| MINERAL LIBERATION ANALYSES (MLA) |
|---|
Samples of processed ore minerals should be crushed and separated to particle size fractions by sieving in specific sieve openings.
Largest particle size in sieve fractions should be 1.000 micron and less. Sieve openings for sieve fractions under 100 micron should be kept as narrow as possible (such as (-100+75 micron, -75+53 micron, -53+38 micron, -38+15 micron)
As flocculation tendency of sieve fractions with particle size under 38 micron is high, very fine particle sieve fractions should be prepared with wet elimination method without causing flocculation during sample preparation and sent.
The samples should be chosen to represent the area they have been taken and the target study the best.
The Samples should have “Sample Tags” fulfilled by the entity that request the Mineral Liberation Analysis. Each tag should have sample mark, sample type and necessary information for the requested analysis legibly. The sample mark in the tag should be stated in the Analysis/Test Application Form.
The same sample mark should not be used for different samples. Otherwise, the samples will not be processed.
In case of multiple analyses/tests for one sample, sample size should be increased depending on the analysis type and number.
The samples should be sent in a clean, transparent nylon bag in a resistant cloth bag.

Modal (Quantitative) Mineralogical Analysis (In samples for technological works) |
This analysis is performed only for the samples of technology work. Quantitative modal mineralogical compound of each sample is given at the end of the analysis. A preliminary study is necessary to determine mineralogical compound, ore content, particle size, sieve fractions of the sample and MLA analysis to be performed. Maximum 8 (eight) samples are accepted with a single Analysis/Test Application Form. |
Contacting with related Unit via Sample Acceptance Unit and getting an appointment is necessary before the application. Analysis period is determined as per the time schedule prepared following acceptance of the application and this period is notified to the other side. |
Minimum 10 g and maximum 100 g ore sample that has been separated to different sieve fractions by sieving. |

Standard MLA (Mineral Liberation Analysis) (In samples for technological studies) |
This analysis is performed only for the samples of technological studies. As a result of the analysis; database file consisting of quantitative modal mineralogical composition, calculated element content, elemental dispersion, particle size distribution, mineral size distribution, mineral associations, liberation degree, interlock status, particle density and particle shape parameters of each sample is saved and given in CD medium. A preliminary study is necessary to determine mineralogical composition, ore content, particle size, sieve fractions of the sample and MLA analysis to be performed. Maximum 8 (eight) samples are accepted with a single Analysis/Test Application Form.
