In this work, two different samples (samples 1 and 2) which have different combinations of aluminum silicate are used by present reagent to examine disturbing factors of flotation (DTAL, SFL, and MIBC), which is used for research on changes of current planned reagents.
1- In desilication of disturbing factors of flotation, from among the diasporic bauxite ore whose pH range is between 6 and 7, 1/4 ammonium salts (DTAL) is the best choice as compared to the dodecylamine and Cetyl trimethylammonium bromide.
3- In both samples 1 and 2, the use of new reagents (MIBC, SFL, DTAL) shows us the best desilication fluctuations and bauxite concentrate (A/S> 10, Al2O3 (RGP)> 0.86).

Stuart Bright, Operations Manager of DNV GLs DTAL, said This is an exciting development for DNV GL we are opening a unique laboratory for the independent assurance and testing of smart energy and cyber security products in one of the UKs award winning Smart Cities.
The DTAL is gearing up to respond to this challenge and last year, DNV GL recruited best-in-class security experts.
I am pleased that DTAL is at the heart of providing this assurance and is therefore at the core of DNV GLs vision for a safe and sustainable future, noted Prajeev Rasiah, Executive Vice President for Northern Europe, Middle East & Africa (NEMEA), DNV GL Energy.
