Boa tarde a todos!

"valioso e incômodo" me pareceu estranho.

CONTEXTO:


This further implies that, from an understanding of the reactions between particularly the silicate gangue minerals and sulfuric acid, it is possible to make predictions about the likely acid consumption of the ore under various conditions of irrigation acid strength, and from that can follow predictions about the precipitates that are likely to form inside the heap, as well as the (both valuable and nuisance) soluble species that are likely to report to the pregnant leach liquor feeding the downstream recovery steps. Such predictions can already start to be made during the earliest phase of a project, when only a limited amount of drill core sample may be available, based on a knowledge of the gangue mineralogy, coupled to geochemical database information and modelling
software.
