Eliminating Negative Effects

Published by , Editor
Global Mining Review,

In the May/June issue of Global Mining Review, Wendel Rodrigues, Wagner Silva, Pierre Fernandes, Pedro Gonzaga, and Ronaldo Fonseca, Clariant, describe how using a new reagent suite can reduce the negative effects of aluminosilicate minerals on gold flotation. This special report lists all the references contained within the article.
