure. As muchas 70% of that coal is located in the Waterberg, Witbank, andHighveld coalfields, as well as lesser amounts in the Ermelo, FreeState and Springbok Flats coalfields. However, the Witbank andHighveld coalfields are approaching exhaustion (estimated 9 billiontons of recoverable coal remaining in each), while the coal qualityor mining conditions in the Waterberg, Free State and SpringbokFlats coalfields are significant barriers to immediate, conventionalexploitation.

Review of the South African Coal Mining Industry

In 2012 South Africa's ROM coal production amounted to 330Mt. The 117 South African collieries produced 258.6Mt of saleable coal. It exported 76Mt valued at R52.227 billion at the average price of R687/t and used for the inland market, 184.1Mt valued at R43.921 billion at an average price of R238/t, ranging from R103/t (steam coal, mainly for Eskom) to R2 154/t (coking coal). 75.6Mt were discarded.

ISO 23499:2013(en), Coal ? Determination of bulk

This International Standard provides description of a cone procedure for determining an uncompacted bulk density of crushed coal less than 37 mm in size, such as is charged into coke ovens. It focuses on the uncompacted bulk density of coal resulting from flowing the material into a measuring container (box) in the absence of compacting forces.
