Terminologia do ciclo de produção do alumínio: bauxita, alumina e alumínio

Abstract

This study aimed to describe and present, in dictionary form, with a printed and an other electronics version, the technical language of the primary aluminum production cycle in Pará State, distributed in three activities: bauxite mining, alumina refining and metallurgy of aluminum. Therefore, we investigated the language of the three largest companies that develop these activities, respectively the Mineração Rio do Norte S.A. (MRN), HYDRO ALUNORTE and the Alumínio Brasileiro S.A. (ALBRAS). The research was based theoretically and methodologically in two terminological theoretical currents - the Socioterminology and Communicative Theory of Terminology. The data collection was taken from a corpus of 173 specialized texts and 18 institutional DVDs distributed according to these three activities developed by the companies. With this collection work, we extract technical terms, definitions and contexts of occurrence. These data were introduced into a computer program called Lexique Pro, which automatically organized the macro and microstructure of the dictionary. After a provisional version of the dictionary, we check the information contained in the dictionary with some experts of the activities involved to verify if the informations were correct. The final version of the dictionary has 1,110 terms that represent a broad universe of current technical language of the aluminum production cycle, of which 362 are related to the mining of bauxite, 228 relate to the refining of alumina and 693 relate to the metallurgy of aluminum. As for the grammatical categories, the dictionary has 564 masculine nouns, 516 feminine nouns, 22 verbs and 8 adjectives. Altogether, 97% of the words are nouns. The dictionary presents, according to the variationist model developed by Faulstich (2010), 214 formal variants (concurrent variants), 164 synonyms (coocorrentes variants) and 50 loanwords (competitive variants). The Dictionary that we present aims to systematize the technical language of these three main activities of the aluminum production cycle. In this perspective, the main purpose of this work was to produce a technical dictionary that favour communication between interested by this activity, between the public object of the research, researchers, teachers and students.
