Mintek researchers, Ashma Singh, Senior Technical Specialist and Getrude Marape, Principal Engineer in the Mineral Processing Division presented papers on phosphate beneficiation at the  ECI Beneficiation of Phosphates IX Conference 2022 held in Helsinki, Finland from 05 -10 to June.

Their papers formed part of  Mintek’s research, SET development and commercial testwork on phosphates. Singh’s paper is entitled “Beneficiation of Medium and Low-Grade African Phosphates in the context of stimulating supply”. The paper forms part of her PhD studies and aims to develop knowledge in phosphate processing, and derive best practices and technology beneficiation solutions for the treatment of medium and low-grade/complex ore bodies.  Singh said, “The study is being undertaken with industry support and is currently co-supervised through the Florida Institute of Phosphate Research (FIPR).”

Singh co-chaired the ‘Physical Separation and Data Analysis’ technical session with interest from phosphate rock producers globally regarding Mintek’s expertise on the subject matter.

Marape’s paper is entitled “Flotation processing of Elandsfontein Sedimentary Phosphate Ore from South Africa. The paper investigated the flotation of phosphorite from Kropz largest sedimentary operation, Elandsfontein in South Africa.

Marape said that the conference was an eye-opener which allowed her to learn more about phosphates beneficiation and downstream processing.

In addition, through networking they visited the Yara Siilinjarvi which is Finland’s largest low grade phosphate mine where they were exposed to the mining operations, beneficiation plant, acid and fertilizer production. They also visited the Minerals Processing Division of the University of Aalto, Finland.

Phosphate mining is one of the world’s largest mining industries in terms of the value of production and annual tonnage. The Beneficiation of Phosphates conference has been established as the only conference of international significance focusing on phosphate mineral processing.
