Alum is located in Tulcea, the biggest city on the Danube River, before the Black Sea. In Romania, Tulcea with 100,000 people are referred to as The gateway to Danube Delta, The plant has processed more than 17 different types of bauxites from Greece, Guinea, Australia, India, Sardinia, Yugoslavia, Brazil and Guyana, in different mineralogical combination gibbsitic, boehmitic and diasporic. Processing in parallel two bauxites diasporic and gibbsitic, or diasporic and boehmitic, or boehmitic and gibbsitic.

Sweetening process applied in the flashing process in the digestion process. Increases digestion productivity by 5 %..

Starting 2010 Alum use only Sierra Leone bauxite having good results in plant operation and specific consumptions.

Alumina SpecificationThe alpha () alumina content of the metallurgical grade alumina is between from 2 to 5 %, when is required.L. O. I. : 1 % max.Particle size distribution: < 45 m - 4 6 % > 150 m - < 10 %Angle of repose - 32 36o Bulk density - 1.00 1.10 gr/cm3BET - 60 85 m2/g- SiO2 - max. 0.015 %- Fe2O3 - max. 0.015 % Alums main strategic objectives are:- increasing the production to 600,000 tpy modernization of the production system reduction of the production costs by controlling the specific consumption for raw materials, materials, natural gas and electricity reaching the bench market technological level achieving the European of the environmental norms

The 2006 - 2010 investments program includes the following sections:

Production increase to 600,000 tpyIncreasing the Grinding capacityPedesilicationIncreasing the static kiln production capacityModernization of filtration systemsImproving the equipments capacityApplying new technologiesRed mud pond Modernization Costs reduction -Modernization of actual equipment - digestion and precipitation batteries, settlers, filters (Control filtration and White Filtration), evaporation batteries, grinding mills, steam boilers, etc.Implementation of different process technologies double digestion, processing of three grades of bauxites Replacing inefficient equipments rotary calciner, pumps, heat exchangers, burning systems, cooling towers, Horizontal filter (BOKELA) at White Filtration Environmental- Burning system conversion to use natural gas for boiler C2Ap no 2 Red mud pond modernization Cooling tower for a better water consumption Bag filters on static kiln

SC ALUM SA promote the policy of developement, on the preventing, reducing and polution control principles by using the best available technics for the activities

To acomplish the Environmental Protection Policy, SC Alum SA applying the following concepts: Conformation at the actual environmental legislation and at the future legislation evolution regarding Alums activities Improving continuosly of its performances regarding environmental protection and preventing polution factors by its activities Trening all personel for environmental isues and encouraging to have an activ atitude as natures friends

Reducing and minimization of emisions and residue by applying the best techniques available. Working all the time together with the environmental protection authoritys and with the local citizens for implementing and applying continuosly of the environmental policy for monitoring the obtained results. Periodicaly, the top plant management are analizing the results and the effects of adopted environmental policy for improving the results.
