Selective Flotation of Pyrite from Galena Using Chitosan

29-7-2019Pyrite is a major gangue mineral associated with galena and other valuable minerals and it is necessary to selectively remove pyrite to upgrade the lead concentrate by froth flotation In this study the flotation experiments of a single mineral and mixed minerals were performed using chitosan with different molecular weights (MW Get price

1 Introduction

This followed work by a number of authors who identified that galena flotation was strongly potential-related [19] [20] 2) Collectorless flotation of galena being strongest after grinding with stainless steel or ceramic media was attributed to oxidation of the galena surface leading to formation of hydrophobic elemental sulphur Get price
