Bulk primary sample preparation

User Rating:  / 0
Published Date Written by Sara Prins


We embarked on realising a long-term wish in 2016, and now finally have in place our dream: a comprehensive bulk primary sample preparation facility.

Sample preparation is the most important step in any analysis, hence it is critical that any bulk sample is treated in the best way to not only maintain its integrity but also to ensure that the final few grams that is used for analysis inside the laboratory is a representative sample of the bulk that was received.

Our new facility has capacity to handle anything from small samples to both bulk numbers of samples or bulk weight samples. We offer ample drying facilities, access to a number of crushers, splitters and pulverisers, as well as compositing of samples. At each stage our dedicated and competent team follow international best practices and standards, including recording the mass of the sample through every stage of preparation.

Finally, we also offer on-site storage of your bulk sample reserve for 3 months free of charge if it is submitted to the laboratory for analysis.sara

Need help with waste analysis?

Recently new legislation was introduced which has placed more focus on ensuring stockpiles, mine dumps and general waste management are environmentally complaint.

With effect from 24 July 2015, the establishment and reclamation of mine dumps and stockpiles of mining waste from or incidental to a mining operation, must comply with new regulations regarding the planning and management of residue stock piles and residue deposits from a prospecting, mining, exploration or production operation (Mining Residue Regulations) published under the National Environmental Management: Waste Act 59 of 2008 (NEM: WA).

The implications of the new regulations furthermore are that stockpiles must comply with landfill requirements and also comply with the National Norms and Standards for the Assessment of Waste for Landfill Disposal, 2013; and National Norms and Standards for Disposal of Waste to Landfill, 201.

UIS Analytical Services is set up to provide you with a one-stop service for a fully Waste Act compliant analysis to determine Total Concentrations and Total Leach Concentrations on your samples.

Ultimate analysis of coal samples

User Rating:  / 1
Published Date Written by Sara Prins

Chemical composition of the coal is defined in terms of its proximate and ultimate (elemental) analyses.

The parameters of proximate analysis are moisture, volatile matter, ash, and fixed carbon. Elemental or ultimate analysis encompasses the quantitative determination of carbon, hydrogen, nitrogen, sulfur and oxygen within the coal.

 UIS Analytical Services can assist you with your proximate and ultimate analysis needs.

The calorific value Q of coal [kJ/kg] is the heat liberated by its complete combustion with oxygen. Q is a complex function of the elemental composition of the coal. Q can be determined experimentally using calorimeters. Dulong suggests the following approximate formula for Q when the oxygen content is less than 10%:

Q = 337C + 1442(H - O/8) + 93S,

where C is the mass percent of carbon, H is the mass percent of hydrogen, O is the mass percent of oxygen, and S is the mass percent of sulfur in the coal. With these constants, Q is given in kilojoules per kilogram.
