Materials for MINING AND MINERALS PROCESSING

Invited talk

Scanning Electron Microscopy (SEM) coupled with Energy Dispersive X-ray Spectroscopy (EDS) is the cornerstone in geological analysis, facilitating detailed mineralogical characterization from thin sections and particulate rock samples. Backscattered Electron (BSE) imaging, EDS analysis, and Cathodoluminescence (CL), provide invaluable insights into the composition and microstructure of...

ABSTRACT

In Botswana mining is well-known to have surpassed the significant contribution to gross domestic product (GDP) made by agriculture, and more specifically the beef industry post-independence. Mining activities such as the diamond production has now become an important contributor to the development of the country and livelihood as a whole. However, mining operation in general do...

123. Interaction Types, Impacts And Bio-Flotation Mechanisms For Spodumene Concentration: A Critical Review Of The Literature.

Mrs Everjoy MUCHEFA (University of Johannesburg)

Materials for MINING AND MINERALS PROCESSING

Contributed Oral Presentation

This paper is a literature review aiming to critic the documented findings on how micro-organisms aided spodumene concentration from hard rocks can be carried out not only efficiently but also in environmentally and friendly process. The paper evaluates the use of microorganisms to enhance the floatability of spodumene with an efficient management of the gangue material. With particular...

434. Lithium-ion selective solid phase adsorption from aqueous solution.

Dr Tavengwa Bunhu (Chinhoyi University of Technology)

Materials for MINING AND MINERALS PROCESSING

Contributed Oral Presentation

Lithium is a strategic and critical mineral in the global transition to clean energy and in addressing the energy challenges faced across the world. Zimbabwe is endowed with the largest lithium reserves/deposits in Africa. The extraction of lithium from its ores entails acid or alkaline leaching followed by a series of time- and raw material-consuming concentration and purification steps to...

426. PRODUCTION OF RECYCLED LITHARGE AND CUPELS FROM Pb LADEN CUPEL WASTE GENERATED IN PRECIOUS METAL EXTRACTION: AN ENHANCED HYBRID APPROACH TOWARDS LONG TERM ENVIRONMENTAL POLLUTION CONTROL.

STEPHEN NYONI (Chinhoyi University of Technogy)

Materials for MINING AND MINERALS PROCESSING

Contributed Oral Presentation

Lead laden cupels are being produced in tonnes by mining firms and dumped into the environment on a daily basis. Disposal of these used cupels present a long term environmental challenge due to the high levels of Pb. In this work, a circular economy oriented approach on the recovery of lead from waste cupels is reported. In the proposed lead recovery protocol, lead was leached at room...
