The 2019 GA meeting which took place on Wednesday 8 May 2019 in Madrid, Spain was a resounding success. Hosted by FerroGlobe, the meeting which lasted 4 hours saw several deliberations related to the consortium governace, dossier updates and classification & labelling. Some key decisions taken by way of vote are as follows:
Some highlights:
- Executive Committee: A new Chairmanand a new 2nd Vice Chairman were appointed, meanwhile the 1st Vice Chiarman was maintained to enure continuity
- Dossier updates: Reveal changes in classification and labelling if compared to the 2010 submitted dossiers
- Approval of the 2018 workplan and budget
- Brexit and data: Mara will continue to support REACH registration inside and outside the EU (UK REACH inclusive) but at a charge yet to be determined
DETERMINATION OF WATER SOLUBILITY/ SiMn slag (Silicomanganese slag)/ OECD 440/2008/ GLP
The water solubility of the test material, expressed as the total amount of total metal dissolved, has been determined using the flask method, Method A6 Water Solubility of Commission Regulation (EC) No 440/2008 of 30 May 2008 and Method 105 of the OECD Guidelines for Testing of Chemicals, 27 July 1995.
The results can be seen in the table below:
| Metal dissolved | Concentration range (g/l) |
| Magnesium | ≤6.83 x 10-4 |
| Aluminium | ≤9.45 x 10-4 |
| Silicon | ≤2.26 x 10-4 |
| Potassium | ≤3.60 x 10-4 |
| Calcium | ≤2.64 x 10-4 |
| Manganese | ≤3.27 x 10-4 |
| Barium | ≤2.13 x 10-4 |
