O problema da extracção do alumínio a partir dos sienitos nefelínicos

Some countries producers of the aluminium, attempt to use other ores which, in the future, will gradually substitute the bauxite as a raw material. Portugal possesses an nephelinic syenite massif which may be utilized for this purpose because the nepheline offers some advantages above other poor ores which are being essayed now. By laboratorial processes, the author puts forward those advantages and calls the attention for the necessity of to accomplish essays about the nepheline (by the acid's method) and realize petrographic's detailed reconnaissances of the Monchique syenitic massif.

Reynaers Aluminium commercial & marketing plan to Angola

The current paper seeks to fulfill an internationalization action plan for Reynaers Aluminium Portugal (RAP) to address the Angolan construction market. Strong market opportunities have been spotted, namely: an increasingly well-succeeded presence of Reynaers’ customers; Reynaers portfolio responsive to an increasingly quality demanding Angolan market; strong support from the multinational chain. Aligned with a constant threat from the Portuguese economy RAP seeks to establish a stronger presence in Angola. Indeed the company has been approaching this market since 2008, resulting in the identification of key players and synergies spotted. For this purpose, the aim is to develop a Commercial and Marketing Plan while taking into consideration the results of the previous company interventions that reflect this market’s DNA.
