BIOLIXIVIAÇÃO: UMA AVALIAÇÃO DAS INOVAÇÕES TECNOLÓGICAS NA BIOMINERAÇÃO DE MINERAIS SULFETADOS NO PERÍODO DE 1991 A 2015
BIOLEACHING: AN EVALUATION OF TECHNOLOGICAL INNOVATIONS ON THE SULPHIDE MINERALS IN THE PERIOD OF 1991 TO 2015
Giese, Ellen Cristine
Resumo
O desenvolvimento de inovações tecnológicas nos processos de biolixiviação tem sido constante, principalmente, pelo fato dos processos biohidrometalúrgicos oferecerem vantagens frente às plantas convencionais, v. g., a diminuição dos custos operacionais e de geração de resíduos. O objetivo deste trabalho foi avaliar o perfil das competências tecnológicas relacionadas à este processo através do estudo das patentes depositadas na base de dados da Organização Mundial de Propriedade Intelectual (OMPI) nos últimos 25 anos. Observou-se que, entre os anos de 1991 e 2015, cerca de 328 patentes foram depositadas na Patentscope, destacando-se a China e EUA que somados detém igualmente 44% dos registros. A partir dos resultados obtidos nesta pesquisa, foi traçado um paralelo entre os depósitos de patentes e a economia mineral. A análise dos dados obtidos permitiu descrever as tecnologias preferencialmente protegidas dos processos de biolixiviação.

Abstract
The development of technological innovations in bioleaching has been constant, especially, the use of these biohydrometallurgical processes offer advantages over conventional plants, such as lower operating costs and waste generation. The objective of this study was to evaluate the potential of technological competence related to this process through the analysis of patents in the database of the World Intellectual Property Organization (WIPO) in the last 25 years. It was observed that between the years 1991 and 2015, about 328 patents were filed in Patenstcope, especially China and USA which added also holds 44% of the documents. From obtained results, it has drawn a parallel between the patent deposits and the mineral economy. The analysis of the data allowed describing the technologies protected preferably of bioleaching processes.
