Iron ore extraction techniques
Iron ore reserves are normally found within a few meters from the ground surface, and most of the major mines of the world are operating an opencut system, which requires little sophistication, except in terms of the equipment used and the quantities needed to be mined for operations to be cost-effective. This chapter will look at case …

Mineral Processing and Extractive Metallurgy of the Rare Earths …
Abstract. This chapter is about mineral processing of the rare earths (making the mined ore into a concentrate of the valuable minerals), and extractive metallurgy of the rare earths (how to get the metals out of the concentrate). The mineral processing of three well-known exploited ore deposits is discussed in more detail.
