Challenges in Sulphide Mineral Processing
Scientists and technologists in world over are making large efforts to streamline the conventional technological schemes of ore processing, in particular froth flotation towards reducing overall costs, limiting the use of dangerous substances, decreasing waste streams and improving waste disposal. Hitherto, search for such innovations has been performed mainly empirically and there is an urgent...
متن کاملEffect of Oxygen and Micro-Cracking on the Flotation of Low Grade Nickel Sulphide Ore
This study investigated the effect of oxygen and micro-cracking on the flotation of low grade nickel sulphide ore. The ore treated contained serpentine minerals which have a history of being difficult to process efficiently. The use of oxygen as a bubbling gas has been noted to be effective because it increases the pulp potential. The desired effect of micro cracking the ore is that the nickel ...
متن کاملReflectance Spectroscopy in the Analysis of Mineral Flotation Slurries
Effective monitoring and control of a mineral flotation process necessitates accurate and rapid on-line analysis of the slurry flows. Recent development of lightweight and low-cost visible and near-infrared (VNIR) imaging spectrographs has provided new interesting possibilities also in mineral froth and slurry analysis. The intelligent combination of VNIR reflectance spectroscopy with the tradi...
متن کاملIntegrated Approaches for the Study of Real Mineral Flotation Systems
It is more common than not, for mineral processing studies to proceed via the examination of model flotation systems with the resulting data often lacking statistical verification. The resultant concentrates and tails may then be subjected to a restricted range of analyses, for diagnosis of the flotation behavior variations observed, that themselves bias the outcomes. For instance surface analy...
متن کاملDetection and analysis of oscillations in a mineral flotation circuit
A novel mineral slurry assaying method combining visible and near-infrared reflectance spectroscopy and traditional X-ray fluorescence has recently been developed. The improved method is capable of high-frequency assaying of slurry grades in zinc and copper flotation, thus being able to reveal possible rapid oscillations in the grades. In this study, the new measurements are used to detect osci...
