Application of a Rapid and Simple UV-spectrophotometric method for the study of desorption of esterquat collectors in Tailings-Seawater Systems
Ibragimova, Olga; Kleiv, Rolf Arne (Journal article; Peer reviewed, 2018)The growing demand for mineral resources followed by the steady increase in mining activity result in the need for the disposal of large amount of tailings. Submarine tailings placements (STPs) is a viable option to ... -
Development of an Ultraviolet-Spectrophotometric Method for Analysis of Esterquat-Containing Flotation Collectors in Aqueous Solutions
Ibragimova, Olga; Kleiv, Rolf Arne (Journal article; Peer reviewed, 2018)In this study, a rapid and simple ultraviolet‐spectrophotometric method was developed and validated for the quantitative determination of esterquat‐containing flotation collector FLOT 2015 in aqueous solutions. This method ... -
