“…3 A) a CAGR das patentes (TRL4-5) é cerca de três vezes maior do que a dos artigos (TRL3), ou seja, está havendo aceleração da maturidade tecnológica, o que pode ser devido ao aumento da preocupação com o meio ambiente e à redução dos impactos dos fluidos EOR. No aso do Brasil, pode ser também efeito da Lei da Inovação de 2004 (Brasil, 2004) que regulamentou o patenteamento nas organizações acadêmicas governamentais e suas parcerias com empresa e demais setores da sociedade. A produção de petróleo continua praticamente estável, com CAGR de cerca de 1%, indicando a constância global média de seus mercados no período inicial.…”

Goma xantana e HPAM são polímeros de baixo impacto ambiental utilizados em formulações de fluidos aquosos para EOR, sendo essencial monitorar as novas tecnologias, especialmente em ambientes salinos como o Pré-Salt. Foram mapeados e analisados 881 artigos (TRL3) na base Scopus e 469 patentes (TRL 4-5) na base worldwide do EPO com Orbit ®, utilizando palavras chave e IPCs. O crescimento exponencial recente da evolução anual acumulada sugere um desafio tecnológico. A China domina os TRL3-5, por sua estratégia nacional. Devido à sua resistência à degradação microbiana e baixo custo, o uso de HPAM é cinco vezes maior em patentes e três vezes maior em artigos do que o de xantana. Recentemente a xantana passou a ter mais patentes do que artigos dada sua estabilidade térmica e produção biotecnológica, favoráveis à salinidade aquosa. A taxa de crescimento anual composto (CAGR) se estabilizou recentemente, isto pode ser consequência da pandemia da indicando um desafio tecnológico.

“…To work around this situation, reagents have been developed so that flotation presents selectivity. Studies such as those performed by Souza et al (2014), Oliveira (2007), Carneiro (2018), Carneiro et al (2021), Guimarães et al (2004), Martins et al (2019), Oliveira et al (2019), among many others presented in the literature, bring fundamental studies, in addition to analyzing the performance of collectors and depressants. They show this scientific initiative in the search for optimal conditions in phosphate ore flotation operations.…”

To meet the growing demand for fertilizers, strategic in food production, efficient ways of concentrating its main raw material, phosphate rock, are essential. Moreover, when the phosphate ore has carbonated gangue, such as the mineral deposit of Araxá-MG, there is a selectivity difficulty in separating the mineral species, impairing the flotation performance. The search for reagents that present selectivity, low cost and high availability has been the subject of research. Thus, the objective of this work was to evaluate a depressor reagent (starch residue) and collector reagents (Amazon oil from Andiroba and Hydrocol) in the flotation of phosphate ore. For this, the previously characterized ore was subjected to flotation tests in a bench mechanical cell. The independent variables evaluated were type of collector, collector dosage and depressant dosage, with two levels and central point, according to the factorial design. The results revealed that Hydrocol, at minimum dosage levels, provided concentrates with higher P2O5 content (17.78%) and metallurgical recovery (66.29%). However, the Amazonian oil, at maximum dosage levels, presented similar contents, but with lower recovery values, indicating that it is a selective reagent and showing promise, considering that the oil is a residue of industrial processes.

The search for environmentally friendly reagents with high efficiency, high selectivity, and low cost has intensified in the mining sector in recent years. The use of depressants from alternative and renewable sources is an option to be considered. Thus, the purpose of this study was to evaluate the use of residual potato starch pulp (RPSP) generated by the food industry as a depressant in phosphate ore flotation by comparing its performance with that of commercial, waxy corn starch (CWCS), rich in amylopectin. To this end, eight flotation tests were performed in duplicate using the Denver mechanical cell. The results showed significant variations for flotation in the collector dosage and starch-type parameters. The increase from 150 to 350 g/t in the collector dosage promoted an approximately 18% increase in metallurgical recovery using 500 g/t of RPSP starch (an increase from 73.09% to 86.16%). The response optimization statistical tool showed that RPSP and collector dosages should be 500 and 226.77 g/t, respectively, to maximize the P2O5 content and metallurgical recovery. These results suggest that it is feasible to use RPSP in phosphate ore flotation, opening new fields of investigation regarding the use of more accessible and economical depressants.
