Abstract

In this work froth flotation studies with LiAlO2 (lithium-containing phase) and Melilite solid solution (gangue phase) are presented. The system was optimized with standard collectors and with compounds so far not applied as collectors. Furthermore, the principle of self-assembled monolayers was introduced to a froth flotation process for the first time resulting in excellent yields and selectivities.

Highlights

  • In this work froth flotation studies with ­LiAlO2 (lithium-containing phase) and Melilite solid solution (gangue phase) are presented

  • In this work froth flotation studies with ­LiAlO2 and Melilite solid solution are presented

  • From the composition of a Umicore slag mainly based on the ­Li2O–MgO–Al2O3–SiO2–CaO slag system with high aluminum content, it is observed that Li is present in the slag in the form of the L­ iAlO26. ­LiAlO2 contains about 10% lithium, while the critical lithium-bearing mineral Spodumene contains only 3.7% lithium

Summary

Introduction

In this work froth flotation studies with ­LiAlO2 (lithium-containing phase) and Melilite solid solution (gangue phase) are presented. Froth flotation is based on the selective interaction of collectors with surfaces of different minerals.
