Miningto The Processing PlantCrushing and MillingSeparation and ConcentrationWaste and Products from Mineral ProcessingMine ClosureIn the beginning of a mining project the area must first be cleared of topsoil to reach the bedrock. This material is called overburden, and stripping is done to remove it. The soil can be used within the mine, for example to construct roads or other infrastructure. In some mines also the overburden is part of the mineral resource. Explosives are used to break and fragment the ore and waste rock. Shallow holes are drilled and filled with explosives blasting the rock to pieces. This is called drilling and blasting. The blast

Gangue Mineral - an overview ScienceDirect Topics

If the gangue mineral in an iron ore is predominantly quartz, reverse flotation is usually used in the cleaning stage to improve the concentrate grade. Figure 9.13 presents a typical flow sheet for processing an oxidized iron ore containing about 30% Fe using a combination of SLon magnetite separators and reverse flotation. The ore is mainly composed of magnetite, hematite, martite, and quartz.

9 Ore Deposits and Economic Minerals – Mineralogy

Many different mineral commodities are important to modern society. However, when mineralogists think about mining, they are generally thinking of ore minerals that are the sources of important metals, or of minerals that have specific, highly valued properties (e.g., asbestos, micas, potash, and gems of all sorts).That is what we will focus on in most of the rest of this chapter.
