Title: Innovations by Geoffrey Senior: Pioneering Processes in Sulphide Concentration

Introduction

Geoffrey Senior, an inventive mind based in Mount Claremont, Australia, has contributed significantly to the field of mineral processing with his two innovative patents. Working with WMC Resources Limited, Geoffrey's work focuses on enhancing the techniques for sulphide mineral flotation and concentration.

Latest Patents

Geoffrey Senior's latest patents include:

1. **Process for Sulphide Concentration**: This invention introduces a gravity/flotation circuit where a mineral stream undergoes a two-stage size separation. In this process, the middlings stream is subjected to flotation for nickel sulphide recovery, while magnesia is rejected or depressed and further concentrated through gravity separation. The innovative discovery that a significant amount of MgO minerals within the 30 to 100 micron size fraction are well liberated allows for effective physical separation, capitalizing on the differing specific gravities of nickel sulphide and magnesia minerals.

2. **PH Adjustment in the Flotation of Sulphide Minerals**: This patent describes a process for flotation of sulphide minerals by separating a flotation pulp into coarse and fine streams based on particle size. Alkali and depressants are added to the coarse stream, while acid and activators are utilized for the fine stream. This method ensures optimized conditions during different flotation stages for both streams, enhancing the overall efficiency of sulphide mineral separation.
