Mineralogical and metallurgical examination of fluorosilicate mineral floatation in the Ok Tedi circuit

Pangum, L.S., Lauder, D.W., Manlapig, E.V., Mackinnon, I.R., & Glatthaar, J.W. (1998) Mineralogical and metallurgical examination of fluorosilicate mineral floatation in the Ok Tedi circuit. In Mine to Mill Conference, 11 - 14 October 1998, Brisbane, QLD.

Abstract

The Ok Tedi copper orebody consists of porphyry and skarn orebodies. The skarn orebodies, identified by different mineralogy, are the source of high intermittent fluorine levels in the mill concentrates. This paper discusses the results of the work undertaken to characterize the various fluorine-bearing minerals in samples of final copper concentrates and the distribution of fluorine amongst the minerals. Quantification of each mineral in mill feed and various flotation streams at Ok Tedi enables an understanding of the quantitative response of fluorine-bearing minerals to flotation. The metallurgical behavior of fluorine in the flotation process is also discussed.

Impact and interest:

Citation counts are sourced monthly from Scopus and Web of Science® citation databases.

These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.

Citations counts from the Google Scholar™ indexing service can be viewed at the linked Google Scholar™ search.
