rock ilmenite processing

CHAPTER 1 INTRODUCTION 1.1 INDUSTRY BACKGROUND

1.1.2 Hard Rock Mineral Processing Hard rock mineral processing is used in cases where ilmenite occurs in hard rock deposits and not in the form of mineral sands. This type of processing is used in Canada and Norway to concentrate hard rock ilmenite. In both cases the ilmenite product is smelted to produce pig iron and high-titania slag. The
