Scanning Electron Microscopy – Energy Dispersive Spectroscopy
 
 
 
The purpose of this analysis
 
Analysis SEM-EDS used to find out what elements and minerals are in rocks as well as where the element is located visuallyThis analysis helps to understand potential causes of processing problems before moving on to further tests.
 
 
 
What SEM-EDS answers
 
 
 
SEM-EDS helps answer questions such as:
 
 
 
 
What elements are is in the stone
 
 
 
 
Is it gold or another metal? associated with certain minerals
 
 
 
 
Are there any problematic elements such as S, As, Cu, or carbon
 
 
 
 
Why a material potentially difficult to process
 
 
 
 
 
What is analyzed
 
 
 
 
Identification of major elements and minerals
 
 
 
 
The visual relationship between metals and their binding minerals
 
 
 
 
Early indications process-disrupting minerals
 
 
 
 
 
SEM-EDS is qualitative to semi-quantitative, not a precision content analysis)
 
 
 
How the analysis is carried out
 
 
 
 
Samples were polished and analyzed using Scanning Electron Microscope (SEM)
 
 
 
 
System EDS used to identify elements at a particular point or area
 
 
 
 
The results are in the form of images and element maps, not a detailed level figure
 
 
 
 
 
Operational information
 
 
 
 
Number of samples: usually ≥ 100 grams
 (final requirements depend on grain size and material condition)
 
 
 
 
Duration of work: ± 5–10 business days
 
 
 
 
Terms and conditions apply (the type of material and the purpose of the analysis affect the scope)
 
 
 
 
 
Cost & sample delivery
 
 
 
 
The analysis fee does not include the cost of sending the sample to us.
 
 
 
 
All costs and risks during shipping are borne by sender's responsibility
 
 
 
 
 
Value added services
 
SEM-EDS not just looking at pictures of minerals.
 
 
 
Results are accompanied by practical interpretation by mineral processing expert, to help you understand:
 
 
 
 
What is the material potentially problematic during processing
 
 
 
 
What elements or minerals are needs further attention
 
 
 
 
Is it necessary? advanced analysis such as SEM-MLA or metallurgical testing
 
 
 
 
 
When to choose SEM-EDS
 
 
 
 
If you want understand the material character from the start
 
 
 
 
If the processing results not as expected and the cause is not clear
 
 
 
 
If you want determine appropriate further analysis
 
 
 
 
 
SEM-EDS is not used for
 
 
 
 
Determine the level or economic value
 
 
 
 
Determining the optimal grind size
 
 
 
 
Replaces SEM-MLA or metallurgical testing
 
 
 
 
 
Summary
 
SEM-EDS shows what elements and minerals are in the rock as well as potential processing problems, without determining grade or recovery.
